Tractates on John 29
How then did the Lord answer those that were marvelling how He knew letters which He had not learned? "My doctrine," saith He, "is not mine, but His that sent me." This is the first profundity. For He seems as if in a few words He had spoken contraries. For He says not, This doctrine is not mine; but, "My doctrine is not mine." If not Thine, how Thine? If Thine, how not Thine? For Thou sayest both: both, "my doctrine;" and, "not mine." For if He had said, This doctrine is not mine, there would have been no question. But now, brethren, in the first place, consider well the question, and so in due order expect the solution. For he who sees not the question proposed, how can he understand what is expounded? The subject of inquiry, then, is that which He says, "My, not mine" this appears to be contrary; how "my," how "not mine"? If we carefully look at what the holy evangelist himself says in the beginning of his Gospel, "In the beginning was the Word, and the Word was with God, and the Word was God;" thence hangs the solution of this question. What then is the doctrine of the Father, but the Father's Word? Therefore, Christ Himself is the doctrine of the Father, if He is the Word of the Father. But since the Word cannot be of none, but of some one, He said both "His doctrine," namely, Himself, and also, "not His own," because He is the Word of the Father. For what is so much "Thine" as Thyself? And what so much not Thine as Thyself, if that Thou art is of another?
The Word then is God; and it is also the Word of a stable, unchangeable doctrine, not such as can be sounded by syllables and fleeting, but abiding with the Father, to which abiding doctrine let us be converted, being admonished by the transitory sounds of the voice. For that which is transitory does not so admonish us as to call us to transitory things. We are admonished to love God. All this that I have said were syllables; they smote through the air to reach your sense of hearing, and by sounding passed away: that, however, which I advise you ought not so to pass away, because He whom I exhort you to love passes not away; and when you, exhorted in transient syllables, shall have been converted, you shall not pass away, but shall abide with Him who is abiding. There is therefore in the doctrine this great matter, this deep and eternal thing which is permanent: whither all things that pass away in time call us, when they mean well and are not falsely put forward. For, in fact, all the signs which we produce by sounds do signify something which is not sound. For God is not the two short syllables "Deus," and it is not the two short syllables that we worship, and it is not the two short syllables that we adore, nor is it to the two short syllables that we desire to come-two syllables which almost cease to sound before they have begun to sound; nor in sounding them is there room for the second until the first has passed away. There remains, then, something great which is called "God," although the sound does not remain when we say the word "God." Thus direct your thoughts to the doctrine of Christ, and ye shall arrive at the Word of God; and when you have arrived at the Word of God, consider this, "The Word was God," and you will see that it was said truly, "my doctrine:" consider also whose the Word is, and you will see that it was rightly said, "is not mine."
Therefore, to speak briefly, beloved, it seems to me that the Lord Jesus Christ said, "My doctrine is not mine," meaning the same thing as if He said, "I am not from myself." For although we say and believe that the Son is equal to the Father, and that there is not any diversity of nature and substance in them, that there has not intervened any interval of time between Him that begets and Him that is begotten, nevertheless we say these things, while keeping and guarding this, that the one is the Father, the other the Son. But Father He is not if He have not a Son, and Son He is not if He have not a Father: but yet the Son is God from the Father; and the Father is God, but not from the Son. The Father of the Son, not God from the Son: but the other is Son of the Father, and God from the Father. For the Lord Christ is called Light from Light. The Light then which is not from Light, and the equal Light which is not from Light, are together one Light not two Lights.
If we have understood this, thanks be to God; but if any has not sufficiently understood, man has done as far as he could: as for the rest, let him see whence he may hope to understand. As laborers outside, we can plant and water; but it is of God to give the increase. "My doctrine," saith He, "is not mine, but His that sent me." Let him who says he has not yet understood hear counsel. For since it was a great and profound matter that had been spoken, the Lord Christ Himself did certainly see that all would not understand this so profound a matter, and He gave counsel in the sequel. Dost thou wish to understand? Believe. For God has said by the prophet: "Except ye believe, ye shall not understand." To the same purpose what the Lord here also added as He went on "If any man is willing to do His will, he shall know concerning the doctrine, whether it be of God, or whether I speak from myself." What is the meaning of this, "If any man be willing to do His will"? But I had said, if any man believe; and I gave this counsel: If thou hast not understood, said I, believe. For understanding is the reward of faith. Therefore do not seek to understand in order to believe, but believe that thou mayest understand; since, "except ye believe, ye shall not understand." Therefore when I would counsel the obedience of believing toward the possibility of understanding, and say that our Lord Jesus Christ has added this very thing in the following sentence, we find Him to have said, "If any man be willing to do His will, he shall know of the doctrine." What is "he shall know"? It is the same thing as "he shall understand." But what is "If any man be willing to do His will"? It is the same thing as to believe. All men indeed perceive that "shall know" is the same thing as "shall understand:" but that the saying, "If any man be willing to do His will," refers to believing, all do not perceive; to perceive this more accurately, we need the Lord Himself for expounder, to show us whether the doing of the Father's will does in reality refer to believing. But who does not know that this is to do the will of God, to work the work of God; that is, to work that work which is pleasing to Him? But the Lord Himself says openly in another place: "This is the work of God, that ye believe on Him whom He has sent." "That ye believe on Him," not, that ye believe Him. But if ye believe on Him, ye believe Him; yet he that believes Him does not necessarily believe on Him. For even the devils believed Him, but they did not believe on Him. Again, moreover, of His apostles we can say, we believe Paul; but not, we believe on Paul: we believe Peter; but not, we believe on Peter. For, "to him that believeth on Him that justifieth the ungodly, his faith is counted unto him for righteousness." What then is "to believe on Him"? By believing to love Him, by believing to esteem highly, by believing to go into Him and to be incorporated in His members. It is faith itself then that God exacts from us: and He finds not that which He exacts, unless He has bestowed what He may find. What faith, but that which the apostle has most amply defined in another place, saying, "Neither circumcision availeth anything, nor uncircumcision, but faith that worketh by love?" Not any faith of what kind soever, but "faith that worketh by love:" let this faith be in thee, and thou shalt understand concerning the doctrine. What indeed shalt thou understand? That "this doctrine is not mine, but His that sent me;" that is, thou shalt understand that Christ the Son of God, who is the doctrine of the Father, is not from Himself, but is the Son of the Father.
