Caput I: Book 1

Caput I: This Work is Written Against Those Who Sophistically Assail the Faith of the Trinity, Through Misuse of Reason. They Who Dispute Concerning God Err from a Threefold Cause. Holy Scripture, Removing What is False, Leads Us on by Degrees to Things Divine. What True Immortality is. We are Nourished by Faith, that We May Be Enabled to Apprehend Things Divine.

  1. The following dissertation concerning the Trinity, as the reader ought to be informed, has been written in order to guard against the sophistries of those who disdain to begin with faith, and are deceived by a crude and perverse love of reason. Now one class of such men endeavor to transfer to things incorporeal and spiritual the ideas they have formed, whether through experience of the bodily senses, or by natural human wit and diligent quickness, or by the aid of art, from things corporeal; so as to seek to measure and conceive of the former by the latter. Others, again, frame whatever sentiments they may have concerning God according to the nature or affections of the human mind; and through this error they govern their discourse, in disputing concerning God, by distorted and fallacious rules. While yet a third class strive indeed to transcend the whole creation, which doubtless is changeable, in order to raise their thought to the unchangeable substance, which is God; but being weighed down by the burden of mortality, whilst they both would seem to know what they do not, and cannot know what they would, preclude themselves from entering the very path of understanding, by an over-bold affirmation of their own presumptuous judgments; choosing rather not to correct their own opinion when it is perverse, than to change that which they have once defended. And, indeed, this is the common disease of all the three classes which I have mentioned,—viz., both of those who frame their thoughts of God according to things corporeal, and of those who do so according to the spiritual creature, such as is the soul; and of those who neither regard the body nor the spiritual creature, and yet think falsely about God; and are indeed so much the further from the truth, that nothing can be found answering to their conceptions, either in the body, or in the made or created spirit, or in the Creator Himself. For he who thinks, for instance, that God is white or red, is in error; and yet these things are found in the body. Again, he who thinks of God as now forgetting and now remembering, or anything of the same kind, is none the less in error; and yet these things are found in the mind. But he who thinks that God is of such power as to have generated Himself, is so much the more in error, because not only does God not so exist, but neither does the spiritual nor the bodily creature; for there is nothing whatever that generates its own existence.

  2. In order, therefore, that the human mind might be purged from falsities of this kind, Holy Scripture, which suits itself to babes has not avoided words drawn from any class of things really existing, through which, as by nourishment, our understanding might rise gradually to things divine and transcendent. For, in speaking of God, it has both used words taken from things corporeal, as when it says, “Hide me under the shadow of Thy wings;” and it has borrowed many things from the spiritual creature, whereby to signify that which indeed is not so, but must needs so be said: as, for instance, “I the Lord thy God am a jealous God;” and, “It repenteth me that I have made man.” But it has drawn no words whatever, whereby to frame either figures of speech or enigmatic sayings, from things which do not exist at all. And hence it is that they who are shut out from the truth by that third kind of error are more mischievously and emptily vain than their fellows; in that they surmise respecting God, what can neither be found in Himself nor in any creature. For divine Scripture is wont to frame, as it were, allurements for children from the things which are found in the creature; whereby, according to their measure, and as it were by steps, the affections of the weak may be moved to seek those things that are above, and to leave those things that are below. But the same Scripture rarely employs those things which are spoken properly of God, and are not found in any creature; as, for instance, that which was said to Moses, “I am that I am;” and, “I Am hath sent me to you.” For since both body and soul also are said in some sense to be, Holy Scripture certainly would not so express itself unless it meant to be understood in some special sense of the term. So, too, that which the Apostle says, “Who only hath immortality.” Since the soul also both is said to be, and is, in a certain manner immortal, Scripture would not say “only hath,” unless because true immortality is unchangeableness; which no creature can possess, since it belongs to the creator alone. So also James says, “Every good gift and every perfect gift is from above, and cometh down from the Father of Lights, with whom is no variableness, neither shadow of turning.” So also David, “Thou shall change them, and they shall be changed; but Thou art the same.”

  3. Further, it is difficult to contemplate and fully know the substance of God; who fashions things changeable, yet without any change in Himself, and creates things temporal, yet without any temporal movement in Himself. And it is necessary, therefore, to purge our minds, in order to be able to see ineffably that which is ineffable; whereto not having yet attained, we are to be nourished by faith, and led by such ways as are more suited to our capacity, that we may be rendered apt and able to comprehend it. And hence the Apostle says, that “in Christ indeed are hid all the treasures of wisdom and knowledge;” and yet has commended Him to us, as to babes in Christ, who, although already born again by His grace, yet are still carnal and psychical, not by that divine virtue wherein He is equal to the Father, but by that human infirmity whereby He was crucified. For he says, “I determined not to know anything among you, save Jesus Christ and Him crucified;” and then he continues, “And I was with you in weakness, and in fear, and in much trembling.” And a little after he says to them, “And I, brethren, could not speak unto you as unto spiritual, but as unto carnal, even as unto babes in Christ. I have fed you with milk, and not with meat: for hitherto ye were not able to bear it, neither yet now are ye able.” There are some who are angry at language of this kind, and think it is used in slight to themselves, and for the most part prefer rather to believe that they who so speak to them have nothing to say, than that they themselves cannot understand what they have said. And sometimes, indeed, we do allege to them, not certainly that account of the case which they seek in their inquiries about God,—because neither can they themselves receive it, nor can we perhaps either apprehend or express it,—but such an account of it as to demonstrate to them how incapable and utterly unfit they are to understand that which they require of us. But they, on their parts, because they do not hear what they desire, think that we are either playing them false in order to conceal our own ignorance, or speaking in malice because we grudge them knowledge; and so go away indignant and perturbed.

Caput II: In What Manner This Work Proposes to Discourse Concerning the Trinity.

