1 John 5

1 John 5:1

Alexander of Alexandria: As in a certain place the Lord Himself testified, saying, “Every one that loveth Him that begat, loveth Him also that is begotten of Him.”

Andreas of Caesarea: By practicing virtue, those who are born of God have become his children, his friends, just as Abraham was. Once again John touches on the doctrine of truth, revealing the depths of the unbelief of the heretics. — CATENA

Augustine of Hippo: Who is he that believeth not that Jesus is the Christ? He that does not so live as Christ commanded. For many say, “I believe:” but faith without works saveth not. Now the work of faith is Love, as Paul the apostle saith, “And faith which worketh by love.” Thy past works indeed, before thou didst believe, were either none, or if they seemed good, were nothing worth. For if they were none, thou wast as a man without feet, or with sore feet unable to walk: but if they seemed good, before thou didst believe, thou didst run indeed, but by running aside from the way thou wentest astray instead of coming to the goal. It is for us, then, both to run, and to run in the way. He that runs aside from the way, runs to no purpose, or rather runs but to toil. He goes the more astray, the more he runs aside from the way. What is the way by which we run? Christ hath told us, “I am the Way.” What the home to which we run? “I am the Truth.” By Him thou runnest, to Him thou runnest, in Him thou restest. — Ten Homilies on 1 John 10

Augustine of Hippo: But, that we might run by Him, He reached even unto us: for we were afar off, foreigners in a far country. Not enough that we were in a far country, we were feeble also that we could not stir. A Physician, He came to the sick: a Way, He extended Himself to them that were in a far country. Let us be saved by Him, let us walk in Him. This it is to “believe that Jesus is the Christ,” as Christians believe, who are not Christians only in name, but in deeds and in life, not as the devils believe. For “the devils also believe and tremble,” as the Scripture tells us. What more could the devils believe, than that they should say, “We know who thou art, the Son of God?” What the devils said, the same said Peter also. — Ten Homilies on 1 John 10

Augustine of Hippo: When the Lord asked them who He was, and whom did men say that He was, the disciples made answer to Him, “Some say that thou art John the Baptist; some, Elias; and others, Jeremias, or one of the prophets. He saith unto them, But whom say ye that I am? And Peter answered and said, Thou art the Christ, the Son of the Living God.” And this he heard from the Lord: “Blessed art thou, Simon Barjona; for flesh and blood hath not revealed it unto thee, but my Father which is in heaven.” See what praises follow this faith. “Thou art Peter, and upon this rock I will build my Church.” What meaneth, “Upon this rock I will build my Church”? Upon this faith; upon this that has been said, “Thou art the Christ, the Son of the Living God. Upon this rock,” saith He, “I will build my Church.” — Ten Homilies on 1 John 10

Augustine of Hippo: So then, Peter saith, “Thou art the Christ, the Son of the Living God:” the devils also say, “We know who thou art, the Son of God, the Holy One of God.” This Peter said, this also the devils: the words the same, the mind not the same. And how is it clear that Peter said this with love? Because a Christian’s faith is with love, but a devil’s without love. How without love? Peter said this, that he might embrace Christ; the devils said it, that Christ might depart from them. For before they said, “We know who thou art, the Son of God,” they said, “What have we to do with thee? Why art thou come to destroy us before the time?” It is one thing then to confess Christ that thou mayest hold Christ, another thing to confess Christ that thou mayest drive Christ from thee. So then ye see, that in the sense in which he here saith, “Whoso believeth,” it is a faith of one’s own, not as one has a faith in common with many. Therefore, brethren, let none of the heretics say to you, “We also believe.” For to this end have I given you an instance from the case of devils, that ye may not rejoice in the words of believing, but search well the deeds of the life. — Ten Homilies on 1 John 10

Augustine of Hippo: Let us see then what it is to believe in Christ; what to believe that Jesus, He is the Christ. He proceeds: “Whosoever believeth that Jesus is the Christ, is born of God.” But what is it to believe that? “And every one that loveth Him that begat Him, loveth Him also that is begotten of Him.” To faith he hath straightway joined love, because faith without love is nothing worth. With love, the faith of a Christian; without love, the faith of a devil: but those who believe not, are worse than devils, more stupid than devils. Some man will not believe in Christ: so far, he is not even upon a par with devils. A person does now believe in Christ, but hates Christ: he hath the confession of faith in the fear of punishment, not in love of the crown: thus the devils also feared to be punished. Add to this faith love, that it may become a faith such as the Apostle Paul speaks of, a “faith which worketh by love:” thou hast found a Christian, found a citizen of Jerusalem, found a fellow-citizen of the angels, found a pilgrim sighing in the way: join thyself to him, he is thy fellow-traveller, run with him, if indeed thou also art this. — Ten Homilies on 1 John 10

Augustine of Hippo: “Every one that loveth Him that begat Him, loveth Him also that is begotten of Him.” Who “begat”? The Father. Who “is begotten”? The Son. What saith he then? “Every one that loveth the Father, loveth the Son.” — Ten Homilies on 1 John 10

Bede: And everyone who loves the one who begot, loves also the one, etc. With marvelous skill in preaching, blessed John took care to incite us to the love of our neighbor, first noting that everyone who perfectly believes is born of God, then suggesting how just it is that the one who loves God should love also the one born of God. For if anyone is so slow as to neglect to love a man because he is a man, because he endures the same pilgrimage on earth with him, he should be admonished to at least love him for this reason, that he is born of God, that he is made a partaker with him of divine grace, that he expects the same rewards of heavenly life with him. Indeed, this exhortation particularly pertains to those who have not only become our brothers by the companionship of human nature but also by the profession of faith. However, because there are some who love their neighbors but because of kinship or for some temporal benefit, the holy evangelist rightly reveals what true neighborly love is by adding: — Commentary on the Catholic Epistles

Caesarius of Arles: John immediately joined love to faith, because without love faith is useless. According to charity, faith belongs to Christians, but without love it belongs to the demons. Moreover, those who do not believe are even worse than the demons. — SERMONS 186.1

Cyril of Jerusalem: We can turn this around and say that anyone who despises the Begotten also despises the One who begat him. — Catechetical Lecture 11:7

Didymus the Blind: This describes everyone who is born of God and does what God wants him to do. — COMMENTARY ON 1 JOHN

Irenaeus: These words agree with what was said in the Gospel, that “the Word was made flesh, and dwelt among us.” Wherefore he again exclaims in his Epistle, “Every one that believeth that Jesus is the Christ, has been born of God;” knowing Jesus Christ to be one and the same, to whom the gates of heaven were opened, because of His taking upon Him flesh: who shall also come in the same flesh in which He suffered, revealing the glory of the Father. — Against Heresies Book 3

Oecumenius: Everyone who believes that Jesus is the Christ is born of God. And whoever loves the one who created him loves also the one who is born of him. By this we know that we love the children of God, when we love God and keep his commandments. For this is the love of God, that we keep his commandments: and his commandments are not burdensome. For whatever is born of God overcomes the world. And this is the victory that overcomes the world, our faith. Who is it that overcomes the world except the one who believes that Jesus is the Son of God? John confirms the discourse again with others, thereby strengthening it in a certain way: If we have received the command from the Master to love one another mutually, surely if we believe that our Master and Teacher is Jesus Christ, who is Christ in the same way that God and man are: we shall also observe his commandments as both a Teacher and as God. Furthermore, believing him to be God, we are called his children: just as it is said in the Gospels: “But as many as received him, that is, as many as believed in him, he gave them the power to become the children of God.” (Jn. 1:12) If, therefore, we are born of him, we shall also fulfill what is fitting for him who begot us. What is this? That we love him who created us, since it follows from the nature of children that they love their parents. Since this is the case, all of us who have believed are born of the same. If we are born of the same, we are also indebted to love one another: both because we are brothers and because we are born of the same. And John adds this persuasion: that whoever loves the one who created him loves also the one who is born of him. Then he uses a change of discourse and says that love for brothers or the children of God confirms love for Him who created. For John previously said: “he who loves God must love his brother also. (1 Jn. 4:21):” now, however, in an inverted discourse, he says that whoever loves the children of God also loves God: and he places the sign of love for God as love for the brother. Then he also says that love for God brings about the observance of His commandments: rightly saying this: for “Whoever loves me,” says the Savior, “keeps my commandments."(Jn. 14:21 “For this is the love of God.” In the superlative (ὑπερθατῷ), that what is proposed should be understood in this way: For this is the love of God that we keep His commandments, because whatever is born of God overcomes the world. Furthermore, and his commandments are not burdensome, it has been interpolated. “and His commandments are not burdensome.” Not as Christ said, “My yoke is easy (Matt. 11:30);” thus He Himself said that the commandments are light, but that they are not burdensome: for to him who is brought to virtue, even what is light is considered very heavy; just as to one who has lost strength and health, everything that makes for good, even what is very light, seems heavy. Indeed, because the commandments of God seemed burdensome to some, as they are God’s, for this reason He says that His commandments are not burdensome. For what burden is there in loving a brother? Furthermore, what burdensome does it cause to visit one who is in prison? For he does not command to free him who is in prison, which would be difficult, but only to visit; nor does he command to free the sick from their illness, but only to visit; nor does he command to set a lavish table for the hungry, nor to provide clothing to the naked prepared with unnecessary embellishment; but he requires what provides necessary use for him who is hungry or naked. After he has arranged these things in this way, he adds to what has already been said another thing that leads to the showing of love, what is that? Victory (ὴν νίκην). For John says: you who establish yourselves as sons of God by love for your neighbor, you already have this that accompanies that excellent deed, namely, to conquer the world; For whatever is born of God overcomes the world. Then John adds victory, and what is the cause of victory, and he says that both agree with faith, namely, that which is towards God, which also born of God, has conquered and driven away all disbelief; neither Jew, nor Greek, nor Heretic can do anything against it. And since faith does not conquer alone, but together with the one who possesses it, John adds: “And who is it that overcomes the world, except the one who believes that Jesus is the Son of God?” But who is this Jesus? “He who came by water and blood, Jesus Christ”. (1 Jn. 5:6) — Commentary on 1 John

