On the Trinity; doctrinal and moral treatises

10. And since we are showing how we can say the Father alone, because there is no Father in the Godhead except Himself, we must consider also the opinion which holds that the only true God is not the Father alone, but the Father and the Son and the Holy Spirit. For if any one should ask whether the Father alone is God, how can it be replied that He is not, unless perhaps we were to say that the Father indeed is God, but that He is not God alone, but that the Father, Son, and Holy Spirit are God alone? But then what shall we do with that testimony of the Lord? For He was speaking to the Father, and had named the Father as Him to whom He was speaking, when He says, "And this is life eternal, that they may know Thee the one true God."¹ And this the Arians indeed usually take, as if the Son were not true God. Passing them by, however, we must see whether, when it is said to the Father, "That they may know Thee the one true God," we are forced to understand it as if He wished to intimate that the Father alone is the true God; lest we should not understand any to be God, except the three together, the Father, Son, and Holy Spirit. Are we therefore, from the testimony of the Lord, both to call the Father the one true God, and the Son the one true God, and the Holy Spirit the one true God, and the Father, the Son, and the Holy Spirit together, that is, the Trinity itself together, not three true Gods but one true God? Or because He added, "And Jesus Christ whom Thou hast sent," are we to supply "the one true God;" so that the order of the words is this, "That they may know Thee, and Jesus Christ whom Thou hast sent, the one true God?" Why then did He omit to mention the Holy Spirit? Is it because it follows, that whenever we name One who cleaves to One by a harmony so great that through this harmony both are one, this harmony itself must be understood, although it is not mentioned? For in that place, too, the apostle seems as it were to pass over the Holy Spirit; and yet there, too, He is understood, where he says, "All are yours, and ye are Christ's, and Christ is God's."² And again, "The head of the woman is the man, the head of the man is Christ, and the head of Christ is God."³ But again, if God is only all three together, how can God be the head of Christ, that is, the Trinity the head of Christ, since Christ is in the Trinity in order that it may be the Trinity? Is that which is the Father with the Son, the head of that which is the Son alone? For the Father with the Son is God, but the Son alone is Christ: especially since it is the Word already made flesh that speaks; and according to this His humiliation also, the Father is greater than He, as He says, "for my Father is greater than I;"⁴ so that the very being of God, which is one to Him with the Father, is itself the head of the man who is mediator, which He is alone.⁵ For if we rightly call the mind the chief thing of man, that is, as it were the head of the human substance, although the man himself together with the mind is man; why is not the Word with the Father, which together is God, much more suitably and much more the head of Christ, although Christ as man cannot be understood except with the Word which was made flesh? But this, as we have already said, we shall consider somewhat more carefully hereafter. At present the equality and one and the same substance of the Trinity has been demonstrated as briefly as possible, that in whatever way that other question be determined, the more rigorous discussion of which we have deferred, nothing may hinder us from confessing the absolute equality of the Father, Son, and Holy Spirit.

11. A certain writer, when he would briefly intimate the special attributes of each of the persons in the Trinity, tells us that "Eternity is in the Father, form in the Image, use in the Gift." And since he was a man of no mean authority in handling the Scriptures, and in the assertion of the faith, for it is Hilary who put this in his book (On the Trinity, ii.); I have searched into the hidden meaning of these words as far as I can, that is, of the Father, and the Image, and the Gift, of eternity, and of form, and of use. And I do not think that he intended more by the word eternity, than that the Father has not a father from whom He is; but the Son is from the Father, so as to be, and so as to be co-eternal with Him. For if an image perfectly fills the measure of that of which it is the image, then the image is made equal to that of which it is the image, not the latter to its own image. And in respect to this image he has named form, I believe on account of the quality of beauty, where there is at once such great fitness, and prime equality, and prime likeness, differing in nothing, and unequal in no respect, and in no part unlike, but answering exactly to Him whose image it is: where there is prime and absolute life, to whom it is not one thing to live, and another to be, but the same thing to be and to live; and prime and absolute intellect, to whom it is not one thing to live, another to understand, but to understand is to live, and is to be, and all things are one: as though a perfect Word (John i. 1), to which nothing is wanting, and a certain skill of the omnipotent and wise God, full of all living, unchangeable sciences, and all one in it, as itself is one from one, with whom it is one. Therein God knew all things which He made by it; and therefore, while times pass away and succeed, nothing passes away or succeeds to the knowledge of God. For things which are created are not therefore known by God, because they have been made; and not rather have been therefore made, even although changeable, because they are known unchangeably by Him. Therefore that unspeakable conjunction of the Father and His image is not without fruition, without love, without joy. Therefore that love, delight, felicity, or blessedness, if indeed it can be worthily expressed by any human word, is called by him, in short, Use; and is the Holy Spirit in the Trinity, not begotten, but the sweetness of the begetter and of the begotten, filling all creatures according to their capacity with abundant bountifulness and copiousness, that they may keep their proper order and rest satisfied in their proper place.