  1. Wherefore, our Lord God helping, we will undertake to render, as far as we are able, that very account which they so importunately demand: viz., that the Trinity is the one and only and true God, and also how the Father, the Son, and the Holy Spirit are rightly said, believed, understood, to be of one and the same substance or essence; in such wise that they may not fancy themselves mocked by excuses on our part, but may find by actual trial, both that the highest good is that which is discerned by the most purified minds, and that for this reason it cannot be discerned or understood by themselves, because the eye of the human mind, being weak, is dazzled in that so transcendent light, unless it be invigorated by the nourishment of the righteousness of faith. First, however, we must demonstrate, according to the authority of the Holy Scriptures, whether the faith be so. Then, if God be willing and aid us, we may perhaps at least so far serve these talkative arguers—more puffed up than capable, and therefore laboring under the more dangerous disease—as to enable them to find something which they are not able to doubt, that so, in that case where they cannot find the like, they may be led to lay the fault to their own minds, rather than to the truth itself or to our reasonings; and thus, if there be anything in them of either love or fear towards God, they may return and begin from faith in due order: perceiving at length how healthful a medicine has been provided for the faithful in the holy Church, whereby a heedful piety, healing the feebleness of the mind, may render it able to perceive the unchangeable truth, and hinder it from falling headlong, through disorderly rashness, into pestilent and false opinion. Neither will I myself shrink from inquiry, if I am anywhere in doubt; nor be ashamed to learn, if I am anywhere in error.

Caput III: What Augustin Requests from His Readers. The Errors of Readers Dull of Comprehension Not to Be Ascribed to the Author.

  1. Further let me ask of my reader, wherever, alike with myself, he is certain, there to go on with me; wherever, alike with myself, he hesitates, there to join with me in inquiring; wherever he recognizes himself to be in error, there to return to me; wherever he recognizes me to be so, there to call me back: so that we may enter together upon the path of charity, and advance towards Him of whom it is said, “Seek His face evermore.” And I would make this pious and safe agreement, in the presence of our Lord God, with all who read my writings, as well in all other cases as, above all, in the case of those which inquire into the unity of the Trinity, of the Father and the Son and the Holy Spirit; because in no other subject is error more dangerous, or inquiry more laborious, or the discovery of truth more profitable. If, then, any reader shall say, This is not well said, because I do not understand it; such an one finds fault with my language, not with my faith: and it might perhaps in very truth have been put more clearly; yet no man ever so spoke as to be understood in all things by all men. Let him, therefore, who finds this fault with my discourse, see whether he can understand other men who have handled similar subjects and questions, when he does not understand me: and if he can, let him put down my book, or even, if he pleases, throw it away; and let him spend labor and time rather on those whom he understands. Yet let him not think on that account that I ought to have been silent, because I have not been able to express myself so smoothly and clearly to him as those do whom he understands. For neither do all things, which all men have written, come into the hands of all. And possibly some, who are capable of understanding even these our writings, may not find those more lucid works, and may meet with ours only. And therefore it is useful that many persons should write many books, differing in style but not in faith, concerning even the same questions, that the matter itself may reach the greatest number—some in one way, some in another. But if he who complains that he has not understood these things has never been able to comprehend any careful and exact reasonings at all upon such subjects, let him in that case deal with himself by resolution and study, that he may know better; not with me by quarrellings and wranglings, that I may hold my peace. Let him, again, who says, when he reads my book, Certainly I understand what is said, but it is not true, assert, if he pleases, his own opinion, and refute mine if he is able. And if he do this with charity and truth, and take the pains to make it known to me (if I am still alive), I shall then receive the most abundant fruit of this my labor. And if he cannot inform myself, most willing and glad should I be that he should inform those whom he can. Yet, for my part, “I meditate in the law of the Lord,” if not “day and night,” at least such short times as I can; and I commit my meditations to writing, lest they should escape me through forgetfulness; hoping by the mercy of God that He will make me hold steadfastly all truths of which I feel certain; “but if in anything I be otherwise minded, that He will himself reveal even this to me,” whether through secret inspiration and admonition, or through His own plain utterances, or through the reasonings of my brethren. This I pray for, and this my trust and desire I commit to Him, who is sufficiently able to keep those things which He has given me, and to render those which He has promised.

  2. I expect, indeed, that some, who are more dull of understanding, will imagine that in some parts of my books I have held sentiments which I have not held, or have not held those which I have. But their error, as none can be ignorant, ought not to be attributed to me, if they have deviated into false doctrine through following my steps without apprehending me, whilst I am compelled to pick my way through a hard and obscure subject: seeing that neither can any one, in any way, rightly ascribe the numerous and various errors of heretics to the holy testimonies themselves of the divine books; although all of them endeavor to defend out of those same Scriptures their own false and erroneous opinions. The law of Christ, that is, charity, admonishes me clearly, and commands me with a sweet constraint, that when men think that I have held in my books something false which I have not held, and that same falsehood displeases one and pleases another, I should prefer to be blamed by him who reprehends the falsehood, rather than praised by him who praises it. For although I, who never held the error, am not rightly blamed by the former, yet the error itself is rightly censured; whilst by the latter neither am I rightly praised, who am thought to have held that which the truth censures, nor the sentiment itself, which the truth also censures. Let us therefore essay the work which we have undertaken in the name of the Lord.

Caput IV: What the Doctrine of the Catholic Faith is Concerning the Trinity.

