1. I know that some will attempt to say that, even according to the declarations of our own Scriptures, God is a body, because in the writings of Moses they find it said, that |our God is a consuming fire;| and in the Gospel according to John, that |God is a Spirit, and they who worship Him must worship Him in spirit and in truth.| Fire and spirit, according to them, are to be regarded as nothing else than a body. Now, I should like to ask these persons what they have to say respecting that passage where it is declared that God is light; as John writes in his Epistle, |God is light, and in Him there is no darkness at all.| Truly He is that light which illuminates the whole understanding of those who are capable of receiving truth, as is said in the thirty-sixth Psalm, |In Thy light we shall see light.| For what other light of God can be named, |in which any one sees light,| save an influence of God, by which a man, being enlightened, either thoroughly sees the truth of all things, or comes to know God Himself, who is called the truth? Such is the meaning of the expression, |In Thy light we shall see light;| i.e., in Thy word and wisdom which is Thy Son, in Himself we shall see Thee the Father. Because He is called light, shall He be supposed to have any resemblance to the light of the sun? Or how should there be the slightest ground for imagining, that from that corporeal light any one could derive the cause of knowledge, and come to the understanding of the truth?
2. If, then, they acquiesce in our assertion, which reason itself has demonstrated, regarding the nature of light, and acknowledge that God cannot be understood to be a body in the sense that light is, similar reasoning will hold true of the expression |a consuming fire.| For what will God consume in respect of His being fire? Shall He be thought to consume material substance, as wood, or hay, or stubble? And what in this view can be called worthy of the glory of God, if He be a fire, consuming materials of that kind? But let us reflect that God does indeed consume and utterly destroy; that He consumes evil thoughts, wicked actions, and sinful desires, when they find their way into the minds of believers; and that, inhabiting along with His Son those souls which are rendered capable of receiving His word and wisdom, according to His own declaration, |I and the Father shall come, and We shall make our abode with him?| He makes them, after all their vices and passions have been consumed, a holy temple, worthy of Himself. Those, moreover, who, on account of the expression |God is a Spirit,| think that He is a body, are to be answered, I think, in the following manner. It is the custom of sacred Scripture, when it wishes to designate anything opposed to this gross and solid body, to call it spirit, as in the expression, |The letter killeth, but the spirit giveth life,| where there can be no doubt that by |letter| are meant bodily things, and by |spirit| intellectual things, which we also term |spiritual.| The apostle, moreover, says, |Even unto this day, when Moses is read, the veil is upon their heart: nevertheless, when it shall turn to the Lord, the veil shall be taken away: and where the Spirit of the Lord is, there is liberty.| For so long as any one is not converted to a spiritual understanding, a veil is placed over his heart, with which veil, i.e., a gross understanding, Scripture itself is said or thought to be covered: and this is the meaning of the statement that a veil was placed over the countenance of Moses when he spoke to the people, i.e., when the law was publicly read aloud. But if we turn to the Lord, where also is the word of God, and where the Holy Spirit reveals spiritual knowledge, then the veil is taken away, and with unveiled face we shall behold the glory of the Lord in the holy Scriptures.
3. And since many saints participate in the Holy Spirit, He cannot therefore be understood to be a body, which being divided into corporeal parts, is partaken of by each one of the saints; but He is manifestly a sanctifying power, in which all are said to have a share who have deserved to be sanctified by His grace. And in order that what we say may be more easily understood, let us take an illustration from things very dissimilar. There are many persons who take a part in the science or art of medicine: are we therefore to suppose that those who do so take to themselves the particles of some body called medicine, which is placed before them, and in this way participate in the same? Or must we not rather understand that all who with quick and trained minds come to understand the art and discipline itself, may be said to be partakers of the art of healing? But these are not to be deemed altogether parallel instances in a comparison of medicine to the Holy Spirit, as they have been adduced only to establish that that is not necessarily to be considered a body, a share in which is possessed by many individuals. For the Holy Spirit differs widely from the method or science of medicine, in respect that the Holy Spirit is an intellectual existence and subsists and exists in a peculiar manner, whereas medicine is not at all of that nature.