12. Therefore all these things which are made by divine skill, show in themselves a certain unity, and form, and order; for each of them is both some one thing, as are the several natures of bodies and dispositions of souls; and is fashioned in some form, as are the figures or qualities of bodies, and the various learning or skill of souls; and seeks or preserves a certain order, as are the several weights or combinations of bodies and the loves or delights of souls. When therefore we regard the Creator, who is understood by the things that are made⁶ we must needs understand the Trinity of whom there appear traces in the creature, as is fitting. For in that Trinity is the supreme source of all things, and the most perfect beauty, and the most blessed delight. Those three, therefore, both seem to be mutually determined to each other, and are in themselves infinite. But here in corporeal things, one thing alone is not as much as three together, and two are something more than one; but in that highest Trinity one is as much as the three together, nor are two anything more than one. And They are infinite in themselves. So both each are in each, and all in each, and each in all, and all in all, and all are one. Let him who sees this, whether in part, or "through a glass and in an enigma,"⁷ rejoice in knowing God; and let him honor Him as God, and give thanks; but let him who does not see it, strive to see it through piety, not to cavil at it through blindness. Since God is one, but yet is a Trinity. Neither are we to take the words, "of whom, and through whom, and to whom are all things," as used indiscriminately [i.e., to denote a unity without distinctions]; nor yet to denote many gods, for "to Him, be glory for ever and ever. Amen."⁸

1. Let us now inquire more carefully, so far as God grants, into that which a little before we deferred; whether each person also in the Trinity can also by Himself and not with the other two be called God, or great, or wise, or true, or omnipotent, or just, or anything else that can be said of God, not relatively, but absolutely; or whether these things cannot be said except when the Trinity is understood. For the question is raised,—because it is written, "Christ the power of God, and the wisdom of God,"⁹ —whether He is so the Father of His own wisdom and His own power, as that He is wise with that wisdom which He begat, and powerful with that power which He begat; and whether, since He is always powerful and wise, He always begat power and wisdom. For if it be so, then, as we have said, why is He not also the Father of His own greatness by which He is great, and of His own goodness by which He is good, and of His own justice by which He is just, and whatever else there is? Or if all these things are understood, although under more names than one, to be in the same wisdom and power, so that that is greatness which is power, that is goodness which is wisdom, and that again is wisdom which is power, as we have already argued; then let us remember, that when I mention any one of these, I am to be taken as if I mentioned all. It is asked, then, whether the Father also by Himself is wise, and is Himself His own wisdom itself; or whether He is wise in the same way as He speaks. For He speaks by the Word which He begat, not by the word which is uttered, and sounds, and passes away, but by the Word which was with God, and the Word was God, and all things were made by Him:¹⁰ by the Word which is equal to Himself, by whom He always and unchangeably utters Himself. For He is not Himself the Word, as He is not the Son nor the image. But in speaking (putting aside those words of God in time which are produced in the creature, for they sound and pass away,—in speaking then) by that co-eternal Word, He is not understood singly, but with that Word itself, without whom certainly He does not speak. Is He then in such way wise as He is one who speaks, so as to be in such way wisdom, as He is the Word, and so that to be the Word is to be wisdom, that is, also to be power, so that power and wisdom and the Word may be the same, and be so called relatively as the Son and the image: and that the Father is not singly powerful or wise, but together with the power and wisdom itself which He begat (genuit); just as He is not singly one who speaks, but by that Word and together with that Word which He begat; and in like way great by that and together with that greatness, which He begat? And if He is not great by one thing, and God by another, but great by that whereby He is God, because it is not one thing to Him to be great and another to be God; it follows that neither is He God singly, but by that and together with that deity (deitas) which He begat; so that the Son is the deity of the Father, as He is the wisdom and power of the Father, and