  1. All those Catholic expounders of the divine Scriptures, both Old and New, whom I have been able to read, who have written before me concerning the Trinity, Who is God, have purposed to teach, according to the Scriptures, this doctrine, that the Father, and the Son, and the Holy Spirit intimate a divine unity of one and the same substance in an indivisible equality; and therefore that they are not three Gods, but one God: although the Father hath begotten the Son, and so He who is the Father is not the Son; and the Son is begotten by the Father, and so He who is the Son is not the Father; and the Holy Spirit is neither the Father nor the Son, but only the Spirit of the Father and of the Son, Himself also co-equal with the Father and the Son, and pertaining to the unity of the Trinity. Yet not that this Trinity was born of the Virgin Mary, and crucified under Pontius Pilate, and buried, and rose again the third day, and ascended into heaven, but only the Son. Nor, again, that this Trinity descended in the form of a dove upon Jesus when He was baptized; nor that, on the day of Pentecost, after the ascension of the Lord, when “there came a sound from heaven, as of a rushing mighty wind,” the same Trinity “sat upon each of them with cloven tongues like as of fire,” but only the Holy Spirit. Nor yet that this Trinity said from heaven, “Thou art my Son,” whether when He was baptized by John, or when the three disciples were with Him in the mount, or when the voice sounded, saying, “I have both glorified it, and will glorify it again;” but that it was a word of the Father only, spoken to the Son; although the Father, and the Son, and the Holy Spirit, as they are indivisible, so work indivisibly. This is also my faith, since it is the Catholic faith.

Caput V: Of Difficulties Concerning the Trinity: in What Manner Three are One God, and How, Working Indivisibly, They Yet Perform Some Things Severally.

  1. Some persons, however, find a difficulty in this faith; when they hear that the Father is God, and the Son God, and the Holy Spirit God, and yet that this Trinity is not three Gods, but one God; and they ask how they are to understand this: especially when it is said that the Trinity works indivisibly in everything that God works, and yet that a certain voice of the Father spoke, which is not the voice of the Son; and that none except the Son was born in the flesh, and suffered, and rose again, and ascended into heaven; and that none except the Holy Spirit came in the form of a dove. They wish to understand how the Trinity uttered that voice which was only of the Father; and how the same Trinity created that flesh in which the Son only was born of the Virgin; and how the very same Trinity itself wrought that form of a dove, in which the Holy Spirit only appeared. Yet, otherwise, the Trinity does not work indivisibly, but the Father does some things, the Son other things, and the Holy Spirit yet others: or else, if they do some things together, some severally, then the Trinity is not indivisible. It is a difficulty, too, to them, in what manner the Holy Spirit is in the Trinity, whom neither the Father nor the Son, nor both, have begotten, although He is the Spirit both of the Father and of the Son. Since, then, men weary us with asking such questions, let us unfold to them, as we are able, whatever wisdom God’s gift has bestowed upon our weakness on this subject; neither “let us go on our way with consuming envy.” Should we say that we are not accustomed to think about such things, it would not be true; yet if we acknowledge that such subjects commonly dwell in our thoughts, carried away as we are by the love of investigating the truth, then they require of us, by the law of charity, to make known to them what we have herein been able to find out. “Not as though I had already attained, either were already perfect” (for, if the Apostle Paul, how much more must I, who lie far beneath his feet, count myself not to have apprehended!); but, according to my measure, “if I forget those things that are behind, and reach forth unto those things which are before, and press towards the mark for the prize of the high calling,” I am requested to disclose so much of the road as I have already passed, and the point to which I have reached, whence the course yet remains to bring me to the end. And those make the request, whom a generous charity compels me to serve. Needs must too, and God will grant that, in supplying them with matter to read, I shall profit myself also; and that, in seeking to reply to their inquiries, I shall myself likewise find that for which I was inquiring. Accordingly I have undertaken the task, by the bidding and help of the Lord my God, not so much of discoursing with authority respecting things I know already, as of learning those things by piously discoursing of them.

Caput VI: That the Son is Very God, of the Same Substance with the Father. Not Only the Father, But the Trinity, is Affirmed to Be Immortal. All Things are Not from the Father Alone, But Also from the Son. That the Holy Spirit is Very God, Equal with the Father and the Son.

  1. They who have said that our Lord Jesus Christ is not God, or not very God, or not with the Father the One and only God, or not truly immortal because changeable, are proved wrong by the most plain and unanimous voice of divine testimonies; as, for instance, “In the beginning was the Word, and the Word was with God, and the Word was God.” For it is plain that we are to take the Word of God to be the only Son of God, of whom it is afterwards said, “And the Word was made flesh, and dwelt among us,” on account of that birth of His incarnation, which was wrought in time of the Virgin. But herein is declared, not only that He is God, but also that He is of the same substance with the Father; because, after saying, “And the Word was God,” it is said also, “The same was in the beginning with God: all things were made by Him, and without Him was not anything made.” Not simply “all things;” but only all things that were made, that is; the whole creature. From which it appears clearly, that He Himself was not made, by whom all things were made. And if He was not made, then He is not a creature; but if He is not a creature, then He is of the same substance with the Father. For all substance that is not God is creature; and all that is not creature is God. And if the Son is not of the same substance with the Father, then He is a substance that was made: and if He is a substance that was made, then all things were not made by Him; but “all things were made by Him,” therefore He is of one and the same substance with the Father. And so He is not only God, but also very God. And the same John most expressly affirms this in his epistle: “For we know that the Son of God is come, and hath given us an understanding, that we may know the true God, and that we may be in His true Son Jesus Christ. This is the true God, and eternal life.”

  2. Hence also it follows by consequence, that the Apostle Paul did not say, “Who alone has immortality,” of the Father merely; but of the One and only God, which is the Trinity itself. For that which is itself eternal life is not mortal according to any changeableness; and hence the Son of God, because “He is Eternal Life,” is also Himself understood with the Father, where it is said, “Who only hath immortality.” For we, too, are made partakers of this eternal life, and become, in our own measure, immortal. But the eternal life itself, of which we are made partakers, is one thing; we ourselves, who, by partaking of it, shall live eternally, are another. For if He had said, “Whom in His own time the Father will show, who is the blessed and only Potentate, the King of kings, and Lord of lords; who only hath immortality;” not even so would it be necessarily understood that the Son is excluded. For neither has the Son separated the Father from Himself, because He Himself, speaking elsewhere with the voice of wisdom (for He Himself is the Wisdom of God), says, “I alone compassed the circuit of heaven.” And therefore so much the more is it not necessary that the words, “Who hath immortality,” should be understood of the Father alone, omitting the Son; when they are said thus: “That thou keep this commandment without spot, unrebukeable, until the appearing of our Lord Jesus Christ: whom in His own time He will show, who is the blessed and only Potentate, the King of kings, and Lord of lords; who only hath immortality, dwelling in the light which no man can approach unto; whom no man hath seen, nor can see: to whom be honor and power everlasting. Amen.” In which words neither is the Father specially named, nor the Son, nor the Holy Spirit; but the blessed and only Potentate, the King of kings, and Lord of lords; that is, the One and only and true God, the Trinity itself.

