Augustine, Hypostatic Union & Christ as Lesser than Himself

The quotations from St. Augustine are taken from On the Trinity, Book 1. Augustine will cite texts such as 1 John 5:20, where Jesus is called the true God and eternal life, to prove that Christ is one divine Person who operates in/by/through two natures since he is the God-Man. He will explain that Jesus, by virtue of becoming Man, not only became lesser than the Father and the Spirit, but also became lesser than himself. St. Augustine employs Philippians 2:5-8 to show that there are things that apply to Jesus in regards to his being in the form of God, and others that relate to the form of a servant that he took upon. All emphasis will be mine.

Chapter 7.— In What Manner the Son is Less Than the Father, and Than Himself.

14. 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...

Chapter 11.— By What Rule in the Scriptures It is Understood that the Son is Now Equal and Now Less.

22. 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 speaks a word against the Son of man, it shall be forgiven him; but whosoever speaks 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 has 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 has anointed me to preach good tidings unto the meek He has 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 has life in Himself, so has 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 has are His, and All mine, He says, are Yours, and Yours are mine; according to the form of a servant, the doctrine is not His own, but His that sent Him.

Chapter 12.— In What Manner the Son is Said Not to Know the Day and the Hour Which the Father Knows. Some Things Said of Christ According to the Form of God, Other Things According to the Form of a Servant. In What Way It is of Christ to Give the Kingdom, in What Not of Christ. Christ Will Both Judge and Not Judge.

Again, Of that day and that hour knows no man, no, not the angels which are in heaven; neither the Son, but the Father. For He is ignorant of this, as making others ignorant; that is, in that He did not so know as at that time to show His disciples: as it was said to Abraham, Now I know that you fear God, that is, now I have caused you to know it; because he himself, being tried in that temptation, became known to himself. For He was certainly going to tell this same thing to His disciples at the fitting time; speaking of which yet future as if past, He says, Henceforth I call you not servants, but friends; for the servant knows not what his Lord does: but I have called you friends; for all things that I have heard of my Father I have made known unto you; which He had not yet done, but spoke as though He had already done it, because He certainly would do it. For He says to the disciples themselves, I have yet many things to say unto you; but you cannot bear them now. Among which is to be understood also, Of the day and hour. For the apostle also says, I determined not to know anything among you, save Jesus Christ, and Him crucified; because he was speaking to those who were not able to receive higher things concerning the Godhead of Christ. To whom also a little while after he says, I could not speak unto you as unto spiritual, but as unto carnal. He was ignorant, therefore, among them of that which they were not able to know from him. And that only he said that he knew, which it was fitting that they should know from him. In short, he knew among the perfect what he knew not among babes; for he there says: We speak wisdom among them that are perfect. For a man is said not to know what he hides, after that kind of speech, after which a ditch is called blind which is hidden. For the Scriptures do not use any other kind of speech than may be found in use among men, because they speak to men.

24. According to the form of God, it is said Before all the hills He begot me, that is, before all the loftinesses of things created and, Before the dawn I begot You, that is, before all times and temporal things: but according to the form of a servant, it is said, The Lord created me in the beginning of His ways. Because, according to the form of God, He said, I am the truth; and according to the form of a servant, I am the way. For, because He Himself, being the first-begotten of the dead, made a passage to the kingdom of God to life eternal for His Church, to which He is so the Head as to make the body also immortal, therefore He was created in the beginning of the ways of God in His work. For, according to the form of God, He is the beginning, that also speaks unto us, in which beginning God created the heaven and the earth; but according to the form of a servant, He is a bridegroom coming out of His chamber. According to the form of God, He is the first-born of every creature, and He is before all things and by him all things consist; according to the form of a servant, He is the head of the body, the Church. According to the form of God, He is the Lord of glory. From which it is evident that He Himself glorifies His saints: for, Whom He did predestinate, them He also called; and whom He called, them He also justified; and whom He justified, them He also glorified. Of Him accordingly it is said, that He justifies the ungodly; of Him it is said, that He is just and a justifier. If, therefore, He has also glorified those whom He has justified, He who justifies, Himself also glorifies; who is, as I have said, the Lord of glory. Yet, according to the form of a servant, He replied to His disciples, when inquiring about their own glorification: To sit on my right hand and on my left is not mine to give, but [it shall be given to them] for whom it is prepared by my Father.

25. But that which is prepared by His Father is prepared also by the Son Himself, because He and the Father are one. For we have already shown, by many modes of speech in the divine Scriptures, that, in this Trinity, what is said of each is also said of all, on account of the indivisible working of the one and same substance. As He also says of the Holy Spirit, If I depart, I will send Him unto you. He did not say, We will send; but in such way as if the Son only should send Him, and not the Father; while yet He says in another place, These things have I spoken unto you, being yet present with you; but the Comforter, which is the Holy Ghost, whom the Father will send in my name, He shall teach you all things. Here again it is so said as if the Son also would not send Him, but the Father only. As therefore in these texts, so also where He says, But for them for whom it is prepared by my Father, He meant it to be understood that He Himself, with the Father, prepares seats of glory for those for whom He will. But some one may say: There, when He spoke of the Holy Spirit, He so says that He Himself will send Him, as not to deny that the Father will send Him; and in the other place, He so says that the Father will send Him, as not to deny that He will do so Himself; but here He expressly says, It is not mine to give, and so goes on to say that these things are prepared by the Father. But this is the very thing which we have already laid down to be said according to the form of a servant: viz., that we are so to understand It is not mine to give, as if it were said, This is not in the power of man to give; that so He may be understood to give it through that wherein He is God equal to the Father. It is not mine, He says, to give; that is, I do not give these things by human power, but to those for whom it is prepared by my Father; but then take care you understand also, that if all things which the Father has are mine, then this certainly is mine also, and I with the Father have prepared these things.