1 John 5:2

Augustine of Hippo: “In this we know that we love the sons of God.” What is this, brethren? Just now he was speaking of the Son of God, not of sons of God: lo, here one Christ was set before us to contemplate, and we were told, “Whosoever believeth that Jesus is the Christ is born of God: and every one that loveth Him that begat,” i.e. the Father, “loveth Him also that is begotten of Him,” i.e. the Son, our Lord Jesus Christ. And he goes on: “In this we know that we love the sons of God;” as if he had been about to say, “In this we know that we love the Son of God.” He has said, “the sons of God,” whereas he was speaking just before of the Son of God - because the sons of God are the Body of the Only Son of God, and when He is the Head, we the members, it is one Son of God. — Ten Homilies on 1 John 10

Augustine of Hippo: Therefore, he that loves the sons of God, loves the Son of God, and he that loves the Son of God, loves the Father; nor can any love the Father except he love the Son, and he that loves the sons, loves also the Son of God. What sons of God? The members of the Son of God. And by loving he becomes himself a member, and comes through love to be in the frame of the body of Christ, so there shall be one Christ, loving Himself. For when the members love one another, the body loves itself. “And whether one member suffer, all the members suffer with it; or one member be honored, all the members rejoice with it.” And then he goes on to say, “Now ye are the body of Christ, and members.” — Ten Homilies on 1 John 10

Augustine of Hippo: John was speaking just before of brotherly love, and said, “He that loveth not his brother whom he seeth, how can he love God whom he seeth not?” But if thou lovest thy brother, haply thou lovest thy brother and lovest not Christ? How should that be, when thou lovest members of Christ? When therefore thou lovest members of Christ, thou lovest Christ; when thou lovest Christ, thou lovest the Son of God; when thou lovest the Son of God, thou lovest also the Father. The love therefore cannot be separated into parts. Choose what thou wilt love; the rest follow thee. Suppose thou say, I love God alone, God the Father. Thou liest: if thou lovest, thou lovest Him not alone; but if thou lovest the Father, thou lovest also the Son. — Ten Homilies on 1 John 10

Augustine of Hippo: Behold, sayest thou, I love the Father, and I love the Son: but this only, the Father God and the Son God, our Lord Jesus Christ, who ascended into heaven, and sitteth at the right hand of the Father, that Word by which all things were made, and “the Word was made flesh, and dwelt in us:” this alone I love. Thou liest; for if thou lovest the Head, thou lovest also the members; but if thou lovest not the members, neither lovest thou the Head. Dost thou not quake at the voice uttered by the Head from Heaven on behalf of His members, “Saul, Saul, why persecutest thou ME?” The persecutor of His members He called His persecutor: His lover, the lover of His members. Now what are His members, ye know, brethren: none other than the Church of God. — Ten Homilies on 1 John 10

Augustine of Hippo: “In this we know that we love the sons of God, in that we love God.” And how? Are not the sons of God one thing, God Himself another? But he that loves God, loves His precepts. And what are the precepts of God? “A new commandment give I unto you, that ye love one another.” Let none excuse himself by another love, for another love; so and so only is it with this love: as the love itself is compacted in one, so all that hang by it doth it make one, and as fire melts them down into one. It is gold: the lump is molten and becomes some one thing. But unless the fervor of charity be applied, of many there can be no melting down into one. “That we love God,” by this “know we that we love the sons of God.” — Ten Homilies on 1 John 10

Bede: In this we know that we love the children of God, etc. Therefore, he alone is proven to love his neighbor rightly who is known to burn with the love of the Creator. And lest anyone deceive himself about the love of the Creator, professing that he loves by word alone, after having said: In this we know that we love the children of God, when we love God, he added, and we keep His commandments. — Commentary on the Catholic Epistles

Theophylact of Ohrid: If we love God, then we must also love those whom God has brought to birth and who have become our brothers and sisters. Loving one another is a sign of how much we love God. — COMMENTARY ON 1 JOHN

1 John 5:3

Andreas of Caesarea: Keeping the commandments is both the form and substance of our love for God. Those who obey them are brought close to God by them. If someone looks at them in the wrong way and says that they are heavy to bear, he is merely revealing his own weakness. — CATENA

Bede: For this is the love of God, that we keep His commandments. The Lord Himself says this: If anyone loves me, he will keep my word (John XIV). Therefore, the proof of love is the exhibition of work. For we truly love if we constrain ourselves to His commandments from our will. For he who still flows with illicit desires certainly does not love God, because he contradicts Him in his will. — Commentary on the Catholic Epistles

Bede: And His commandments are not burdensome. The Lord Himself says: My yoke is easy, and my burden is light (Matt. XI). It should not appear contrary to the words of the Lord or blessed John that the Lord Himself says elsewhere that the gate is narrow, and the way is hard that leads to life (Matt. VII); and the prophet says to Him: For the words of your lips, I have kept hard ways (Psalm XVI); and the apostle: For through many tribulations we must enter the kingdom of God (Acts XIV). For what is inherently hard and rough, the hope of heavenly rewards and the love of Christ makes light. Indeed, it is hard to suffer persecutions for righteousness, but what makes it sweet is that for those who suffer thus, the kingdom of heaven belongs. Hence it is well added: — Commentary on the Catholic Epistles

Clement of Alexandria: For the love meant is the love of God. “And this is the love of God “says John, “that we keep His commandments; “. “This is the love of God, that we keep His commandments.” — The Instructor Book 3

Didymus the Blind: The substance and ground of the love we ought to have for God is obedience to his commandments. — COMMENTARY ON 1 JOHN

1 John 5:4

Andreas of Caesarea: This means that such a person has overcome all evil and ungodliness. For our faith has destroyed all ignorance and driven out all darkness. — CATENA

Bede: For whatever is born of God overcomes the world. Therefore, God’s commandments are not heavy because all who devote themselves to them in true devotion equally despise the adversities and blandishments of the world with equal mind, even loving death itself as the entrance to the heavenly homeland. And lest anyone trust that he can overcome the world or its luxuries or labors by his virtue, it is deliberately added: — Commentary on the Catholic Epistles

Bede: And this is the victory that overcomes the world: our faith. Specifically, that faith which works through love; that faith by which we humbly seek the help of Him who said: In the world you will have tribulations, but take courage, I have overcome the world (John 16). — Commentary on the Catholic Epistles

Cyril of Alexandria: Neither a Jew nor a pagan nor a heretic can do anything in the face of this victory which is ours through faith. — CATENA

Theophylact of Ohrid: Once you have become brothers and sisters in love, you must go on to the next stage, which is to overcome the world. For those who have been born again in God must expel every kind of unbelief from their midst. — COMMENTARY ON 1 JOHN