  3. But perhaps what follows may interfere with this meaning; because it is said, “Whom no man hath seen, nor can see:” although this may also be taken as belonging to Christ according to His divinity, which the Jews did not see, who yet saw and crucified Him in the flesh; whereas His divinity can in no wise be seen by human sight, but is seen with that sight with which they who see are no longer men, but beyond men. Rightly, therefore, is God Himself, the Trinity, understood to be the “blessed and only Potentate,” who “shows the coming of our Lord Jesus Christ in His own time.” For the words, “Who only hath immortality,” are said in the same way as it is said, “Who only doeth wondrous things.” And I should be glad to know of whom they take these words to be said. If only of the Father, how then is that true which the Son Himself says, “For what things soever the Father doeth, these also doeth the Son likewise?” Is there any, among wonderful works, more wonderful than to raise up and quicken the dead? Yet the same Son saith, “As the Father raiseth up the dead, and quickeneth them, even so the Son quickeneth whom He will.” How, then, does the Father alone “do wondrous things,” when these words allow us to understand neither the Father only, nor the Son only, but assuredly the one only true God, that is, the Father, and the Son, and the Holy Spirit?

  4. Also, when the same apostle says, “But to us there is but one God, the Father, of whom are all things, and we in Him; and one Lord Jesus Christ, by whom are all things, and we by Him,” who can doubt that he speaks of all things which are created; as does John, when he says, “All things were made by Him”? I ask, therefore, of whom he speaks in another place: “For of Him, and through Him, and in Him, are all things: to whom be glory for ever. Amen.” For if of the Father, and the Son, and the Holy Spirit, so as to assign each clause severally to each person: of Him, that is to say, of the Father; through Him, that is to say, through the Son; in Him, that is to say, in the Holy Spirit,—it is manifest that the Father, and the Son, and the Holy Spirit is one God, inasmuch as the words continue in the singular number, “To whom be glory for ever.” For at the beginning of the passage he does not say, “O the depth of the riches both of the wisdom and knowledge” of the Father, or of the Son, or of the Holy Spirit, but “of the wisdom and knowledge of God!” “How unsearchable are His judgments, and His ways past finding out! For who hath known the mind of the Lord? or who hath been His counsellor? Or who hath first given to Him and it shall be recompensed unto him again? For of Him, and through Him, and in Him, are all things: to whom be glory for ever. Amen.” But if they will have this to be understood only of the Father, then in what way are all things by the Father, as is said here; and all things by the Son, as where it is said to the Corinthians, “And one Lord Jesus Christ, by whom are all things,” and as in the Gospel of John, “All things were made by Him?” For if some things were made by the Father, and some by the Son, then all things were not made by the Father, nor all things by the Son; but if all things were made by the Father, and all things by the Son, then the same things were made by the Father and by the Son. The Son, therefore, is equal with the Father, and the working of the Father and the Son is indivisible. Because if the Father made even the Son, whom certainly the Son Himself did not make, then all things were not made by the Son; but all things were made by the Son: therefore He Himself was not made, that with the Father He might make all things that were made. And the apostle has not refrained from using the very word itself, but has said most expressly, “Who, being in the form of God, thought it not robbery to be equal with God;” using here the name of God specially of the Father; as elsewhere, “But the head of Christ is God.”

  5. Similar evidence has been collected also concerning the Holy Spirit, of which those who have discussed the subject before ourselves have most fully availed themselves, that He too is God, and not a creature. But if not a creature, then not only God (for men likewise are called gods), but also very God; and therefore absolutely equal with the Father and the Son, and in the unity of the Trinity consubstantial and co-eternal. But that the Holy Spirit is not a creature is made quite plain by that passage above all others, where we are commanded not to serve the creature, but the Creator; not in the sense in which we are commanded to “serve” one another by love, which is in Greek δουλεύειν, but in that in which God alone is served, which is in Greek λατρεύειν. From whence they are called idolaters who tender that service to images which is due to God. For it is this service concerning which it is said, “Thou shalt worship the Lord thy God, and Him only shalt thou serve.” For this is found also more distinctly in the Greek Scriptures, which have λατρεύσεις. Now if we are forbidden to serve the creature with such a service, seeing that it is written, “Thou shalt worship the Lord thy God, and Him only shalt thou serve” (and hence, too, the apostle repudiates those who worship and serve the creature more than the Creator), then assuredly the Holy Spirit is not a creature, to whom such a service is paid by all the saints; as says the apostle, “For we are the circumcision, which serve the Spirit of God,” which is in the Greek λατρεύοντες. For even most Latin copies also have it thus, “We who serve the Spirit of God;” but all Greek ones, or almost all, have it so. Although in some Latin copies we find, not “We worship the Spirit of God,” but, “We worship God in the Spirit.” But let those who err in this case, and refuse to give up to the more weighty authority, tell us whether they find this text also varied in the mss.: “Know ye not that your body is the temple of the Holy Ghost, which is in you, which ye have of God?” Yet what can be more senseless or more profane, than that any one should dare to say that the members of Christ are the temple of one who, in their opinion, is a creature inferior to Christ? For the apostle says in another place, “Your bodies are members of Christ.” But if the members of Christ are also the temple of the Holy Spirit, then the Holy Spirit is not a creature; because we must needs owe to Him, of whom our body is the temple, that service wherewith God only is to be served, which in Greek is called λατρεία. And accordingly the apostle says, “Therefore glorify God in your body.”