as He is the Word and image of the Father. And because it is not one thing to Him to be, another to be God, the Son is also the essence of the Father, as He is His Word and image. And hence also—except that He is the Father [the Unbegotten]—the Father is not anything unless because He has the Son; so that not only that which is meant by Father (which it is manifest He is not called relatively to Himself but to the Son, and therefore is the Father because He has the Son), but that which He is in respect to His own substance is so called, because He begat His own essence. For as He is great, only with that greatness which He begat, so also He is, only with that essence which He begat; because it is not one thing to Him to be, and another to be great. Is He therefore the Father of His own essence, in the same way as He is the Father of His own greatness, as He is the Father of His own power and wisdom? since His greatness is the same as His power, and His essence the same as His greatness.

2. This discussion has arisen from that which is written, that "Christ is the power of God, and the wisdom of God." Wherefore our discourse is compressed into these narrow limits, while we desire to speak things unspeakable; that either we must say that Christ is not the power of God and the wisdom of God, and so shamelessly and impiously resist the apostle; or we must acknowledge that Christ is indeed the power of God and the wisdom of God, but that His Father is not the Father of His own power and wisdom, which is not less impious; for so neither will He be the Father of Christ, because Christ is the power of God and the wisdom of God; or that the Father is not powerful with His own power, or wise with His own wisdom: and who shall dare to say this? Or yet, again, that we must understand, that in the Father it is one thing to be, another thing to be wise, so that He is not by that by which He is wise: a thing usually understood of the soul, which is at some times unwise, at others wise; as being by nature changeable, and not absolutely and perfectly simple. Or, again, that the Father is not anything in respect to His own substance; and that not only that He is the Father, but that He is, is said relatively to the Son. How then can the Son be of the same essence as the Father, seeing that the Father, in respect to Himself, is neither His own essence, nor is at all in respect to Himself, but even His essence is in relation to the Son? But, on the contrary, much more is He of one and the same essence, since the Father and Son are one and the same essence; seeing that the Father has His being itself not in respect to Himself, but to the Son, which essence He begat, and by which essence He is whatever He is. Therefore neither [person] is in respect to Himself alone; and both exist relatively the one to the other. Or is the Father alone not called Father of himself, but whatever He is called, is called relatively to the Son, but the Son is predicated of in reference to Himself? And if it be so, what is predicated of Him in reference to Himself? Is it His essence itself? But the Son is the essence of the Father, as He is the power and wisdom of the Father, as He is the Word of the Father, and the image of the Father. Or if the Son is called essence in reference to Himself, but the Father is not essence, but the begetter of the essence, and is not in respect to Himself, but is by that very essence which He begat; as He is great by that greatness which He begat: therefore the Son is also called greatness in respect to Himself; therefore He is also called, in like manner, power, and wisdom, and word, and image. But what can be more absurd than that He should be called image in respect to Himself? Or if image and word are not the very same with power and wisdom, but the former are spoken relatively, and the latter in respect to self, not to another; then we get to this, that the Father is not wise with that wisdom which He begat, because He Himself cannot be spoken relatively to it, and it cannot be spoken relatively to Him. For all things which are said relatively are said reciprocally; therefore it remains that even in essence the Son is spoken of relatively to the Father. But from this is educed a most unexpected sense: that essence itself is not essence, or at least that, when it is called essence, not essence but something relative is intimated. As when we speak of a master, essence is not intimated, but a relative which has reference to a slave; but when we speak of a man, or any such thing which is said in respect to self not to something else, then essence is intimated. Therefore when a man is called a master, man himself is essence, but he is called master relatively; for he is called man in respect to himself, but master in respect to his slave. But in regard to