1 John 5:5

Bede: Who is he that overcomes the world, etc.? He overcomes the world who, believing that Jesus is the Son of God, combines works worthy of that faith. But does the faith and confession of His divinity alone suffice for salvation? See what follows. — Commentary on the Catholic Epistles

1 John 5:6

Andreas of Caesarea: What flowed from his side was also the blood which cleanses us from sin and sanctifies the people of God.… It was not a mere man who appeared at the Jordan but the incarnate Word of God, to whom the Father also bore witness: “This is my beloved Son in whom I am well pleased.” Similarly, when he was hanging on the cross, what sounded to the people like thunder was the voice of God speaking at the moment that his blood fell to the ground. — CATENA

Bede: This is He who came by water and blood, Jesus Christ. He who was the eternal Son of God became man in time, so that He who created us by His divine power might recreate us by the weakness of His humanity. He came by water and blood, namely the water of baptism and the blood of His passion. He not only deigned to be baptized for our cleansing to consecrate and deliver to us the sacrament of baptism, but also gave His blood for us, redeeming us by His passion, that we might be nourished unto salvation by the sacraments. — Commentary on the Catholic Epistles

Bede: And the Spirit is He who testifies because Christ is the truth. When the Lord was baptized in the Jordan, the Holy Spirit descended upon Him in the form of a dove, bearing witness to Him as the truth, that is, the true Son of God, the true mediator between God and men, the true Redeemer and Reconciler of mankind, who is indeed free from all stain of sin, truly able to take away the sins of the world. As also the Baptist, understanding when he saw the coming of the same Spirit, said: He who sent me to baptize with water said to me, Upon whom you see the Spirit descending and remaining on Him, He it is who baptizes with the Holy Spirit. And I have seen and have borne witness that this is the Son of God (John 1). Therefore, since the Spirit testifies that Jesus Christ is the truth, He calls Himself the truth, the Baptist proclaims Him as the truth, the son of thunder evangelizes the truth, let the blasphemers be silent, who maintain that this is a phantasm; let the memory of those perish from the earth who deny that He is truly either God or man. — Commentary on the Catholic Epistles

Clement of Alexandria ((as quoted by Cassiodorus)): He says, “This is He who came by water and blood;” and again -

“For there are three that bear witness, the spirit,” which is life, “and the water,” which is regeneration and faith, “and the blood,” which is knowledge; “and these three are one.” For in the Saviour are those saving virtues, and life itself exists in His own Son. — From the Latin Translation of Cassiodorus

Irenaeus: , and calls them into his own kingdom? And why is his goodness, which does not save all — Against Heresies Book IV

Ishodad of Merv: John calls Christ’s baptism “water” and his passion “blood.” He fulfilled all the dispensations for our sake, by means of his baptism, his passion and by the Holy Spirit. — COMMENTARIES

Oecumenius: This is he who came by water and blood, Jesus Christ: not by water only, but by water and blood. And it is the Spirit who bears witness, because the Spirit is the truth. For there are three that bear witness: the Spirit, the water, and the blood; and these three are one. Since John also remembered the birth of children, saying: “Everything that is born of God” (1 Jn. 5:4): these things, however, happen to us through sacred baptism; therefore he says: “This is he who came by water and blood, Jesus Christ.” And for what purpose did he come? To renew us and make us children of God. For this is also understood as a consequent statement, so that this is the meaning. “For whatever is born of God overcomes the world.” But how was it born? He says, by water and blood. Indeed, Jesus Christ who came renews through water and blood. John adds again, repeating the statement, saying: not by water only, namely regenerating, but by water and blood. For he wishes first to show the name of Christ who adopted us: since the man who was in him, the first adopted by God, also gave us through his adoption such dignity, which has been demonstrated three times: namely in the baptism in the Jordan, when the heavenly Father testified that he who was being baptized was his beloved Son. (Matt. 3:17) But who was he that entered the water except the man who was taken up together with the Word of God? Certainly, he who appeared in secret, for he needed a testimony. Therefore, by the water, that is, in the baptism that takes place through water, the Son of God, Jesus, was demonstrated to be so by the testimony of the Father. And by the blood, when he was to be crucified, he said: “Glorify me, Father,” (Jn. 17:1) and a voice was heard: “And I have glorified and will glorify again;” (Jn. 12:28) which those who heard thought to be thunder. By the Spirit, however, when He rose from the dead as God. For it is left to God alone to raise Himself. Furthermore, by the term Spirit, God is signified: since the Spirit is God. (Jn. 4:24) Therefore, since three bear witness to Jesus’ adoption, namely baptism, crucifixion, and resurrection, there is no uncertainty in the Lord’s adoption: by which adoption He also granted us, as He who was the first fruits of the entire human mass (Rom. 11:16), to be children of God. And these three are united in one Christ: for this is what it signifies, saying: “These three are one,” that is, as a testimony concerning Christ. It should be noted that some of the fathers received the Spirit, not because of the resurrection, but the Father Himself when He cried out in the Jordan: “This is my beloved Son (Matt. 17:5);” because God is also called Spirit, as we have predicted. — Commentary on 1 John

Tertullian: We have indeed, likewise, a second font, (itself withal one with the former, ) of blood, to wit; concerning which the Lord said, “I have to be baptized with a baptism,” when He had been baptized already. For He had come “by means of water and blood,” just as John has written; that He might be baptized by the water, glorified by the blood; to make us, in like manner, called by water, chosen by blood. — On Baptism

1 John 5:7

Bede: Since there are three who bear witness on earth, etc. The Spirit has borne witness that Jesus is truth, when it descended upon Him at His baptism. For if he were not truly the Son of God, by no means would the Holy Spirit have come to Him with such a great manifestation. Water and blood also bore witness that Jesus is truth, when from His side on the cross, after He had died, they flowed out: which could not have happened at all, if He did not have a true nature of flesh. And also this that before His passion, when He prayed, His sweat became like great drops of blood falling to the ground (Luke 22), gives testimony to the truth of the flesh He had assumed. Nor should it be ignored that in this also blood and water bore witness to Him, that from His side after death they flowed out vividly, which was against the nature of dead bodies, and therefore was apt for mysteries, and was fitting as a testimony of the truth, namely showing that the very body of the Lord would live more gloriously after being resurrected, and that His very death would grant us life. This too, that His sweat fell to the ground like drops of blood, bore witness to that holy mystery that He would wash the whole Church all over the world with His blood. Therefore, there are three who bear witness to the truth. — Commentary on the Catholic Epistles

Bede: And (he says) the three are one. For these remain indivisible, and none of them is separated from its connection, because divinity is not to be believed without true humanity, nor humanity without true divinity. But in us also these are one, not by nature of the same substance, but by the operation of the same mystery. For, as the blessed Ambrose says: “The Spirit renews the abiding, water leads to washing, blood pertains to redemption.” For the Spirit has made us sons of God through adoption, the wave of the sacred font washes us, the blood of the Lord has redeemed us. Therefore, one invisible, the other visible testimony, follows the spiritual sacrament. — Commentary on the Catholic Epistles

Cyprian: And again it is written of the Father, and of the Son, and of the Holy Spirit, “And these three are one.”

1 John 5:8

Augustine of Hippo: What was it that flowed from Jesus’ side if not the sacrament which believers receive? The Spirit, the blood and the water—the Spirit which he gave up, the blood and water which flowed from his side. The church is signified as being born from this blood and water. — SERMONS 5.3

Augustine of Hippo: I would not have thee mistake that place in the epistle of John the apostle where he saith, “There are three witnesses: the Spirit, and the water, and the blood: and the three are one.” Lest haply thou say that the Spirit and the water and the blood are diverse substances, and yet it is said, “the three are one:” for this cause I have admonished thee, that thou mistake not the matter. For these are mystical expressions, in which the point always to be considered is, not what the actual things are, but what they denote as signs: since they are signs of things, and what they are in their essence is one thing, what they are in their signification another. If then we understand the things signified, we do find these things to be of one substance. Thus, if we should say, the rock and the water are one, meaning by the Rock, Christ; by the water, the Holy Ghost: who doubts that rock and water are two different substances? yet because Christ and the Holy Spirit are of one and the same nature, therefore when one says, the rock and the water are one, this can be rightly taken in this behalf, that these two things of which the nature is diverse, are signs of other things of which the nature is one. — Ten Homilies on 1 John 10