Caput VII: In What Manner the Son is Less Than the Father, and Than Himself.

  1. In these and like testimonies of the divine Scriptures, by free use of which, as I have said, our predecessors exploded such sophistries or errors of the heretics, the unity and equality of the Trinity are intimated to our faith. But because, on account of the incarnation of the Word of God for the working out of our salvation, that the man Christ Jesus might be the Mediator between God and men, many things are so said in the sacred books as to signify, or even most expressly declare, the Father to be greater than the Son; men have erred through a want of careful examination or consideration of the whole tenor of the Scriptures, and have endeavored to transfer those things which are said of Jesus Christ according to the flesh, to that substance of His which was eternal before the incarnation, and is eternal. They say, for instance, that the Son is less than the Father, because it is written that the Lord Himself said, “My Father is greater than I.” But the truth shows that after the same sense the Son is less also than Himself; for how was He not made less also than Himself, who “emptied Himself, and took upon Him the form of a servant?” For He did not so take the form of a servant as that He should lose the form of God, in which He was equal to the Father. If, then, the form of a servant was so taken that the form of God was not lost, since both in the form of a servant and in the form of God He Himself is the same only-begotten Son of God the Father, in the form of God equal to the Father, in the form of a servant the Mediator between God and men, the man Christ Jesus; is there any one who cannot perceive that He Himself in the form of God is also greater than Himself, but yet likewise in the form of a servant less than Himself? And not, therefore, without cause the Scripture says both the one and the other, both that the Son is equal to the Father, and that the Father is greater than the Son. For there is no confusion when the former is understood as on account of the form of God, and the latter as on account of the form of a servant. And, in truth, this rule for clearing the question through all the sacred Scriptures is set forth in one chapter of an epistle of the Apostle Paul, where this distinction is commended to us plainly enough. For he says, “Who, being in the form of God, thought it not robbery to be equal with God; but emptied Himself, and took upon Him the form of a servant, and was made in the likeness of men: and was found in fashion as a man.” The Son of God, then, is equal to God the Father in nature, but less in “fashion.” For in the form of a servant which He took He is less than the Father; but in the form of God, in which also He was before He took the form of a servant, He is equal to the Father. In the form of God He is the Word, “by whom all things are made;” but in the form of a servant He was “made of a woman, made under the law, to redeem them that were under the law.” In like manner, in the form of God He made man; in the form of a servant He was made man. For if the Father alone had made man without the Son, it would not have been written, “Let us make man in our image, after our likeness.” Therefore, because the form of God took the form of a servant, both is God and both is man; but both God, on account of God who takes; and both man, on account of man who is taken. For neither by that taking is the one of them turned and changed into the other: the Divinity is not changed into the creature, so as to cease to be Divinity; nor the creature into Divinity, so as to cease to be creature.

Caput VIII: The Texts of Scripture Explained Respecting the Subjection of the Son to the Father, Which Have Been Misunderstood. Christ Will Not So Give Up the Kingdom to the Father, as to Take It Away from Himself. The Beholding Him is the Promised End of All Actions. The Holy Spirit is Sufficient to Our Blessedness Equally with the Father.

As for that which the apostle says, “And when all things shall be subdued unto Him, then shall the Son also Himself be subject unto Him that put all things under Him:” either the text has been so turned, lest any one should think that the “fashion” of Christ, which He took according to the human creature, was to be transformed hereafter into the Divinity, or (to express it more precisely) the Godhead itself, who is not a creature, but is the unity of the Trinity,—a nature incorporeal, and unchangeable, and consubstantial, and co-eternal with itself; or if any one contends, as some have thought, that the text, “Then shall the Son also Himself be subject unto Him that put all things under Him,” is so turned in order that one may believe that very “subjection” to be a change and conversion hereafter of the creature into the substance or essence itself of the Creator, that is, that that which had been the substance of a creature shall become the substance of the Creator;—such an one at any rate admits this, of which in truth there is no possible doubt, that this had not yet taken place, when the Lord said, “My Father is greater than I.” For He said this not only before He ascended into heaven, but also before He had suffered, and had risen from the dead. But they who think that the human nature in Him is to be changed and converted into the substance of the Godhead, and that it was so said, “Then shall the Son also Himself be subject unto Him that put all things under Him,”—as if to say, Then also the Son of man Himself, and the human nature taken by the Word of God, shall be changed into the nature of Him who put all things under Him,—must also think that this will then take place, when, after the day of judgment, “He shall have delivered up the kingdom to God, even the Father.” And hence even still, according to this opinion, the Father is greater than that form of a servant which was taken of the Virgin. But if some affirm even further, that the man Christ Jesus has already been changed into the substance of God, at least they cannot deny that the human nature still remained, when He said before His passion, “For my Father is greater than I;” whence there is no question that it was said in this sense, that the Father is greater than the form of a servant, to whom in the form of God the Son is equal. Nor let any one, hearing what the apostle says, “But when He saith all things are put under Him, it is manifest that He is excepted which did put all things under Him,” think the words, that He hath put all things under the Son, to be so understood of the Father, as that He should not think that the Son Himself put all things under Himself. For this the apostle plainly declares, when he says to the Philippians, “For our conversation is in heaven; from whence also we look for the Saviour, the Lord Jesus Christ: who shall change our vile body, that it may be fashioned like unto His glorious body, according to the working whereby He is able even to subdue all things unto Himself.” For the working of the Father and of the Son is indivisible. Otherwise, neither hath the Father Himself put all things under Himself, but the Son hath put all things under Him, who delivers the kingdom to Him, and puts down all rule and all authority and power. For these words are spoken of the Son: “When He shall have delivered up,” says the apostle, “the kingdom to God, even the Father; when He shall have put down all rule, and all authority, and all power.” For the same that puts down, also makes subject.