This sentence overthrows the Sabellian heresy. The Sabellians have dared to affirm that the Son is the very same as He who is also the Father: that the names are two, but the reality one. If the names were two and reality one, it would not be said, "My doctrine is not mine." Anyhow, if Thy doctrine is not Thine, O Lord, whose is it, unless there be another whose it is? The Sabellians understand not what Thou saidst; for they see not the trinity, but follow the error of their own heart. Let us worshippers of the trinity and unity of Father, Son, and Holy Ghost, and one God, understand concerning Christ's doctrine, how it is not His. And He said that He spoke not from Himself for this reason, because Christ is the Son of the Father, and the Father is the Father of Christ; and the Son is from God the Father, God, but God the Father is God not from God the Son.

Catena Aurea by Aquinas
(Tract. xxix. s. 3) Mine is not mine, appears a contradiction; why did He not say, This doctrine is not Mine? Because the doctrine of the Father being the Word of the Father, and Christ Himself being that Word, Christ Himself is the doctrine of the Father. And therefore He calls the doctrine both His own, and the Father's. A word must be a word of some one's. What is so much Thine as Thou, and what is so much not Thine as Thou, if what Thou art, Thou art of another. His saying then, My doctrine is not Mine own, seems briefly to express the truth, that He is not from Himself; it refutes the Sabellian heresy, which dares to assert that the Son is the same as the Father, there being only two names for one thing.
(de Trin. i. c. xi) Or thus: In one sense He calls it His, in another sense not His; according to the form of the Godhead His, according to the form of the servant not His.
(Tract. xxix. s. 6) Should any one however not understand this, let him hear the advice which immediately follows from our Lord: If any man will do His will, he shall know of the doctrine, whether it be of God, or whether I speak of Myself. What meaneth this, If any man will do His will? To do His will is to believe on Him, as He Himself says, This is the work of God, that ye believe on Him whom He hath sent. (c. 6:29) And who does not know, that to work the work of God, is to do His will? To know is to understand. Do not then seek to understand in order to believe, but believe in order to understand, for, Except ye believe, ye shall not understand. (Is. 7:9. Vulg.)

Commentary on the Gospel of John, Book 4
We ought uncritically and without all doubt to receive the words of the Truth, and to believe that a thing once said, cannot be otherwise than as it was declared to be. But He permits not His saying to be without proof, on account of the unbelievers, but introduces a most evident and exceeding clear solution, tempering with much skill the fashion of His words. And what the skill is, what the order of the economy, we will again say. They were seeking to kill Him on account of the paralytic, him (I mean) that was healed on the sabbath day. Gently then does He alike scare them from their dreadful purpose against Him, and clearly does He convict those who are travailing with their blood-thirsty purpose against Him, that they were choosing to fulfil their own lust rather than the will of the Law-giver. For then (saith He) shall ye know perfectly of My doctrine, that it is of God the Father, when ye shall choose to follow His Will rather than your own. But the Will of the Law-giver and of God, is to abstain wholly from murder. Then, then (He saith) shall ye, not holden beforehand by unjust hatred, nor thrust forth in brutish guise to no seasonable anger, know clearly, whether the word of My teaching is of God, or whether I am speaking of Myself. Having therefore interwoven reproof with profit, He with justice accuses them, for that they unreasonably mock at what He teaches, though God the Father consenteth and co-willeth, or what also is true, co-teacheth and co-interpreteth. But He puts Of Myself, for, Privately and wholly severed from being after the Co-Will and Purpose of the Father. And I do not suppose any person of sound mind will think that He accuses His own words of being spurious, but says that they will never be otherwise than in accordance with the Will of God the Father. For He speaks by His own Word and Wisdom, His Own Offspring; but That speaks not at all diversely from Himself, for how could It?