Augustine of Hippo: Three things then we know to have issued from the Body of the Lord when He hung upon the tree: first, the spirit: of which it is written, “And He bowed the head and gave up the spirit:” then, as His side was pierced by the spear, “blood and water.” Which three things if we look at as they are in themselves, they are in substance several and distinct, and therefore they are not one. But if we will inquire into the things signified by these, there not unreasonably comes into our thoughts the Trinity itself, which is the One, Only, True, Supreme God, Father and Son and Holy Ghost, of whom it could most truly be said, “There are Three Witnesses, and the Three are One:” so that by the term Spirit we should understand God the Father to be signified; as indeed it was concerning the worshipping of Him that the Lord was speaking, when He said, “God is a Spirit:” by the term, blood, the Son; because “the Word was made flesh:” and by the term water, the Holy Ghost; as, when Jesus spake of the water which He would give to them that thirst, the evangelist saith, “But this said He of the Spirit which they that believed on Him were to receive.” — Ten Homilies on 1 John 10

Augustine of Hippo: Moreover, that the Father, Son, and Holy Ghost are “Witnesses,” who that believes the Gospel can doubt, when the Son saith, “I am one that bear witness of myself, and the Father that sent me, He beareth witness of me.” Where, though the Holy Ghost is not mentioned, yet He is not to be thought separated from them. Howbeit neither concerning the Spirit hath He kept silence elsewhere, and that He too is a witness hath been sufficiently and openly shown. For in promising Him He said, “He shall bear witness of me.” These are the “Three Witnesses, and the Three are One, because of one substance. But whereas, the signs by which they were signified came forth from the Body of the Lord, herein they figured the Church preaching the Trinity, that it hath one and the same nature: since these Three in threefold manner signified are One, and the Church that preacheth them is the Body of Christ. — Ten Homilies on 1 John 10

Ishodad of Merv: The three things are one because everything was accomplished by the one Christ. — COMMENTARIES

Leo the Great: This means the Spirit of sanctification, the blood of redemption and the water of baptism, which three are one and remain distinct, and none of them is separated from union with the others. This is the faith by which the church lives and moves. — LETTERS 28

1 John 5:9

Bede: If we accept the testimony of man, the testimony of God is greater, etc. Great is the testimony of man that he gives concerning the Son of God, saying: “The Lord said to my Lord: Sit at my right hand” (Psalms 109). And from the person of the Son himself: “The Lord said to me: You are my Son” (Psalms 2). And likewise from the person of the Father speaking about the Son: “He will call upon me, ‘You are my Father, my God, and the rock of my salvation’” (Psalms 88). “My Father,” because I am the Son of God. “My God,” because I am man. “The rock of my salvation,” because I will suffer and be saved from death. “And I (he says) will make him my firstborn, the highest of the kings of the earth” (Ibid.). This is a great and true testimony, worthy of all acceptance. The testimony of man concerning the Son of God is great, but much greater is the testimony of God, who has testified himself about his Son when, speaking from heaven, he said: “You are my beloved Son, in whom I am well pleased” (Luke 3). Great is the testimony of the forerunner, who, bearing testimony about the Son of God, said: “I have baptized you with water, but he will baptize you with the Holy Spirit” (Matthew 3). Greater is the testimony of the Father, who sent the Holy Spirit upon him, whom he was always full of, even visibly. — Commentary on the Catholic Epistles

Hilary of Arles: The testimony of men refers to the testimony of people like Moses and the prophets, who were all men of God. — INTRODUCTORY COMMENTARY ON 1 JOHN

Oecumenius: If we receive the testimony of men, the testimony of God is greater: for this is the testimony of God, which he has testified of his Son. He who believes in the Son of God has the testimony in himself. He who does not believe God has made him a liar, because he does not believe the testimony that God has given of his Son. And this is the testimony, that God has given us eternal life: and this life is in his Son. He who has the Son has life; he who does not have the Son of God does not have life. Having said these things, he adds a persuasion of the things that are said, by a lesser argument, saying: If we receive the testimony of men about any common matter, ought we not to receive the testimony from God who is greater? Indeed, is not this testimony about His Son or Christ from God? Therefore, whoever believes in the Son of God, that He is God as the Son of God, has testimony in himself, that is, in himself, believing that he too has been adopted by God through Jesus, the adopted one. Whoever does not believe the truth is subject to two evils, namely disbelief, making God a liar: and furthermore depriving himself of adoption, and thus also of eternal life, which Christ has promised to those who would be adopted by Him: which he also has in himself as it is written in the Gospel: “In Him was life.” (Jn. 1:4) Therefore, whoever has the Son through holy baptism has life. For as many as we have been baptized into Christ, we have also, according to His command, put on Christ. But whoever does not have the Son of God through baptism does not have life, but is dead. For indeed, receiving the dead through sins, He awakens them through holy baptism. (Rom. 6:4) How? As it has often been said, that having been buried with Christ through the immersion that takes place in baptism, he is dead to the world (Gal. 6:14; Col. 2:20), or to worldly desires, and now lives not for himself, but for Christ (Gal. 2:20), walking according to His commandments in newness of life (Rom. 6:4), and no longer giving sin an opportunity to enter covertly. — Commentary on 1 John

1 John 5:10

Andreas of Caesarea: After giving us one testimony about his Son, God gave us another, which is eternal life. — CATENA

Bede: He who believes in the Son of God has the testimony of God in himself. He who thus believes in the Son of God, so as to practice in work what he believes, has the testimony of God in himself. Surely this is because he also may rightly be counted among the number of the sons of God, as the only Son of God promises to his faithful: “If anyone serves me, the Father will honor him” (John 12). If you have deserved to have the testimony of God, if you possess God as a witness of your unblemished faith, what does the infamy of men, what does even persecution harm you? For if God is for us, who can be against us? — Commentary on the Catholic Epistles

Bede: Whoever does not believe in the Son makes him a liar, etc. In vain the Jews and heretics think they believe in and venerate the Father, as long as they despise Christ and refuse to believe in him. For he who does not honor the Son does not honor the Father who sent him. Those who do not believe in the Son, who says “I and the Father are one” (John 10), and when Caiaphas asked, “Are you the Christ, the Son of the Blessed?” (Mark 14), he replied: “I am” (ibid.); but they argue that he is either not the Christ, or not the Son of God, or not similar to the Father, they certainly make the Father a liar, because they do not believe the testimony he has testified about his Son: namely, in what I mentioned before: “You are my beloved Son, in you I am well pleased” (Luke 3); and even in what he testified when the hour of passion was imminent, while he was praying and saying: “Father, save me from this hour, but for this cause I came to this hour. Father, glorify your name” (John 12), he responded, even the crowd hearing from heaven, “I have both glorified it and will glorify it again” (ibid.), truly signifying himself as God the Father in the heavens of him who, as a true man, was about to suffer death on earth. — Commentary on the Catholic Epistles

Hilary of Arles: God can never turn himself into a liar, because he is the essence of truth. But an unbelieving man is a liar, because he does not believe in the truth of God. — INTRODUCTORY COMMENTARY ON 1 JOHN

1 John 5:11

Bede: And this is the testimony, that God has given us eternal life. He said, He has given us eternal life. And he who speaks, still living a temporal life and subject to death in the flesh. But he has given us eternal life, just as he has given us the power to become children of God to those who believe in his name. For to know that the power to have eternal life has been given by God, listen to the prophet: “Who is the man who desires life, and loves many days, that he may see good? Keep your tongue from evil, and your lips from speaking deceit,” and so on to the end of the psalm (Psalms 33). Therefore he has given us eternal life, but still to those wandering on earth in hope, which he will give in heaven to those who arrive to him in reality. — Commentary on the Catholic Epistles

Bede: And this life is in His Son. Namely, in the faith and confession of His name, in the reception of His sacraments, in the observance of His commandments. Hence He Himself also said: No one comes to the Father except through Me (John XIV). And Peter about Him: Nor is there salvation in any other, for there is no other name under heaven given among men by which we must be saved (Acts IV). — Commentary on the Catholic Epistles

Shepherd of Hermas: Accordingly, those also who fell asleep received the seal of the Son of God. For before a man bears the name of the Son of God he is dead; but when he receives the seal he lays aside his deadness, and obtains life. The seal, then, is the water: they descend into the water dead, and they arise alive. — Shepherd of Hermas, Similitude 9

1 John 5:12

Augustine of Hippo: Here John testifies that no one has life unless he has Christ. — AGAINST JULIAN 6.9.27