the point from which we started, if essence itself is spoken relatively, essence itself is not essence. Add further, that all essence which is spoken of relatively, is also something, although the relation be taken away; as e.g. in the case of a man who is a master, and a man who is a slave, and a horse that is a beast of burden, and money that is a pledge, the man, and the horse, and the money are spoken in respect to themselves, and are substances or essences; but master, and slave, and beast of burden, and pledge, are spoken relatively to something. But if there were not a man, that is, some substance, there would be none who could be called relatively a master; and if there were no horse having a certain essence, there would be nothing that could be called relatively a beast of burden; so if money were not some kind of substance, it could not be called relatively a pledge. Wherefore, if the Father also is not something in respect to Himself then there is no one at all that can be spoken of relatively to something. For it is not as it is with color. The color of a thing is referred to the thing colored, and color is not spoken at all in reference to substance, but is always of something that is colored; but that thing of which it is the color, even if it is referred to color in respect to its being colored, is yet, in respect to its being a body, spoken of in respect to substance. But in no way may we think, in like manner, that the Father cannot be called anything in respect to His own substance, but that whatever He is called, He is called in relation to the Son; while the same Son is spoken of both in respect to His own substance and in relation to the Father, when He is called great greatness, and powerful power, plainly in respect to Himself, and the greatness and power of the great and powerful Father, by which the Father is great and powerful. It is not so; but both are substance, and both are one substance. And as it is absurd to say that whiteness is not white, so is it absurd to say that wisdom is not wise; and as whiteness is called white in respect to itself, so also wisdom is called wise in respect to itself. But the whiteness of a body is not an essence, since the body itself is the essence, and that is a quality of it; and hence also a body is said from that quality to be white, to which body to be is not the same thing as to be white. For the form in it is one thing, and the color another; and both are not in themselves, but in a certain bulk, which bulk is neither form nor color, but is formed and colored. True wisdom is both wise, and wise in itself. And since in the case of every soul that becomes wise by partaking of wisdom, if it again becomes foolish, yet wisdom in itself remains; nor when that soul was changed into folly is the wisdom likewise so changed; therefore wisdom is not in him who becomes wise by it, in the same manner as whiteness is in the body which is by it made white. For when the body has been changed into another color, that whiteness will not remain, but will altogether cease to be. But if the Father who begat wisdom is also made wise by it, and to be is not to Him the same as to be wise, then the Son is His quality, not His offspring; and there will no longer be absolute simplicity in the Godhead. But far be it from being so, since in truth in the Godhead is absolutely simple essence, and therefore to be is there the same as to be wise. But if to be is there the same as to be wise, then the Father is not wise by that wisdom which He begat; otherwise He did not beget it, but it begat Him. For what else do we say when we say, that to Him to be is the same as to be wise, unless that He is by that whereby He is wise? Wherefore, that which is the cause to Him of being wise, is itself also the cause to Him that He is; and accordingly, if the wisdom which He begat is the cause to Him of being wise, it is also the cause to Him that He is; and this cannot be the case, except either by begetting or by creating Him. But no one ever said in any sense that wisdom is either the begetter or the creator of the Father; for what could be more senseless? Therefore both the Father Himself is wisdom, and the Son is in such way called the wisdom of the Father, as He is called the light of the Father; that is, that in the same manner as light from light, and yet both one light, so we are to understand wisdom of wisdom, and yet both one wisdom; and therefore also one essence, since, in God, to be, is the same as to be wise. For what to be wise is to wisdom, and to be able is to power, and to be eternal is to eternity, and to be just to justice, and to be great to greatness, that being itself is to essence. And since in the Divine simplicity, to be wise is nothing else than to be, therefore wisdom there is the same as essence.