4. But we must pass on to the language of the Gospel itself, in which it is declared that |God is a Spirit,| and where we have to show how that is to be understood agreeably to what we have stated. For let us inquire on what occasion these words were spoken by the Saviour, before whom He uttered them, and what was the subject of investigation. We find, without any doubt, that He spoke these words to the Samaritan woman, saying to her, who thought, agreeably to the Samaritan view, that God ought to be worshipped on Mount Gerizim, that |God is a Spirit.| For the Samaritan woman, believing Him to be a Jew, was inquiring of Him whether God ought to be worshipped in Jerusalem or on this mountain; and her words were, |All our fathers worshipped on this mountain, and ye say that in Jerusalem is the place where we ought to worship.| To this opinion of the Samaritan woman, therefore, who imagined that God was less rightly or duly worshipped, according to the privileges of the different localities, either by the Jews in Jerusalem or by the Samaritans on Mount Gerizim, the Saviour answered that he who would follow the Lord must lay aside all preference for particular places, and thus expressed Himself: |The hour is coming when neither in Jerusalem nor on this mountain shall the true worshippers worship the Father. God is a Spirit, and they who worship Him must worship Him in spirit and in truth.| And observe how logically He has joined together the spirit and the truth: He called God a Spirit, that He might distinguish Him from bodies; and He named Him the truth, to distinguish Him from a shadow or an image. For they who worshipped in Jerusalem worshipped God neither in truth nor in spirit, being in subjection to the shadow or image of heavenly things; and such also was the case with those who worshipped on Mount Gerizim.
5. Having refuted, then, as well as we could, every notion which might suggest that we were to think of God as in any degree corporeal, we go on to say that, according to strict truth, God is incomprehensible, and incapable of being measured. For whatever be the knowledge which we are able to obtain of God, either by perception or reflection, we must of necessity believe that He is by many degrees far better than what we perceive Him to be. For, as if we were to see any one unable to bear a spark of light, or the flame of a very small lamp, and were desirous to acquaint such a one, whose vision could not admit a greater degree of light than what we have stated, with the brightness and splendour of the sun, would it not be necessary to tell him that the splendour of the sun was unspeakably and incalculably better and more glorious than all this light which he saw? So our understanding, when shut in by the fetters of flesh and blood, and rendered, on account of its participation in such material substances, duller and more obtuse, although, in comparison with our bodily nature, it is esteemed to be far superior, yet, in its efforts to examine and behold incorporeal things, scarcely holds the place of a spark or lamp. But among all intelligent, that is, incorporeal beings, what is so superior to all others -- so unspeakably and incalculably superior -- as God, whose nature cannot be grasped or seen by the power of any human understanding, even the purest and brightest?