Bede: He who has the Son, has life, etc. So that it may not seem too little to say that life is in the Son, he added that the Son Himself is life. Which the Son, glorifying the Father, also showed when He said: For as the Father has life in Himself, so He has granted the Son to have life in Himself (John V). But how the same life which is common to both the Son and the Father also enlightens believers, the same Son elsewhere intimates in prayer to the Father: As You have given Him authority over all flesh, that He should give eternal life to as many as You have given Him. This is eternal life, that they may know You, the only true God, and Jesus Christ whom You have sent (John XVII). — Commentary on the Catholic Epistles

Tertullian: We believe not the testimony of God in which He testifies to us of His Son. “He that hath not the Son, hath not life.” And that man has not the Son, who believes Him to be any other than the Son. — Against Praxeas

1 John 5:13

Bede: These things I have written to you, that you may know that you have eternal life, etc. That you may know, he says, that you may be certain of your future blessedness, who believe in Christ, so that you are not deceived by the fraud of those who deny that Jesus is the Son of God, and therefore assert that nothing will benefit those who have believed in His name. And the wondrous madness of heretics, who, though the Son of God is referred to throughout this entire Epistle, still assert that Christ is not the Son but a creature of God. Which in no way do they read, except when His humanity is mentioned. — Commentary on the Catholic Epistles

Oecumenius: I have written these things to you who believe in the name of the Son of God: that you may know that you have eternal life, and that you may believe in the name of the Son of God. And this is the confidence that we have in Him, that if we ask anything according to His will, He hears us. And if we know that He hears us in whatever we ask, we know that we have the requests that we have asked of Him. As if in a summary at the end, John repeats the aforementioned and says: I have written these things to you as heirs of eternal life: for these things would not be written for those who do not live according to the hope of eternal life: because neither should holy things be given to dogs nor pearls be scattered before pigs, (Matt. 7:6) for they do not deserve praise. Therefore, writing these things as heirs of eternal life, John briefly repeats, as we have said, suggesting to them what has already been said: first, that it is necessary to firmly believe in the name of the Son of God, that is, in the divine worship handed down to us by Him: for this is what the name of the Son of God signifies, as we have said, to whom, namely, the grace of sacred baptism prepares the way. Then, since there is no other sign of this unquestionable faith except trust, which we find in Him through irreproachable faith, as we have also said before. Again, He has set a sign of this trust, that we are not to be frustrated in all that is asked of us. But since not everyone achieves all that they ask for, nor are they always heard in what they request, He adds: according to His will: revealing indeed that the one asking, outside the will of the Master, is not to be heard, in accordance with blessed James: for he also said, “You ask and do not receive, because you ask with wrong motives,” (James 4:3) that is, as it does not benefit you. However, converting this sign into a clearer indication, John says: “And if we know that He hears us in whatever we ask, we know that we have the requests that we have asked of Him:” saying something like this: If we ask according to His will, He hears us: and if He hears us in whatever we ask, we know that we make our requests according to His will, and we have in ourselves the requests that we have asked. These, however, are His kingdom and righteousness (Matt. 6:33): which He also commanded us to ask for. Having said this, He also clearly proposes something of what He wants us to ask according to God’s will. For the entire letter is largely about extolling love for the brother and expressing the desire that we keep our love for the brother incorrupt, John now says that this is one of his wills, that “if anyone sees his brother sinning not unto death, he should ask, and it will be given to him.” (1 Jn. 5:16) And what will be given? “Eternal life.” To whom? To those who “sin not unto death.” — Commentary on 1 John

1 John 5:14

Bede: And this is the confidence that we have toward him, etc. He provides us with great confidence to hope for heavenly goods from the Lord, because even in this life, whatever we ask of him in a salutary manner, we obtain, according to what he himself promises believers in the Gospel: “I say to you, whatever you ask in prayer, believe that you have received it, and it will be yours” (Mark XI). But it must be noted that we are heard by the Lord when praying in such a way, provided we ask for what he has commanded. He himself says, “Seek first the kingdom of God and his righteousness” (Matthew VI). Hence, John rightly interposed after saying, “Whatever we ask, we receive from him,” by adding, “according to his will.” Therefore, we are commanded to have full and undoubted confidence of being heard only regarding those things which align not with our own benefits or temporal comforts but with the Lord’s will. This is also to be included in the Lord’s Prayer: “Your will be done” (Matthew VI), that is, not ours. For if we remember the Apostle’s words: “For we do not know what to pray for as we ought” (Romans VIII), we understand that sometimes we ask for things contrary to our own salvation, and it is most beneficial for us that those things we ask are denied by him who perceives our benefit more rightly than we do. This undoubtedly happened even to the teacher of the Gentiles himself. — Commentary on the Catholic Epistles

Clement of Alexandria ((as quoted by Cassiodorus)): “And this is the confidence which we have towards Him, that if we ask anything according to His will, He will hear us.” He does not say absolutely what we shall ask, but what we ought to ask. — From the Latin Translation of Cassiodorus

Didymus the Blind: Those who possess technical skills and know how to repair things are fully confident that when the need arises they will be able to do so. Similarly these holy men, John and the other apostles, knew from their own experience that if they asked God for what was pleasing and acceptable to him, they would obtain it. For God is most generous to those who have this knowledge and will grant the requests of those who ask according to his will. — COMMENTARY ON 1 JOHN

1 John 5:15

Bede: And we know that he hears us in whatever we ask, etc. He repeatedly emphasizes the same points previously stated, to encourage us to pray more energetically. But the objection remains that we should ask according to the will of our Creator. This can be understood in two ways: both that we ask for those things he desires, and that we come to petition him in the manner he desires us to be. This means to have faith that works through love (Galatians V), and above all, to remember that gospel command: “And whenever you stand praying, forgive if you have anything against anyone, so that your Father who is in heaven may forgive you your trespasses” (Mark XI). — Commentary on the Catholic Epistles

1 John 5:16

Andreas of Caesarea: It is the sin of heresy, or of blasphemy against the Holy Spirit, which leads to death. If one man sins against another, pray for him. But if he sins against God, who is there who can pray on his behalf? — CATENA

Augustine of Hippo: Even though the Lord commands us to pray for our very persecutors, this passage clearly shows that there are some brothers for whom we are not commanded to pray. We therefore must acknowledge that there are some sins among the brothers which are worse than persecution by enemies. I think that the sin of a brother is unto death when anyone who has attained a knowledge of God through the grace of our Lord Jesus Christ opposes the brotherhood and is aroused by the fires of envy against that very grace by which he was reconciled to God. — COMMENTARY ON THE SERMON ON THE MOUNT 1.22.73

Augustine of Hippo: In another place I defined the sin of a brother unto death [see above], but I should have added: “if he ends this life in a perversity of mind as wicked as this.” For surely we must not despair of anyone, no matter how wicked he is, while he lives, and we should pray with confidence for him of whom we should not despair. — RETRACTATIONS 1.18.7

Augustine of Hippo: But what presses harder upon the present question is that saying of the apostle John, “If any man know that his brother sinneth a sin not unto death, he shall ask, and the Lord will give life to that man who sinneth not unto death: but there is a sin unto death: not for that do I say that he should ask.” For it manifestly shows that there are some “brethren” whom we are not commanded to pray for, whereas the Lord bids us pray even for our persecutors. Nor can this question be solved except we acknowledge, that there are some sins in brethren that are worse than the sin of enemies in persecuting. — Ten Homilies on 1 John 10

Augustine of Hippo: The “sin,” therefore, of a brother, “unto death,” I suppose to be when, after the acknowledging of God through the grace of our Lord Jesus Christ, one fights against the brotherhood, and is set on by the fire-brands of hatred against the very grace through which he was reconciled to God. But “a sin not unto death” is when a person, not having alienated his love from his brother, yet through some infirmity of mind may have failed to exhibit the due offices of brotherhood. Wherefore, on the one hand, the Lord on the cross said, “Father, forgive them, for they know not what they do,” since they had not yet, by being made partakers of the grace of the Holy Spirit, entered into the fellowship of holy brotherhood; and blessed Stephen in the Acts of the Apostles prays for them who are stoning him; because they had not yet believed Christ, and were not fighting against that grace of communion. On the other hand, the apostle Paul does not pray for Alexander, and the reason I suppose, is, that this man was a brother, and had sinned “unto death,” i.e. by opposing the brotherhood in a spirit of hatred. — Ten Homilies on 1 John 10