3. Therefore the Father and the Son together are one essence, and one greatness, and one truth, and one wisdom. But the Father and Son both together are not one Word, because both together are not one Son. For as the Son is referred to the Father, and is not so called in respect to Himself, so also the Word is referred to him whose Word it is, when it is called the Word. Since He is the Son in that He is the Word, and He is the Word in that He is the Son. Inasmuch, therefore, as the Father and the Son together are certainly not one Son, it follows that the Father and the Son together are not the one Word of both. And therefore He is not the Word in that He is wisdom; since He is not called the Word in respect to Himself, but only relatively to Him whose Word He is, as He is called the Son in relation to the Father; but He is wisdom by that whereby He is essence. And therefore, because one essence, one wisdom. But since the Word is also wisdom, yet is not thereby the Word because He is wisdom for He is understood to be the Word relatively, but wisdom essentially: let us understand, that when He is called the Word, it is meant, wisdom that is born, so as to be both the Son and the Image; and that when these two words are used, namely wisdom (is) born, in one of the two, namely born,¹¹ both Word, and Image, and Son, are understood, and in all these names essence is not expressed, since they are spoken relatively; but in the other word, namely wisdom, since it is spoken also in respect to substance, for wisdom is wise in itself, essence also is expressed, and that being of His which is to be wise. Whence the Father and Son together are one wisdom, because one essence, and singly wisdom of wisdom, as essence of essence. And hence they are not therefore not one essence, because the Father is not the Son, and the Son is not the Father, or because the Father is un-begotten, but the Son is begotten: since by these names only their relative attributes are expressed. But both together are one wisdom and one essence; in which to be, is the same as to be wise. And both together are not the Word or the Son, since to be is not the same as to be the Word or the Son, as we have already sufficiently shown that these terms are spoken relatively.

4. Why, then, is scarcely anything ever said in the Scriptures of wisdom, unless to show that it is begotten or created of God?—begotten in the case of that Wisdom by which all things are made; but created or made, as in men, when they are converted to that Wisdom which is not created and made but begotten, and are so enlightened; for in these men themselves there comes to be something which may be called their wisdom: even as the Scriptures foretell or narrate, that "the Word was made flesh, and dwelt among us;"¹² for in this way Christ was made wisdom, because He was made man. Is it on this account that wisdom does not speak in these books, nor is anything spoken of it, except to declare that it is born of God, or made by Him (although the Father is Himself wisdom), namely, because wisdom ought to be commended and imitated by us, by the imitation of which we are fashioned [rightly]? For the Father speaks it, that it may be His Word: yet not as a word producing a sound proceeds from the mouth, or is thought before it is pronounced. For this word is completed in certain spaces of time, but that is eternal, and speaks to us by enlightening us, what ought to be spoken to men, both of itself and of the Father. And therefore He says, "No man knoweth the Son, but the Father; neither knoweth any man the Father, save the Son, and he to whomsoever the Son will reveal Him:"¹³ since the Father reveals by the Son, that is, by His Word. For if that word which we utter, and which is temporal and transitory, declares both itself, and that of which we speak, how much more the Word of God, by which all things are made? For this Word so declares the Father as He is the Father; because both itself so is, and is that which is the Father, in so far as it is wisdom and essence. For in so far as it is the Word, it is not what the Father is; because the Word is not the Father, and Word is spoken relatively, as is also Son, which assuredly is not the Father. And therefore Christ is the power and wisdom of God, because He Himself, being also power and wisdom, is from the Father, who is power and wisdom; as He is light of the Father, who is light, and the fountain of life with God the Father, who is Himself assuredly the fountain of life. For "with Thee," He says, "is the fountain of life, and in Thy light shall we see light."¹⁴ Because, "as the Father hath life in Himself, so hath He given to the Son to have life in Himself:"¹⁵ and, "He was the true Light, which lighteth every man that cometh into the world:" and this light, "the Word," was "with God;" but "the Word also was God;"¹⁶ and "God is light, and in Him is no darkness at all:"¹⁷ but a light that is not corporeal, but spiritual; yet not in such way spiritual, that it was wrought by illumination, as it was said to the apostles, "Ye are the light of the world,"¹⁸ but "the light which lighteth every man," that very supreme wisdom itself who is God, of whom we now treat. The Son therefore is Wisdom of wisdom, namely the Father, as He is Light of light, and God of God; so that both the Father singly is light, and the Son singly is light; and the Father singly is God, and the Son singly is God: therefore the Father also singly is wisdom, and the Son singly is wisdom. And as both together are one light and one God, so both are one wisdom. But the Son is "by God made unto us wisdom, and righteousness, and sanctification;"¹⁹ because we turn ourselves to Him in time, that is, from some particular time, that we may remain with Him for ever. And He Himself from a certain time was "the Word made flesh, and dwelt among us."

