John 5:19,20

Ver 19. Then answered Jesus and said to them, Verily, verily, I say to you, The Son can do nothing of himself, but what he sees the Father do: for what things soever he does, these also does the Son likewise. 20. For the Father loves the Son, and shows him all things that himself does: and he will show him greater works than these, that you may marvel.

HILARY. He refers to the charge of violating the sabbath, brought against Him. My Father works hitherto, and I work; meaning that He had a precedent for claiming the right He did; and that what He did was in reality His Father's doing, who acted in the Son. And to quiet the jealousy which had been raised, because by the use of His Father's name He had made Himself equal with God, and to assert the excellency of His birth and nature, He says, Verily, verily, I say to you, The Son can do nothing of Himself, but what He sees the Father do.

AUG. Some who would be thought Christians, the Arian heretics, who say that the very Son of God who took our flesh upon Him, was inferior to the Father, take advantage of these words to throw discredit upon our doctrine, and say, You see that when our Lord perceived the Jews to be indignant, because He seemed to make Himself equal with God, He gave such an answer as showed that He was not equal. For they say, he who can do nothing but what he sees the Father do is not equal but inferior to the Father. But if there is a greater God, and a less God, (the Word being God,) we worship two Gods, and not one.

HILARY. Lest then that assertion of His equality, which must belong to Him, as by Name and Nature the Son, might throw doubt upon His Nativity, He says that the Son can do nothing of Himself.

AUG. As if He said: Why are you offended that I called God My Father, and that I make Myself equal with God? I am equal, but equal in such a sense as is consistent with His having begotten Me; with My being from Him, not Him from Me. With the Son, being and power are one and the same thing. The Substance of the Son then being of the Father, the power of the Son is of tile Father also: and as the Son is not of Himself, so He can not of Himself. The Son can do nothing of Himself, but what He sees the Father do. His seeing and His being born of the Father are the same. His vision is not distinct from His Substance, but the whole together is of the Father.

HILARY. That the wholesome order of our confession, i.e. that we believe in the Father and the Son, might remain, He shows the nature of His birth; viz. that He derived the power of acting not from au accessible of strength supplied for each work, but by His own knowledge in the first instance. And this knowledge He derived not from any particular visible precedents, as if what the Father had done, the Son could do afterwards; but that the Son being born of the Father, and consequently conscious of the Father's virtue and nature within Him, could do nothing but what He saw the Father do: as he here testifies; God does not see by bodily organs, but by the virtue of His nature. AUG. If we understand this subordination of the Son to arise from the human nature, it will follow that the Father walked first upon the water, and did all the other things which the Son did in the flesh, in order that the Son might do them. Who can be so insane as to think this?

AUG. Yet that walking of the flesh upon the sea was done by the Father through the Son. For when the flesh walked, and the Divinity of the Son guided, the Father was not absent, as the Son Himself said below, The Father that dwells in Me, He does the works. He guards however against the carnal. interpretation of the words, The Son can do nothing of Himself. As if the case were like that of two artificers, master and disciple, one of whom made a chest, and the other made another like it, by adding, For whatsoever things he does, these do the Son likewise. He does not say, Whatsoever the Father does, the Son does other things like them, but the very same things. The Father made the world, the Son made the world, the Holy Ghost made the world. If the Father, Son, and Holy Ghost are one, it follows that one and the same world was made by the Father, through the Son, in the Holy Ghost. Thus it is the very same thing that the Son does. He adds likewise, to prevent another error arising. For the body seems to do the same things with the mind, but it does not do them in a like way, inasmuch as the body is subject, the soul governing, the body visible, the soul invisible. When a slave does a thing at the command of his master, the same thing is done by both; but is it in a like way? Now in the Father and Son there is not this difference; they do the same things, and in a like way. Father and Son act with the same power; so that the Son is equal to the Father.

HILARY. Or thus; All things and the same, He says, to show the virtue of His nature, its being the same with God's. That is the same nature, which can do all the same things. And as the Son does all the same things in a like way, the likeness of the works excludes the notion of the worker existing alone g. Thus we come to a true idea of the Nativity, as our faith receives it: the likeness of the works bearing witness to the Nativity, their sameness to the Nature.