Augustine of Hippo: This difference of sins it is that distinguishes Judas with his treason from Peter with his denial. Not that to him who repenteth there is to be no forgiveness: lest we go against that sentence of the Lord, in which He commands always to forgive the brother who asks his brother’s forgiveness: but that the mischief of that sin is, that the man cannot submit to the humiliation of begging for pardon, even when he is forced by his evil conscience both to acknowledge and to publish his sin. For when Judas had said, “I have sinned, in that I have betrayed the innocent blood,” he went and hanged himself in desperation, rather than pray for forgiveness in humiliation. Wherefore it makes a great difference, what sort of repentance God forgives. For many are much quicker than others to confess that they have sinned, and are angry with themselves in such sort that they vehemently wish they had not sinned, while yet they cannot lay down their pride, and submit to have the heart humbled and broken so as to implore pardon: a state of mind which one may well believe to be, for the greatness of their sin, a part of their already begun damnation. — Ten Homilies on 1 John 10

Augustine of Hippo: And this, perhaps, it is “to sin against the Holy Ghost:” i.e. through malice and envy to fight against brotherly charity after receiving the grace of the Holy Spirit: that sin which the Lord saith hath no forgiveness, either here or in the world to come. For the Lord in saying to the Pharisees, “Whosoever shall speak an evil word against the Son of Man,” may have meant to warn them to come to the grace of God, and having received it, not to sin as they have now sinned. For now they have spoken an evil word against the Son of Man, and it may be forgiven them, if they be converted and believe and receive the Holy Spirit: which when they have received, if they will then have ill-will against the brotherhood and oppose the grace they have received, there is no forgiveness for them, either in this world or in the world to come. — Ten Homilies on 1 John 10

Augustine of Hippo: By this grace such is the liberty they receive, that although as long as they live here they have to fight against the lusts of sins, and are overtaken by some sins for which they must daily pray, “Forgive us our debts,” yet they no longer serve the sin which is unto death, of which the apostle John saith, “There is a sin unto death, I do not say that he shall ask for that.” Concerning which sin (since it is not expressed) many different opinions may be formed: but I affirm that sin to be the forsaking until death the “faith which worketh by love.” — Ten Homilies on 1 John 10

Bede: Just as Christ washes us from our sins by interceding with the Father on our behalf, so also should we, if we know that our brother is committing a sin which is “not unto death.” — Homilies on the Gospels 2.5

Bede: Who knows his brother to sin a sin not unto death, etc. These and such things are asked according to the will of the Lord, which pertain to the duty of brotherly love. He speaks, however, of daily and light sins, which as they are difficult to avoid, so also are easily cured. But regarding the manner in which this mutual request should be carried out for sins, James more clearly indicates, saying: Confess your sins to one another, and pray for one another that you may be saved (James V). If, therefore, by speaking, or thinking, or forgetfulness, or ignorance you have perhaps erred, go to your brother, confess to him, ask for intervention. If he purely confesses to you, making you aware of his own frailty, and you piously intercede for his errors, correct him. But these things are said about lighter sins. Moreover, if you have committed something more serious, bring in the elders of the Church, and at their examination, punish yourself. — Commentary on the Catholic Epistles

Bede: There is a sin unto death, etc. A great question arises here, because blessed John clearly shows that there are certain brothers for whom we are not instructed to pray, whereas the Lord even commands us to pray for our persecutors. This can only be resolved by admitting that there are some sins among the brothers which are more grievous than the persecution by enemies. Therefore, the sin of a brother unto death occurs when, after the knowledge of God, which is given through the grace of our Lord Jesus Christ, someone attacks the brotherhood and is inflamed with envy against the very grace by which they were reconciled to God. However, a sin not unto death is if someone has not withdrawn love from their brother but has not shown the duties owed to brotherhood due to some weakness of mind. Therefore, the Lord on the cross says: Father, forgive them, for they do not know what they are doing (Luke 23). For they had not yet become participants in the grace of the Holy Spirit, nor had they entered the communion of holy brotherhood. And blessed Stephen prays for those by whom he was being stoned because they did not yet believe in Christ, nor did they fight against that common grace. And the apostle Paul, for this reason, I believe, does not pray for Alexander because he was already a brother; and he had sinned unto death, that is, by attacking brotherhood with envy. But he prays that those who had not severed love but had succumbed to fear be forgiven. For he thus says: Alexander the coppersmith did me much evil; the Lord will repay him according to his works; whom do you also avoid, for he has greatly resisted our words (2 Tim. 4). Then he adds for whom he prays, saying: At my first defense, no one stood with me, but all forsook me; may it not be charged against them (Ibid.). However, a sin unto death can be understood as one for which someone is forbidden to pray, because a sin that is not corrected in this life, its forgiveness is sought in vain after death. But if we carefully inspect the following, the previous sense of this reading seems to align more with its tenor. For it continues: — Commentary on the Catholic Epistles

Clement of Alexandria: John, too, manifestly teaches the differences of sins, in his larger Epistle, in these words: “If any man see his brother sin a sin that is not unto death, he shall ask, and he shall give him life: for these that sin not unto death,” he says. For “there is a sin unto death: I do not say that one is to pray for it. All unrighteousness is sin; and there is a sin not unto death.” — The Stromata Book 2

Cyprian: Of this same thing in the first book of Kings: “If a man sin by offending against a man, they shall pray the Lord for him; but if a man sin against God, who shall pray for him? " — Treatise XII Three Books of Testimonies Against the Jews

Oecumenius: If anyone sees his brother sinning a sin not leading to death, he will ask, and He will give him life for those who commit sin not leading to death. There is sin leading to death; I do not say that he should pray about that. All unrighteousness is sin, and there is sin not leading to death. “If anyone sees his brother sinning.” This is one will. For it is righteous to feel compassion for the brother who has sinned and to be of help for salvation. “There is a sin leading to death.” Let this be the order: There is a sin that leads to death, and there is a sin that does not lead to death. I do not say that one should pray for the one that leads to death, but for the one that does not lead to death. Then he explains the distinction making between the sin that leads to death and the one that does not lead to death. For John simply divides it as a kind of sin and says: All unrighteousness is sin: whether it leads to death or does not lead to death. But because it is unto death, let him not pray or ask, for he will not be heard because he asks with wrong motives (James 4:3), especially when he shows no sign of conversion. For this alone is the sin that leads death, which does not regard repentance: when Judas fell ill with this, he was taken to eternal death. And those also sin that leads death who are mindful of injuries. For the paths of those who remember injuries lead to death (Prov. 12:28 LXX.), says Solomon. Nor do they convert by remembering, retaining the memory of injuries, and keeping anger against their neighbor, but they sin without repentance. — Commentary on 1 John

Origen of Alexandria: Since there are sins “unto death,” it follows that anyone who commits one of them will die as a result. — SERMONS ON Leviticus 11.2.6

Tertullian: Touching this difference, we have not only already premised certain antithetical passages of the Scriptures, on one hand retaining, on the other remitting, sins; but John, too, will teach us: “If any knoweth his brother to be sinning a sin not unto death, he shall request, and life shall be given to him; “because he is not “sinning unto death,” this will be remissible. “(There) is a sin unto death; not for this do I say that any is to request” -this will be irremissible. — On Modesty

Tertullian: For (in making these assertions) he was looking forward to the final clause of his letter, and for that (final clause) he was laying his preliminary bases; intending to say, in the end, more manifestly: “If any knoweth his brother to be sinning a sin not unto death, he shall make request, and the Lord shall give life to him who sinneth not unto death. For there is a sin unto death: not concerning that do I say that one should make request.” He, too, (as I have been), was mindful that Jeremiah had been prohibited by God to deprecate (Him) on behalf of a people which was committing mortal sins. — On Modesty

1 John 5:17

Bede: All iniquity is sin, etc. Such is the diversity of sins, he says, that everything which deviates from the rule of equity is counted among the sins, although small sins cannot in any way take away or diminish the merit of righteousness from the just, as long as they are those without which this life cannot be lived, and likewise there are certain sins so discordant with all justice, committed with such iniquity, that without any contradiction, unless they are corrected, they lead their perpetrator to eternal punishment. Concerning which it is written: The soul that sins shall die (Ezekiel 18). Blessed John’s statement clearly repudiates the inept argument of the Stoics, who dared to say against all human sense and to affirm that all sins are equal, saying it makes no difference whether a man steals a human being, an ox, or a chicken, because it is not the animal but the intention that constitutes the crime. Jovinian the heretic followed them, asserting that there is no distinction between marriage and virginity, claiming that those who abstain in no way should be preferred in any privilege of recompense over those who simply partake in feasting. Therefore, everything that is unjustly committed or thought is to be referred to as sin. But there are some sins unto death, about which the Apostle says: For those who do such things shall not inherit the kingdom of God (Galatians 5). — Commentary on the Catholic Epistles

