Names (3687) (onomazo from onoma = name) means to give a name, to assign an appellation, pronounce a name (as in exorcism - Acts 19:13) or make mention of (Eph 5:3), bear the name of (in this case of the Lord). Onomazo means to be known or to name in worship in Ro 15:20. The sense of onomazo in 2Ti 2:19 is to profess. To make mention of the name of Jehovah in praise, which is true of His worshippers (Is. 26:13; Am. 6:10). Wuest says onomazo in 2Ti 2:19 means... to pronounce a name as having a special virtue, to utter a name as acknowledging and appropriating what the name involves, as a confession of faith and allegiance. Marvin Vincent writes that onomazo... means to give a name to, to style, as Mk. 3:14; L. 6:14; 1 Cor. 5:11: to pronounce a name as having a special virtue, as in incantation, as Acts 19:13: to utter a name as acknowledging and appropriating what the name involves, as a confession of faith and allegiance. So here (2Ti 2:19). Onomazo is in the present tense depicts these individuals as continually naming the name of the Lord Jesus Christ...some may name Him one day or for a season, only to fall away when persecution arises or they are choked by the worries, pleasures and riches of the world (Mk 4:19, Lk 8:14). A true follower of Christ will never (irrevocably) deny His Name. Stated another way, the one who names Christ continually is the one who does not deny Him. Eugene Minor says that in 2Ti 2:19, onomazo is... part of an idiom ‘to name’ [BAGD, Herm, HNTC, Lns, NTC; KJV, NASB], ‘to profess’ [NAB], ‘to confess’ [NIV], ‘to call on’ [NJB, NRSV], ‘to take upon his lips’ [REB], ‘to speak’ [TNT]. The idiom ‘to name the name of the Lord’ is translated ‘to say that one belongs to the Lord’ [LN; TEV], ‘to worship the Lord’ [ICC], ‘to declare that one is a worshiper of the Lord’ [LN]....This defines who the Lord’s true people are, since they reveal that they belong to him by forsaking unrighteousness (An Exegetical Summary of 2 Timothy) Bietenhard writes that It is a common belief of antiquity that the name is not just a label but part of the personality of the one who bears it. (Kittel, G., Friedrich, G., & Bromiley, G. W. Theological Dictionary of the New Testament. Eerdmans or Wordsearch) Onomazo - 10x in the NAS and translated as - derives its name(1), name(1), named(5), names(1), so-called(1). Mark 3:14 And He appointed twelve, so that they would be with Him and that He could send them out to preach, Luke 6:13 And when day came, He called His disciples to Him and chose twelve of them, whom He also named as apostles: 14 Simon, whom He also named Peter, and Andrew his brother; and James and John; and Philip and Bartholomew; Acts 19:13 But also some of the Jewish exorcists, who went from place to place, attempted to name over those who had the evil spirits the name of the Lord Jesus, saying, "I adjure you by Jesus whom Paul preaches." Romans 15:20-note And thus I aspired to preach the gospel, not where Christ was already named, so that I would not build on another man's foundation; 1 Corinthians 5:11 But actually, I wrote to you not to associate with any so-called (one who goes by the name of, who claims to be, who calls oneself) brother if he is an immoral person, or covetous, or an idolater, or a reviler, or a drunkard, or a swindler-- not even to eat with such a one. MacArthur comments: It is the so—called [onomazo, “to bear the name of”] brother who is a threat to the spiritual welfare of a church and with whom we are not to associate. We cannot know who is and is not a true believer, but discipline is to be administered to any who professes to be a Christian. Since we cannot tell the difference, tares must be treated like wheat. Anyone who carries the name of Christ is subject to discipline. Paul makes it clear that excommunication is not limited only to cases of extreme sin such as that of the incestuous brother who was living with his stepmother. It should be applied to any professing believer who is an immoral person, or covetous, or an idolater, or a reviler, or a drunkard, or a swindler. (MacArthur, J: 1Corinthians. Chicago: Moody Press or Logos or Wordsearch) Ephesians 1:21-note far above all rule and authority and power and dominion, and every name that is named, not only in this age but also in the one to come. Ephesians 3:15-note from whom every family in heaven and on earth derives its name, Ephesians 5:3-note But immorality or any impurity or greed must not even be named (be mentioned, be spoken about, "there must not be even a hint among you" = NIV)(present imperative) among you, as is proper among saints Comment - This verb denotes the speaking of something by mentioning the name of it. However, the text does not mean that one should not even use a term such as πλεονεξία ‘covetousness’, but that there should never be a reason to have to speak of greed, since no one in the congregation should be guilty of such a thing [LN]. (Graham, Glenn:; An Exegetical Summary of Ephesian) 2 Timothy 2:19 Nevertheless, the firm foundation of God stands, having this seal, "The Lord knows those who are His," and, "Everyone who names the name of the Lord is to abstain from wickedness."