6. But it will not appear absurd if we employ another similitude to make the matter clearer. Our eyes frequently cannot look upon the nature of the light itself -- that is, upon the substance of the sun; but when we behold his splendour or his rays pouring in, perhaps, through windows or some small openings to admit the light, we can reflect how great is the supply and source of the light of the body. So, in like manner. the works of Divine Providence and the plan of this whole world are a sort of rays, as it were, of the nature of God, in comparison with His real substance and being. As, therefore, our understanding is unable of itself to behold God Himself as He is, it knows the Father of the world from the beauty of His works and the comeliness of His creatures. God, therefore, is not to be thought of as being either a body or as existing in a body, but as an uncompounded intellectual nature, admitting within Himself no addition of any kind; so that He cannot be believed to have within him a greater and a less, but is such that He is in all parts Monas, and, so to speak, Enas, and is the mind and source from which all intellectual nature or mind takes its beginning. But mind, for its movements or operations, needs no physical space, nor sensible magnitude, nor bodily shape, nor colour, nor any other of those adjuncts which are the properties of body or matter. Wherefore that simple and wholly intellectual nature can admit of no delay or hesitation in its movements or operations, lest the simplicity of the divine nature should appear to be circumscribed or in some degree hampered by such adjuncts, and lest that which is the beginning of all things should be found composite and differing, and that which ought to be free from all bodily intermixture, in virtue of being the one sole species of Deity, so to speak, should prove, instead of being one, to consist of many things. That mind, moreover, does not require space in order to carry on its movements agreeably to its nature, is certain from observation of our own mind. For if the mind abide within its own limits, and sustain no injury from any cause, it will never, from diversity of situation, be retarded in the discharge of its functions; nor, on the other hand, does it gain any addition or increase of mobility from the nature of particular places. And here, if any one were to object, for example, that among those who are at sea, and tossed by its waves the mind is considerably less vigorous than it is wont to be on land, we are to believe that it is in this state, not from diversity of situation, but from the commotion or disturbance of the body to which the mind is joined or attached. For it seems to be contrary to nature, as it were, for a human body to live at sea; and for that reason it appears, by a sort of inequality of its own, to enter upon its mental operations in a slovenly and irregular manner, and to perform the acts of the intellect with a duller sense, in as great degree as those who on land are prostrated with fever; with respect to whom it is certain, that if the mind do not discharge its functions as well as before, in consequence of the attack of disease, the blame is to be laid not upon the place, but upon the bodily malady, by which the body, being disturbed and disordered, renders to the mind its customary services under by no means the well-known and natural conditions: for we human beings are animals composed of a union of body and soul, and in this way (only) was it possible for us to live upon the earth. But God, who is the beginning of all things, is not to be regarded as a composite being, lest perchance there should be found to exist elements prior to the beginning itself, out of which everything is composed, whatever that be which is called composite. Neither does the mind require bodily magnitude in order to perform any act or movement; as when the eye by gazing upon bodies of larger size is dilated, but is compressed and contracted in order to see smaller objects. The mind, indeed, requires magnitude of an intellectual kind, because it grows, not after the fashion of a body, but after that of intelligence. For the mind is not enlarged, together with the body, by means of corporal additions, up to the twentieth or thirtieth year of life; but the intellect is sharpened by exercises of learning, and the powers implanted within it for intelligent purposes are called forth; and it is rendered capable of greater intellectual efforts, not being increased by bodily additions, but carefully polished by learned exercises. But these it cannot receive immediately from boyhood, or from birth, because the framework of limbs which the mind employs as organs for exercising itself is weak and feeble; and it is unable to bear the weight of its own operations, or to exhibit a capacity for receiving training.
7. If there are any now who think that the mind itself and the soul is a body, I wish they would tell me by way of answer how it receives reasons and assertions on subjects of such importance -- of such difficulty and such subtlety? Whence does it derive the power of memory? and whence comes the contemplation of invisible things? How does the body possess the faculty of understanding incorporeal existences? How does a bodily nature investigate the processes of the various arts, and contemplate the reasons of things? How, also, is it able to perceive and understand divine truths, which are manifestly incorporeal? Unless, indeed, some should happen to be of opinion, that as the very bodily shape and form of the ears or eyes contributes something to hearing and to sight, and as the individual members, formed by God, have some adaptation, even from the very quality of their form, to the end for which they were naturally appointed; so also he may think that the shape of the soul or mind is to be understood as if created purposely and designedly for perceiving and understanding individual things, and for being set in motion by vital movements. I do not perceive, however, who shall be able to describe or state what is the colour of the mind, in respect of its being mind, and acting as an intelligent existence. Moreover, in confirmation and explanation of what we have already advanced regarding the mind or soul -- to the effect that it is better than the whole bodily nature -- the following remarks may be added. There underlies every bodily sense a certain peculiar sensible substance, on which the bodily sense exerts itself. For example, colours, form, size, underlie vision; voices and sound, the sense of hearing; odours, good or bad, that of smell; savours, that of taste; heat or cold, hardness or softness, roughness or smoothness, that of touch. Now, of those senses enumerated above, it is manifest to all that the sense of mind is much the best. How, then, should it not appear absurd, that under those senses which are inferior, substances should have been placed on which to exert their powers, but that under this power, which is far better than any other, i.e., the sense of mind, nothing at all of the nature of a substance should be placed, but that a power of an intellectual nature should be an accident, or consequent upon bodies? Those who assert this, doubtless do so to the disparagement of that better substance which is within them; nay, by so doing, they even do wrong to God Himself, when they imagine He may be understood by means of a bodily nature, so that according to their view He is a body, and that which may be understood or perceived by means of a body; and they are unwilling to have it understood that the mind bears a certain relationship to God, of whom the mind itself is an intellectual image, and that by means of this it may come to some knowledge of the nature of divinity, especially if it be purified and separated from bodily matter.