26. For I ask again, in what manner this is said, If any man hear not my words, I will not judge him? For perhaps He has said here, I will not judge him, in the same sense as there, It is not mine to give. But what follows here? I came not, He says, to judge the world, but to save the world; and then He adds, He that rejects me, and receives not my words, has one that judges him. Now here we should understand the Father, unless He had added, The word that I have spoken, the same shall judge him in the last day. Well, then, will neither the Son judge, because He says, I will not judge him, nor the Father, but the word which the Son has spoken? Nay, but hear what yet follows: For I, He says, have not spoken of myself; but the Father which sent me, He gave me a commandment, what I should say, and what I should speak; and I know that His commandment is life everlasting: whatsoever I speak therefore, even as the Father said to me, so I speak. If therefore the Son judges not, but the word which the Son has spoken; and the word which the Son has spoken therefore judges, because the Son has not spoken of Himself, but the Father who sent Him gave Him a commandment what He should say, and what He should speak: then the Father assuredly judges, whose word it is which the Son has spoken; and the same Son Himself is the very Word of the Father. For the commandment of the Father is not one thing, and the word of the Father another; for He has called it both a word and a commandment. Let us see, therefore, whether perchance, when He says, I have not spoken of myself, He meant to be understood thus — I am not born of myself. For if He speaks the word of the Father, then He speaks Himself, because He is Himself the Word of the Father. For ordinarily He says, The Father gave to me; by which He means it to be understood that the Father begot Him: not that He gave anything to Him, already existing and not possessing it; but that the very meaning of, To have given that He might have, is, To have begotten that He might be. For it is not, as with the creature so with the Son of God before the incarnation and before He took upon Him our flesh, the Only-begotten by whom all things were made; that He is one thing, and has another: but He is in such way as to be what He has. And this is said more plainly, if any one is fit to receive it, in that place where He says: For as the Father has life in Himself, so has He given to the Son to have life in Himself. For He did not give to Him, already existing and not having life, that He should have life in Himself; inasmuch as, in that He is, He is life. Therefore He gave to the Son to have life in Himself means, He begot the Son to be unchangeable life, which is life eternal. Since, therefore, the Word of God is the Son of God, and the Son of God is the true God and eternal life, as John says in his Epistle; so here, what else are we to acknowledge when the Lord says, The word which I have spoken, the same shall judge him at the last day, and calls that very word the word of the Father and the commandment of the Father, and that very commandment everlasting life? And I know, He says, that His commandment is life everlasting.

27. I ask, therefore, how we are to understand, I will not judge him; but the Word which I have spoken shall judge him: which appears from what follows to be so said, as if He would say, I will not judge; but the Word of the Father will judge. But the Word of the Father is the Son of God Himself. Is it to be so understood: I will not judge, but I will judge? How can this be true, unless in this way: viz., I will not judge by human power, because I am the Son of man; but I will judge by the power of the Word, because I am the Son of God? Or if it still seems contradictory and inconsistent to say, I will not judge, but I will judge; what shall we say of that place where He says, My doctrine is not mine? How mine, when not mine? For He did not say, This doctrine is not mine, but My doctrine is not mine: that which He called His own, the same He called not His own. How can this be true, unless He has called it His own in one relation; not His own, in another? According to the form of God, His own; according to the form of a servant, not His own. For when He says, It is not mine, but His that sent me, He makes us recur to the Word itself. For the doctrine of the Father is the Word of the Father, which is the Only Son. And what, too, does that mean, He that believes in me, believes not on me? How believe in Him, yet not believe in Him? How can so opposite and inconsistent a thing be understood — Whoever believes in me, He says, believes not on me, but on Him that sent me;— unless you so understand it, Whoever believes in me believes not on that which he sees, lest our hope should be in the creature; but on Him who took the creature, whereby He might appear to human eyes, and so might cleanse our hearts by faith, to contemplate Himself as equal to the Father? So that in turning the attention of believers to the Father, and saying, Believes not on me, but on Him that sent me, He certainly did not mean Himself to be separated from the Father, that is, from Him that sent Him; but that men might so believe in Himself, as they believe in the Father, to whom He is equal. And this He says in express terms in another place, You believe in God, believe also in me: that is, in the same way as you believe in God, so also believe in me; because I and the Father are One God. As therefore, here, He has as it were withdrawn the faith of men from Himself, and transferred it to the Father, by saying, Believes not on me, but on Him that sent me, from whom nevertheless He certainly did not separate Himself; so also, when He says, It is not mine to give, but [it shall be given to them] for whom it is prepared by my Father, it is I think plain in what relation both are to be taken. For that other also is of the same kind, I will not judge; whereas He Himself shall judge the quick and dead. But because He will not do so by human power, therefore, reverting to the Godhead, He raises the hearts of men upwards; which to lift up, He Himself came down.