  2. Neither may we think that Christ shall so give up the kingdom to God, even the Father, as that He shall take it away from Himself. For some vain talkers have thought even this. For when it is said, “He shall have delivered up the kingdom to God, even the Father,” He Himself is not excluded; because He is one God together with the Father. But that word “until” deceives those who are careless readers of the divine Scriptures, but eager for controversies. For the text continues, “For He must reign, until He hath put all enemies under His feet;” as though, when He had so put them, He would no more reign. Neither do they perceive that this is said in the same way as that other text, “His heart is established: He shall not be afraid, until He see His desire upon His enemies.” For He will not then be afraid when He has seen it. What then means, “When He shall have delivered up the kingdom to God, even the Father,” as though God and the Father has not the kingdom now? But because He is hereafter to bring all the just, over whom now, living by faith, the Mediator between God and men, the man Christ Jesus, reigns, to that sight which the same apostle calls “face to face;” therefore the words, “When He shall have delivered up the kingdom to God, even the Father,” are as much as to say, When He shall have brought believers to the contemplation of God, even the Father. For He says, “All things are delivered unto me of my Father: and 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.” The Father will then be revealed by the Son, “when He shall have put down all rule, and all authority, and all power;” that is, in such wise that there shall be no more need of any economy of similitudes, by means of angelic rulers, and authorities, and powers. Of whom that is not unfitly understood, which is said in the Song of Songs to the bride, “We will make thee borders of gold, with studs of silver, while the King sitteth at His table;” that is, as long as Christ is in His secret place: since “your life is hid with Christ in God; when Christ, who is our life, shall appear, then shall ye also appear with Him in glory.” Before which time, “we see now through a glass, in an enigma,” that is, in similitudes, “but then face to face.”

  3. For this contemplation is held forth to us as the end of all actions, and the everlasting fullness of joy. For “we are the sons of God; and it doth not yet appear what we shall be: but we know that, when He shall appear, we shall be like Him; for we shall see Him as He is.” For that which He said to His servant Moses, “I am that I am; thus shalt thou say to the children of Israel, I Am hath sent me to you;” this it is which we shall contemplate when we shall live in eternity. For so it is said, “And this is life eternal, that they might know Thee, the only true God, and Jesus Christ, whom Thou hast sent.” This shall be when the Lord shall have come, and “shall have brought to light the hidden things of darkness;” when the darkness of this present mortality and corruption shall have passed away. Then will be our morning, which is spoken of in the Psalm, “In the morning will I direct my prayer unto Thee, and will contemplate Thee.” Of this contemplation I understand it to be said, “When He shall have delivered up the kingdom to God, even the Father;” that is, when He shall have brought the just, over whom now, living by faith, the Mediator between God and man, the man Christ Jesus, reigns, to the contemplation of God, even the Father. If herein I am foolish, let him who knows better correct me; to me at least the case seems as I have said. For we shall not seek anything else, when we shall have come to the contemplation of Him. But that contemplation is not yet, so long as our joy is in hope. For “hope that is seen is not hope: for what a man seeth, why doth he yet hope for? But if we hope for that we see not, then do we with patience wait for it,” viz. “as long as the King sitteth at His table.” Then will take place that which is written, “In Thy presence is fullness of joy.” Nothing more than that joy will be required; because there will be nothing more than can be required. For the Father will be manifested to us, and that will suffice for us. And this much Philip had well understood, so that he said to the Lord, “Show us the Father, and it sufficeth us.” But he had not yet understood that he himself was able to say this very same thing in this way also: Lord, show Thyself to us, and it sufficeth us. For, that he might understand this, the Lord replied to him, “Have I been so long time with you, and yet hast thou not known me, Philip? he that hath seen me hath seen the Father.” But because He intended him, before he could see this, to live by faith, He went on to say, “Believest thou not that I am in the Father, and the Father in me?” For “while we are at home in the body, we are absent from the Lord: for we walk by faith, not by sight.” For contemplation is the recompense of faith, for which recompense our hearts are purified by faith; as it is written, “Purifying their hearts by faith.” And that our hearts are to be purified for this contemplation, is proved above all by this text, “Blessed are the pure in heart, for they shall see God.” And that this is life eternal, God says in the Psalm, “With long life will I satisfy him, and show him my salvation.” Whether, therefore, we hear, Show us the Son; or whether we hear, Show us the Father; it is even all one, since neither can be manifested without the other. For they are one, as He also Himself says, “My Father and I are one.” Finally, on account of this very indivisibility, it suffices that sometimes the Father alone, or the Son alone, should be named, as hereafter to fill us with the joy of His countenance.

  4. Neither is the Spirit of either thence excluded, that is, the Spirit of the Father and of the Son; which Holy Spirit is specially called “the Spirit of truth, whom the world cannot receive.” For to have the fruition of God the Trinity, after whose image we are made, is indeed the fullness of our joy, than which there is no greater. On this account the Holy Spirit is sometimes spoken of as if He alone sufficed to our blessedness: and He does alone so suffice, because He cannot be divided from the Father and the Son; as the Father alone is sufficient, because He cannot be divided from the Son and the Holy Spirit; and the Son alone is sufficient because He cannot be divided from the Father and the Holy Spirit. For what does He mean by saying, “If ye love me, keep my commandments; and I will pray the Father, and He shall give you another Comforter, that He may abide with you for ever; even the Spirit of truth, whom the world cannot receive,” that is, the lovers of the world? For “the natural man receiveth not the things of the Spirit of God.” But it may perhaps seem, further, as if the words, “And I will pray the Father, and He shall give you another Comforter,” were so said as if the Son alone were not sufficient. And that place so speaks of the Spirit, as if He alone were altogether sufficient: “When He, the Spirit of truth, is come, He will guide you into all truth.” Pray, therefore, is the Son here excluded, as if He did not teach all truth, or as if the Holy Spirit were to fill up that which the Son could not fully teach? Let them say then, if it pleases them, that the Holy Spirit is greater than the Son, whom they are wont to call less. Or is it, forsooth, because it is not said, He alone,—or, No one else except Himself—will guide you into all truth, that they allow that the Son also may be believed to teach together with Him? In that case the apostle has excluded the Son from knowing those things which are of God, where he says, “Even so the things of God knoweth no one, but the Spirit of God:” so that these perverse men might, upon this ground, go on to say that none but the Holy Spirit teaches even the Son the things of God, as the greater teaches the less; to whom the Son Himself ascribes so much as to say, “But because I have said these things unto you, sorrow hath filled your heart. Nevertheless I tell you the truth; it is expedient for you that I go away: for if I go not away, the Comforter will not come unto you.”