1 John 5:18

Andreas of Caesarea: It may be true that the righteous person does not sin, but no one is a child of God by nature. This is why we avoid sin, not by the way in which we were made, which would make sin impossible for us, but by watching out that we do not fall into it. — CATENA

Bede: We know that everyone who is born of God does not sin. Sin, namely unto death. This can be understood about all mortal crimes, and specifically that which violates brotherhood, as we have explained above. But also, the sin unto death can be said to be rightly understood as the sin prolonged up to the time of death, which everyone born of God does not commit. After all, King David committed a mortal crime. For who does not know that adultery and murder deserve eternal death? But yet David, because he was born of God, because he belonged to the society of the children of God, he did not sin unto death, because he immediately obtained forgiveness for his guilt by repenting. — Commentary on the Catholic Epistles

Bede: But the generation of God preserves him, etc. The grace of Christ, by which the faithful are reborn, preserves those who are called holy according to the purpose, so that they do not commit sin leading to death; and if they err in anything due to the frailty of human condition, it protects them from being touched by the malignant enemy. Furthermore, it must be said, we remain in the generation of God as long as we do not sin; indeed, those who persevere in the generation of God cannot sin, nor be touched by the malignant. For what communion has light with darkness, Christ with Belial (II Cor. VI)? Just as (he says) day and night cannot be mixed, so righteousness and iniquity, sin and good works, Christ and Antichrist, the malignant one and the generation of God. — Commentary on the Catholic Epistles

Bede: We know that we are born of God, etc. We are of God, regenerated by His grace and baptism through faith, and saved so that we may endure in faith. However, the lovers of the world are subjected to the enemy, either never freed from his dominion by the wave of regeneration, or after the grace of regeneration, returned again to his dominion by sinning. Not only the lovers of the world but also those who are recently born and do not yet have discernment of good and evil, because of the guilt of the first violation, belong to the kingdom of the evil enemy unless by the grace of the kind Creator they are rescued from the power of darkness and transferred into the kingdom of the Son of His love (Colossians 1). Hence, he did not simply say that the world is in the evil one but added, And (he says) the whole world is placed in the evil one. For as blessed Ambrose says: “We are all born under sin, whose very birth is in defect.” And Pelagius strives in vain to affirm that infants recently born have no need of the grace of baptism to be reborn, because they are said to be born as clean from all stain of sin as Adam was created in paradise, deriving no stain of original guilt from him, and being guilty of nothing until they begin to sin by their own will. But as for us, setting aside the poisons of the Antichrists, which are condemned and expelled from the Church all through this Epistle by the one who drank from the breast of the Lord, the fountain of life, let us hear in the closure the good word of salvation which he pours out for us. Let us observe the works of the supreme King which he tells of. The following ensues: — Commentary on the Catholic Epistles

Didymus the Blind: If it is true that when someone does what is righteous his power to do so comes from God, and if it is also true that righteousness and evil cannot live together, then it is perfectly clear that as long as a person does such things he is righteous and does not sin. But because this ability is given by grace and is not natural, John adds that the righteous person must watch out, so that evil will not touch him. — COMMENTARY ON 1 JOHN

Oecumenius: We know that whoever is born of God does not sin, but he who has been born of God guards (τηρεῖ) himself, and the wicked one does not touch him. We know that we are of God, and the whole world lies under the sway of the wicked one. And we know that the Son of God has come and has given us an understanding, that we may know Him who is true; and we are in Him who is true, in His Son Jesus Christ. This is the true God and eternal life. Little children, keep yourselves from idols. Amen. Having declared this, he subsequently indicates whose sin is the sin leads to death; and he says that whoever is born of God does not sin. For when he has once entrusted himself to the one dwelling in him through adoption in Christ, he remains inaccessible to sin. However, lest anyone think that such a nature has been completely changed, so that he can no longer be seized by sin, he adds: “He guards himself,” as if to say: Unless he were to keep and guard himself from the evil one, he would certainly sin. Therefore, it is not nature that leads to perfection, but rather the glory of God, who, because He has adopted us, has deemed us worthy of such grace: that by keeping and guarding what has been given to us by Him, we may also have it, so that we do not sin. For unless it were so, since the world is established in evil (and the world refers to those who have not committed themselves to God through good works), nothing would prevent us from being examined along with those who perish: because the mind of man is continually inclined to evil from early youth, as God revealed during the time of the flood. (Gen. 8:22) But since, John says, the Son of God has come and has given us an understanding by which we may know the true God through internal understanding, and be in His true Son Jesus Christ: we have come to know through this glory that He is the true God and eternal life, and by knowing we are safe from the onslaught of evil and its offenses. “This is the true God.” This, also, serves as a demonstrative article. Here, the article indicates relationship. “keep yourself from idols.” Some have questioned: If John writes this to the perfect, why does he now command them to beware of idols? We therefore say that because he wrote to the whole Church, which was not made up of a select people, but there were also some among them who were less affected. Therefore, he commands all these, looking at their slippery nature. — Commentary on 1 John

Tertullian: Chapter V.-Sin Never to Be Returned to After Repentance. — On Repentance

1 John 5:19

Clement of Alexandria ((as quoted by Cassiodorus)): “And the whole word lies in the wicked one;” not the creation, but worldly men, and those who live according to their lusts. — From the Latin Translation of Cassiodorus

Didymus the Blind: The “world,” that is, those who love the world, are subjected to evil. This includes everybody, because we are all born under sin, which traces its origin to the disobedience of Adam. Many heretics claim that there is a creator god who made the world evil to begin with, but this is not so. The word refers to people, not to the material substance of creation. — COMMENTARY ON 1 JOHN

Dionysius of Alexandria: For in the most general sense it holds good that it is apparently not possible for any man to remain altogether without experience of ill. For, as one says, “the whole world lieth in wickedness;” and again, “The most of the days of man are labour and trouble.” But you will perhaps say, What difference is there between being tempted, and falling or entering into temptation? Well, if one is overcome of evil-and he will be overcome unless he struggles against it himself, and unless God protects him with His shield-that man has entered into temptation, and is in it, and is brought under it like one that is led captive. But if one withstands and endures, that man is indeed tempted; but he has not entered into temptation, or fallen into it. — The Gospel According to Luke

Ishodad of Merv: The world is subjected to the perversion which gives birth to sin, and because of that it is prone to the cultivation of evil things. — COMMENTARIES

Jerome: [Daniel 4:4] “I, Nebuchadnezzar, was at ease in my house and prospering in my palace.” The narrative is clear indeed and requires but little interpretation. Because he displeased God, Nebuchadnezzar was turned into a madman and dwelt for seven years amongst the brute beasts and was fed upon the roots of herbs, Afterwards by the mercy of God he was restored to his throne, and praised and glorified the King of heaven, on the ground that all His works are truth and His ways are justice and He is able to abase those who walk in pride. But there are some who claim to understand by the figure of Nebuchadnezzar the hostile power which the Lord speaks of in the Gospel, saying: “I beheld Satan falling from heaven like lightning” (Luke 10:18). Likewise John in Revelation, in the passage where the dragon falls upon the earth drawing a third of the stars with him (Revelation 12:4). Likewise Isaiah: “How hath the morning star fallen, which used to rise early in the morning” (Isaiah 14:12). These authorities assert that it was absolutely impossible for a man who was reared in luxury to subsist on hay for seven years and to dwell among wild beasts for seven years without being at all mangled by them. Also they ask how the imperial authority could have been kept waiting for a mere madman, and how so mighty a kingdom could have gone without a king for so long a period. If, on the other hand, anyone had succeeded him on the throne, how foolish he would have to be thought to surrender an imperial authority which he had possessed for so long. Such a thing would be especially incredible since the historical records of the Chaldeans contain no such record, and since they recorded matters of far less import, it is impossible that they should have left things of major importance unmentioned. And so they pose all of these questions and offer as their own reply the proposition that since the episode does not stand up as genuine history, the figure of Nebuchadnezzar represents the devil. To this position we make not the slightest concession; otherwise everything we read in Scripture may appear to be imperfect representations and mere fables. For once men have lost their reason, who would not perceive them to lead their existence like brutish animals in the open fields and forest regions? And to pass over all other considerations, since Greek and Roman history offer episodes far more incredible, such as Scylla and the Chimaera, the Hydra and the Centaurs, and the birds and wild beasts and flowers and trees, the stars and the stones into which men are related to have been transformed, what is so remarkable about the execution of such a divine judgment as this for the manifestation of God’s power and the humbling of the pride of kings? Nebuchadnezzar says, “‘I was at ease in my house and prospering in my palace…’” or as Theodo-tion renders it “upon my throne.” Now those who follow the interpretation we are opposing understand by the devil’s home this world of ours. Concerning the world Satan himself in the Gospel says to the Savior: “All these things have been given over to me” (Luke 4:6). Likewise the Apostle says: “The world lieth in the Wicked One” (1 John 5:19). — St. Jerome, Commentary on Daniel, CHAPTER FOUR