8. But perhaps these declarations may seem to have less weight with those who wish to be instructed in divine things out of the holy Scriptures, and who seek to have it proved to them from that source how the nature of God surpasses the nature of bodies. See, therefore, if the apostle does not say the same thing, when, speaking of Christ, he declares, that |He is the image of the invisible God, the first-born of every creature.| Not, as some suppose, that the nature of God is visible to some and invisible to others: for the apostle does not say |the image of God invisible| to men or |invisible| to sinners, but with unvarying constancy pronounces on the nature of God in these words: |the image of the invisible God.| Moreover, John, in his Gospel, when asserting that |no one hath seen God at any time,| manifestly declares to all who are capable of understanding, that there is no nature to which God is visible: not as if, He were a being who was visible by nature, and merely escaped or baffled the view of a frailer creature, but because by the nature of His being it is impossible for Him to be seen. And if you should ask of me what is my opinion regarding the Only-begotten Himself, whether the nature of God, which is naturally invisible, be not visible even to Him, let not such a question appear to you at once to be either absurd or impious, because we shall give you a logical reason. It is one thing to see, and another to know: to see and to be seen is a property of bodies; to know and to be known, an attribute of intellectual being. Whatever, therefore, is a property of bodies, cannot be predicated either of the Father or of the Son; but what belongs to the nature of deity is common to the Father and the Son. Finally, even He Himself, in the Gospel, did not say that no one has seen the Father, save the Son, nor any one the Son, save the Father; but His words are: |No one knoweth the Son, save the Father; nor any one the Father, save the Son.| By which it is clearly shown, that whatever among bodily natures is called seeing and being seen, is termed, between the Father and the Son, a knowing and being known, by means of the power of knowledge, not by the frailness of the sense of sight. Because, then, neither seeing nor being seen can be properly applied to an incorporeal and invisible nature, neither is the Father, in the Gospel, said to be seen by the Son, nor the Son by the Father, but the one is said to be known by the other.
9. Here, if any one lay before us the passage where it is said, |Blessed are the pure in heart, for they shall see God,| from that very passage, in my opinion, will our position derive additional strength; for what else is seeing God in heart, but, according to our exposition as above, understanding and knowing Him with the mind? For the names of the organs of sense are frequently applied to the soul, so that it may be said to see with the eyes of the heart, i.e., to perform an intellectual act by means of the power of intelligence. So also it is said to hear with the ears when it perceives the deeper meaning of a statement. So also we say that it makes use of teeth, when it chews and eats the bread of life which cometh down from heaven. In like manner, also, it is said to employ the services of other members, which are transferred from their bodily appellations, and applied to the powers of the soul, according to the words of Solomon, |You will find a divine sense.| For he knew that there were within us two kinds of senses: the one mortal, corruptible, human; the other immortal and intellectual, which he now termed divine. By this divine sense, therefore, not of the eyes, but of a pure heart, which is the mind, God may be seen by those who are worthy. For you will certainly find in all the Scriptures, both old and new, the term |heart| repeatedly used instead of |mind,| i.e., intellectual power. In this manner, therefore, although far below the dignity of the subject, have we spoken of the nature of God, as those who understand it under the limitation of the human understanding. In the next place, let us see what is meant by the name of Christ.