Caput IX: All are Sometimes Understood in One Person.

But this is said, not on account of any inequality of the Word of God and of the Holy Spirit, but as though the presence of the Son of man with them would be a hindrance to the coming of Him, who was not less, because He did not “empty Himself, taking upon Him the form of a servant,” as the Son did. It was necessary, then, that the form of a servant should be taken away from their eyes, because, through gazing upon it, they thought that alone which they saw to be Christ. Hence also is that which is said, “If ye loved me, ye would rejoice because I said, ‘I go unto the Father; for my Father is greater than I:’” that is, on that account it is necessary for me to go to the Father, because, whilst you see me thus, you hold me to be less than the Father through that which you see; and so, being taken up with the creature and the “fashion” which I have taken upon me, you do not perceive the equality which I have with the Father. Hence, too, is this: “Touch me not; for I am not yet ascended to my Father.” For touch, as it were, puts a limit to their conception, and He therefore would not have the thought of the heart, directed towards Himself, to be so limited as that He should be held to be only that which He seemed to be. But the “ascension to the Father” meant, so to appear as He is equal to the Father, that the limit of the sight which sufficeth us might be attained there. Sometimes also it is said of the Son alone, that He himself sufficeth, and the whole reward of our love and longing is held forth as in the sight of Him. For so it is said, “He that hath my commandments, and keepeth them, he it is that loveth me; and he that loveth me shall be loved of my Father; and I will love him, and will manifest myself to him.” Pray, because He has not here said, And I will show the Father also to him, has He therefore excluded the Father? On the contrary, because it is true, “I and my Father are one,” when the Father is manifested, the Son also, who is in Him, is manifested; and when the Son is manifested, the Father also, who is in Him, is manifested. As, therefore, when it is said, “And I will manifest myself to him,” it is understood that He manifests also the Father; so likewise in that which is said, “When He shall have delivered up the kingdom to God, even the Father,” it is understood that He does not take it away from Himself; since, when He shall bring believers to the contemplation of God, even the Father, doubtless He will bring them to the contemplation of Himself, who has said, “And I will manifest myself to him.” And so, consequently, when Judas had said to Him, “Lord, how is it that Thou wilt manifest Thyself unto us, and not unto the world?” Jesus answered and said to him, “If a man love me, he will keep my words: and my Father will love him, and we will come unto him, and make our abode with him.” Behold, that He manifests not only Himself to him by whom He is loved, because He comes to him together with the Father, and abides with him.

  1. Will it perhaps be thought, that when the Father and the Son make their abode with him who loves them, the Holy Spirit is excluded from that abode? What, then, is that which is said above of the Holy Spirit: “Whom the world cannot receive, because it seeth Him not: but ye know Him; for He abideth with you, and is in you”? He, therefore, is not excluded from that abode, of whom it is said, “He abideth with you, and is in you;” unless, perhaps, any one be so senseless as to think, that when the Father and the Son have come that they may make their abode with him who loves them, the Holy Spirit will depart thence, and (as it were) give place to those who are greater. But the Scripture itself meets this carnal idea; for it says a little above: “I will pray the Father, and He shall give you another Comforter, that He may abide with you for ever.” He will not therefore depart when the Father and the Son come, but will be in the same abode with them eternally; because neither will He come without them, nor they without Him. But in order to intimate the Trinity, some things are separately affirmed, the Persons being also each severally named; and yet are not to be understood as though the other Persons were excluded, on account of the unity of the same Trinity and the One substance and Godhead of the Father and of the Son and of the Holy Spirit.

Caput X: In What Manner Christ Shall Deliver Up the Kingdom to God, Even the Father. The Kingdom Having Been Delivered to God, Even the Father, Christ Will Not Then Make Intercession for Us.

  1. Our Lord Jesus Christ, therefore, will so deliver up the kingdom to God, even the Father, Himself not being thence excluded, nor the Holy Spirit, when He shall bring believers to the contemplation of God, wherein is the end of all good actions, and everlasting rest, and joy which never will be taken from us. For He signifies this in that which He says: “I will see you again, and your heart shall rejoice; and your joy no man taketh from you.” Mary, sitting at the feet of the Lord, and earnestly listening to His word, foreshowed a similitude of this joy; resting as she did from all business, and intent upon the truth, according to that manner of which this life is capable, by which, however, to prefigure that which shall be for eternity. For while Martha, her sister, was cumbered about necessary business, which, although good and useful, yet, when rest shall have succeeded, is to pass away, she herself was resting in the word of the Lord. And so the Lord replied to Martha, when she complained that her sister did not help her: “Mary hath chosen the best part, which shall not be taken away from her.” He did not say that Martha was acting a bad part; but that “best part that shall not be taken away.” For that part which is occupied in the ministering to a need shall be “taken away” when the need itself has passed away. Since the reward of a good work that will pass away is rest that will not pass away. In that contemplation, therefore, God will be all in all; because nothing else but Himself will be required, but it will be sufficient to be enlightened by and to enjoy Him alone. And so he in whom “the Spirit maketh intercession with groanings which cannot be uttered,” says, “One thing have I desired of the Lord, that I will seek after; that I may dwell in the house of the Lord all the days of my life, to contemplate the beauty of the Lord.” For we shall then contemplate God, the Father and the Son and the Holy Spirit, when the Mediator between God and men, the man Christ Jesus, shall have delivered up the kingdom to God, even the Father, so as no longer to make intercession for us, as our Mediator and Priest, Son of God and Son of man; but that He Himself too, in so far as He is a Priest that has taken the form of a servant for us, shall be put under Him who has put all things under Him, and under whom He has put all things: so that, in so far as He is God, He with Him will have put us under Himself; in so far as He is a Priest, He with us will be put under Him. And therefore as the [incarnate] Son is both God and man, it is rather to be said that the manhood in the Son is another substance [from the Son], than that the Son in the Father [is another substance from the Father]; just as the carnal nature of my soul is more another substance in relation to my soul itself, although in one and the same man, than the soul of another man is in relation to my soul.