Methodius of Olympus: “As then, when the days of our present life shall fail, those good deeds of beneficence to which we have attained in this unrighteous life, and in this “world “which “lieth in wickedness”

1 John 5:20

Andreas of Caesarea: Even at the end of his letter, John never stops insisting on the need for right doctrine. We have been given understanding to the extent that we have known the Son of God, who really has come into the world. This is what it means to say that “we have the mind of Christ.” The person who has this mind and understanding knows what is really true and is united with him because he shares the same mind. — CATENA

Augustine of Hippo: When ye read, “That we may be in His true Son Jesus Christ,” think of the “true Son” of God. But this Son ye in no wise think to be the true Son of God, if ye deny Him to be begotten of the substance of the Father. For was He already Son of Man and by gift of God became Son of God, begotten indeed of God, but by grace, not by nature? Or, though not Son of Man, yet was He some sort of creature which, by God’s changing it, was converted into Son of God? If you mean nothing of this sort, then was He either begotten of nothing, or of some substance. But thou hast relieved us from all fear of having to suppose that you affirm the Son of God to be of nothing, for thou hast declared that this is not your meaning. Therefore, He is of some substance. If not of the substance of the Father, then of what? Tell me. But ye cannot find any other. Consequently, the Father and the Son are of one and the same substance. This is the Homousion. — Ten Homilies on 1 John 10

Augustine of Hippo: In the Scriptures both you and We read, “That we may be in His true Son Jesus Christ; He is the true God and Eternal Life.” Let both parties yield to such weighty evidence. Tell us then, whether this “true Son” of God, discriminated as He is by the property of this name from those who are sons by grace, be of no substance or of some substance. Thou sayest, “I do not say that He is of no substance, lest I should say that He is of nothing.” He is therefore of some substance: I ask, of what? If not of the substance of the Father, seek another. If thou findest not another, as indeed thou canst find none at all, then acknowledge it to be the Father’s, and confess the Son Homousios, “of one substance with the Father.” — Ten Homilies on 1 John 10

Augustine of Hippo: Flesh is begotten of flesh, the Son of flesh is begotten of the substance of the flesh. Set aside corruption, reject from the eye of the mind all carnal passions, and behold “the invisible things of God understood by the means of the things that are made.” Believe that the Creator who hath given flesh power to beget flesh, who hath given parents power of the substance of the flesh to generate “true sons” of flesh, much more had power to beget a “true Son” of His own substance, and to have one substance with the true Son, the spiritual incorruption remaining and carnal corruption being altogether alien therefrom. — Ten Homilies on 1 John 10

Augustine of Hippo: If He is begotten, He is Son: if He is Son, He is the “true Son,” because Only-Begotten. For we also are called sons: He Son by nature, we sons by grace. To say that because He is begotten, He is of another nature, is to deny that He is the “true Son.” Now we have the Scripture: “That we may be in His true Son Jesus Christ; He is the true God and Eternal Life.” Why “true God”? because “true Son” of God. For if He has given to animals this property, that what they beget shall be none other than what they themselves are: man begets man, dog begets dog, and should God not beget God? If then He is of the same substance, why callest thou Him less? — Ten Homilies on 1 John 10

Augustine of Hippo: Is it because when a human father begets a son, though human beget human, yet greater begets less? If so, then let us wait for Christ to grow as human beings grow whom human beings beget! But if Christ, ever since He was begotten (and this was not in time but from eternity), is what He is, and yet is less than the Father, at that rate the human condition is the better of the two: for a human being at any rate can grow, and has the property of sooner or later attaining to the age, to the strength of the father; but He never: then how is He a “true Son”? — Ten Homilies on 1 John 10

Augustine of Hippo: And if the Son be not of the same substance as the Father, then is He a made substance: if a made substance, then not “all things were made by Him:” but, “all things were made by Him;” therefore, He is of one and the same substance with the Father. And therefore, not only God, but True (or, Very) God. Which the same John doth most openly affirm in his epistle: “We know that the Son of God is come; and hath given us an understanding that we may learn to know the True God, and may be in His true Son Jesus Christ. This is the True God and Eternal Life.” — Ten Homilies on 1 John 10

Augustine of Hippo: Hence also by consequence we understand, that what the apostle Paul saith, “Who only hath immortality,” he saith not merely of the Father, but of the One and Only God, which the Trinity itself is. For neither is the “Eternal Life” itself mortal in respect of any mutability: and consequently, since the Son of God “is Eternal Life,” He also is to be understood together with the Father, where it is said, “Who only hath immortality.” — Ten Homilies on 1 John 10

Bede: And we know that the Son of God has come, etc. For what could be clearer than these words? What could be sweeter? What could be said more strongly against all heresies? Christ is the true Son of God. The Father of Christ Jesus our Lord is the true God. The eternal Son of God came temporally into the world, who was in the world, and through whom the world was made. Nor did He come for any other reason than for our salvation, that is, to give us the understanding to know the true God. For no one could come to life without divine knowledge, no one could know God except by His teaching: as He Himself says: And no one knows the Son except the Father, nor does anyone know the Father except the Son, and whom the Son wills to reveal Him (Luke X). It is implied: both the Father and the Son. For the Son reveals both, who, appearing visibly in the flesh, has deigned to now reveal the secrets of divinity through His Gospel. — Commentary on the Catholic Epistles

Bede: This is the true God, and eternal life. He had said that the Son is the true God, and repeatedly affirms that this one is the true God. He says that this one is eternal life. Not in the way eternal life is promised to us, which takes us from time and places us so that we never cease living well; but the Son is life, always remaining without the beginning of time, always remaining without end. — Commentary on the Catholic Epistles

Clement of Alexandria ((as quoted by Cassiodorus)): “And the Son of God has come and given us understanding,” which comes to us, that is, by faith, and is also called the Holy Spirit. — From the Latin Translation of Cassiodorus

Didymus the Blind: The understanding which God gave, by which it is known that the true Son of God is coming, is the same as the mind of Christ. — COMMENTARY ON 1 JOHN

1 John 5:21

Bede: Little children, keep yourselves from idols. You who have known the true God, in whom you have eternal life, keep yourselves from the doctrines of heretics, which lead to eternal death, because, like those who make idols in place of God, they change the glory of the incorruptible God into the likeness of corruptible things with perverse teachings (Rom. I). Keep yourselves from love of money, which is the service of idols. Be careful not to prefer any worldly allurements over the love of the Creator. For this too will be counted among idols, so that having the care and diligence for truth alone, you may deserve to rejoice endlessly in its vision. For the world passes away, and its desire. But whoever does the will of the Lord remains forever (1 John II). — Commentary on the Catholic Epistles

Didymus the Blind: Why is it that after everything else which he has said to his hearers during the course of his letter, John should keep this warning about idols to the very end? In my opinion it is because here he is addressing the church in general. There must have been many in that assembly who were former idolaters, and he adds this caution for their benefit. — CATENA

Hilary of Arles: The letter ends as it began, with an admonition to worship the one true God alone. Everything else that John says is contained in this one golden rule. — INTRODUCTORY COMMENTARY ON 1 JOHN

Tertullian: John did not tell us to keep away from worship, but from idols, that is, from their very likeness. For it is wrong for you, who are created in the image of the living God, to become the image of an idol and a dead man. — ON THE CROWN 5.10

Tertullian: Even an earthly serpent sucks in men at some distance with its breath. Going still further, John says, “My little children, keep yourselves from idols,” -not now from idolatry, as if from the service of it, but from idols-that is, from any resemblance to them: for it is an unworthy thing that you, the image of the living God, should become the likeness of an idol and a dead man. — De Corona