5. On this account, then, when anything concerning wisdom is declared or narrated in the Scriptures, whether as itself speaking, or where anything is spoken of it, the Son chiefly is intimated to us. And by the example of Him who is the image, let us also not depart from God, since we also are the Image of God: not indeed that which is equal to Him, since we are made so by the Father through the Son, and not born of the Father, as that is. And we are so, because we are enlightened with light; but that is so, because it is the light that enlightens; and which, therefore, being without pattern, is to us a pattern. For He does not imitate any one going before Him, in respect to the Father, from whom He is never separable at all, since He is the very same substance with Him from whom He is. But we by striving imitate Him who abides, and follow Him who stands still, and walking in Him, reach out towards Him; because He is made for us a way in time by His humiliation, which is to us an eternal abiding-place by His divinity. For since to pure intellectual spirits, who have not fallen through pride, He gives an example in the form of God and as equal with God and as God; so, in order that He might also give Himself as an example of returning to fallen man who on account of the uncleanness of sins and the punishment of mortality cannot see God, "He emptied Himself;" not by changing His own divinity, but by assuming our changeableness: and "taking upon Him the form of a servant"²⁰ He came to us into this world,"²¹ who "was in this world," because "the world was made by Him;"²² that He might be an example upwards to those who see God, an example downwards to those who admire man, an example to the sound to persevere, an example to the sick to be made whole, an example to those who are to die that they may not fear, an example to the dead that they may rise again, "that in all things He might have the pre-eminence."²³ So that, because man ought not to follow any except God to blessedness, and yet cannot perceive God; by following God made man, he might follow at once Him whom he could perceive, and whom he ought to follow. Let us then love Him and cleave to Him, by charity spread abroad in our hearts, through the Holy Spirit which is given unto us.²⁴ It is not therefore to be wondered at, if, on account of the example which the Image, which is equal to the Father, gives to us, in order that we may be refashioned after the image of God, Scripture, when it speaks of wisdom, speaks of the Son, whom we follow by living wisely; although the Father also is wisdom, as He is both light and God.

6. The Holy Spirit also, whether we are to call Him that absolute love which joins together Father and Son, and joins us also from beneath, that so that is not unfitly said which is written, "God is love;"²⁵ how is He not also Himself wisdom, since He is light, because "God is light"? or whether after any other way the essence of the Holy Spirit is to be singly and properly named; then, too, since He is God, He is certainly light; and since He is light, He is certainly wisdom. But that the Holy Spirit is God, Scripture proclaims by the apostle, who says, "Know ye not that ye are the temple of God?" and immediately subjoins, "And the Spirit of God dwelleth in you;"²⁶ for God dwelleth in His own temple. For the Spirit of God does not dwell in the temple of God as a servant, since he says more plainly in another place, "Know ye not that your body is the temple of the Holy Ghost which is in you, and which ye have of God, and ye are not your own? For ye are bought with a great price: therefore glorify God in your body."²⁷ But what is wisdom, except spiritual and unchangeable light? For yonder sun also is light, but it is corporeal; and the spiritual creature also is light, but it is not unchangeable. Therefore the Father is light, the Son is light, and the Holy Spirit is light; but together not three lights, but one light. And so the Father is wisdom, the Son is wisdom, and the Holy Spirit is wisdom, and together not three wisdoms, but one wisdom: and because in the Trinity to be is the same as to be wise, the Father, Son, and Holy Spirit, are one essence. Neither in the Trinity is it one thing to be and another to be God; therefore the Father, Son, and Holy Spirit, are one God.