  2. When, therefore, He “shall have delivered up the kingdom to God, even the Father,”—that is, when He shall have brought those who believe and live by faith, for whom now as Mediator He maketh intercession, to that contemplation, for the obtaining of which we sigh and groan, and when labor and groaning shall have passed away,—then, since the kingdom will have been delivered up to God, even the Father, He will no more make intercession for us. And this He signifies, when He says: “These things have I spoken unto you in similitudes; but the time cometh when I shall no more speak unto you in similitudes, but I shall declare to you plainly of the Father:” that is, they will not then be “similitudes,” when the sight shall be “face to face.” For this it is which He says, “But I will declare to you plainly of the Father;” as if He said I will plainly show you the Father. For He says, I will “declare” to you, because He is His word. For He goes on to say, “At that day ye shall ask in my name; and I say not unto you, that I will pray the Father for you: for the Father Himself loveth you, because ye have loved me, and have believed that I came out from God. I came forth from the Father, and am come into the world: again, I leave the world, and go to the Father.” What is meant by “I came forth from the Father,” unless this, that I have not appeared in that form in which I am equal to the Father, but otherwise, that is, as less than the Father, in the creature which I have taken upon me? And what is meant by “I am come into the world,” unless this, that I have manifested to the eyes even of sinners who love this world, the form of a servant which I took, making myself of no reputation? And what is meant by “Again, I leave the world,” unless this, that I take away from the sight of the lovers of this world that which they have seen? And what is meant by “I go to the Father,” unless this, that I teach those who are my faithful ones to understand me in that being in which I am equal to the Father? Those who believe this will be thought worthy of being brought by faith to sight, that is, to that very sight, in bringing them to which He is said to “deliver up the kingdom to God, even the Father.” For His faithful ones, whom He has redeemed with His blood, are called His kingdom, for whom He now intercedes; but then, making them to abide in Himself there, where He is equal to the Father, He will no longer pray the Father for them. “For,” He says, “the Father Himself loveth you.” For indeed He “prays,” in so far as He is less than the Father; but as He is equal with the Father, He with the Father grants. Wherefore He certainly does not exclude Himself from that which He says, “The Father Himself loveth you;” but He means it to be understood after that manner which I have above spoken of, and sufficiently intimated,—namely, that for the most part each Person of the Trinity is so named, that the other Persons also may be understood. Accordingly, “For the Father Himself loveth you,” is so said that by consequence both the Son and the Holy Spirit also may be understood: not that He does not now love us, who spared not His own Son, but delivered Him up for us all; but God loves us, such as we shall be, not such as we are, for such as they are whom He loves, such are they whom He keeps eternally; which shall then be, when He who now maketh intercession for us shall have “delivered up the kingdom to God, even the Father,” so as no longer to ask the Father, because the Father Himself loveth us. But for what deserving, except of faith, by which we believe before we see that which is promised? For by this faith we shall arrive at sight; so that He may love us, being such, as He loves us in order that we may become; and not such, as He hates us because we are, and exhorts and enables us to wish not to be always.

Caput XI: By What Rule in the Scriptures It is Understood that the Son is Now Equal and Now Less.

  1. Wherefore, having mastered this rule for interpreting the Scriptures concerning the Son of God, that we are to distinguish in them what relates to the form of God, in which He is equal to the Father, and what to the form of a servant which He took, in which He is less than the Father; we shall not be disquieted by apparently contrary and mutually repugnant sayings of the sacred books. For both the Son and the Holy Spirit, according to the form of God, are equal to the Father, because neither of them is a creature, as we have already shown: but according to the form of a servant He is less than the Father, because He Himself has said, “My Father is greater than I;” and He is less than Himself, because it is said of Him, He emptied Himself;” and He is less than the Holy Spirit, because He Himself says, “Whosoever speaketh a word against the Son of man, it shall be forgiven him; but whosoever speaketh against the Holy Ghost, it shall not be forgiven Him.” And in the Spirit too He wrought miracles, saying: “But if I with the Spirit of God cast out devils, no doubt the kingdom of God is come upon you.” And in Isaiah He says,—in the lesson which He Himself read in the synagogue, and showed without a scruple of doubt to be fulfilled concerning Himself,—“The Spirit of the Lord God,” He says, “is upon me: because He hath anointed me to preach good tidings unto the meek He hath sent me to proclaim liberty to the captives,” etc.: for the doing of which things He therefore declares Himself to be “sent,” because the Spirit of God is upon Him. According to the form of God, all things were made by Him; according to the form of a servant, He was Himself made of a woman, made under the law. According to the form of God, He and the Father are one; according to the form of a servant, He came not to do His own will, but the will of Him that sent Him. According to the form of God, “As the Father hath life in Himself, so hath He given to the Son to have life in Himself;” according to the form of a servant, His “soul is sorrowful even unto death;” and, “O my Father,” He says, “if it be possible, let this cup pass from me.” According to the form of God, “He is the True God, and eternal life;” according to the form of a servant, “He became obedient unto death, even the death of the cross.”—23. According to the form of God, all things that the Father hath are His, and “All mine,” He says, “are Thine, and Thine are mine;” according to the form of a servant, the doctrine is not His own, but His that sent Him.