CHRYS. Or thus; That the Son can do nothing of Himself, must be understood to mean, that He can do nothing contrary to, or displeasing to, the Father. And therefore He does not say that He does nothing contrary, but that He can do nothing; in order to show His perfect likeness, and absolute equality to the Father. Nor is this a sign of weakness in the Son, but rather of goodness. For as when we say that it is impossible for God to sin, we do not charge Him with weakness, but bear witness to a certain ineffable goodness; so when the Son says, I can do nothing of myself, it only means, that He can do nothing contrary to the Father.

AUG. This is not a sign of failing in Him, but of His abiding in His birth from the Father. And it is as high an attribute of the Almighty that He does not change, as it is that Ho does not die. The Son could do what He had not seen the Father doing, if He could do what the Father does not do through Him; i.e. if He could sin: a supposition inconsistent with the immutably good nature which was begotten from the Father. That He cannot do; this then is to be understood of Him, not in the sense of deficiency, but of power.

CHRYS. And this is confirmed by what follows: For whatsoever be does these also do the Son likewise. For it the Father does all things by Himself, so does the Son also, if this likewise is to stand good. You see how high a meaning these humble words bear. He gives His thoughts a humble dress purposely. For whenever He expressed Himself loftily, He was persecuted, as an enemy of God. AUG. Having said that He did the same A things that the Father did, and in a like way, He adds, For the Father loves the Son, and shows Him all things that Himself does. And shows Him all things that Himself does: this has a reference to the words above; But what He sees the Father do. But again, our human ideas are perplexed, and one may say, So then the Father first does something, that the Son may see what He does; just as an artificer teaches his son his art, and shows him what he makes, that he may be able to make the same after him. On this supposition, when the Father does a thing, the Son does not do it; in that the Son is beholding what His Father does. But we hold it as a fixed and incontrovertible truth, that the Father makes all things through the Son, and therefore He must show them to the Son, before He makes them. And where does the Father show the Son what He makes, except in the Son I Himself, by whom He makes them? For if the Father makes a thing for a pattern, and the Son attends to the workmanship as it goes on, where is the indivisibility of the Trinity? The Father therefore does not show the Son what He does by doing it, but by showing does it, through the Son. The Son sees, and the Father shows, before a thing is made, and from the showing of the Father, and the seeing of the Son, that is made which is made; made by the Father, through the Son. But you will say, I show my Son what I wish him to make, and he makes it, and I make it through him. True; but before you do any thing, you show it to your son, that he may do it for your example, and you by him; but you speak to your son words which are not yourself; whereas the Son Himself is the Word of the Father; and could He speak by the Word to the Word? Or, because the Son was the great Word, were lesser words to pass between the Father and the Son, or a certain sound and temporary creation, as it were, to go out of the mouth of the Father, and strike the ear of the Son? Put away these bodily notions, and if you are simple, see the truth in simplicity. If you can not comprehend what God is, comprehend at least what He is not. You will have advanced no little way, if you think nothing that is untrue of God. See what I am saying exemplified in your own mind. You have memory, and thought, your memory shows to your thought Carthage: before you perceive what is in her, she shows it to thought, which is turned toward her: the memory then has shown, the thought has perceived, and no words have passed between them, no outward sign been used. But whatever is in your memory, you receive from without: that which the Father shows to the Son, He does not receive from without; the whole goes on within; there being no creature existing without, but what the Father has made by the Son. And the Father makes by showing, in that He makes by, the Son who sees. The Father's showing begets the Son's seeing, as the Father begets the Son? Showing begets seeing, not seeing showing. But it would be more correct, and more spiritual, not to view the Father as distinct from His showing, or the Son from His seeing.

HILARY. It must not be supposed that the Only Begotten God needed such showing on account of ignorance. For the showing here is only the doctrine of the nativity; the self-existing Son, from the self-existing Father.

AUG. For to see the Father is to see His Son. The Father so shows all His works to the Son, that the Son sees them from the Father. For the birth of the Son is in His seeing: He sees from the same source, from which He is, and is born, and remains.

HILARY. Nor did the heavenly discourse lack the caution, to guard against our inferring from these words any difference in the nature of the Son and the Father. For He says that the works of the Father were shown to Him, not that strength was supplied Him for the doing of them, in order to teach that this showing is substantially nothing else than His birth; for that simultaneously with the Son Himself is born the Son's knowledge of the works the Father will do through Him.

AUG. But now from Him whom we called co-eternal with the Father, who saw the Father' and existed in that He saw, we return to the things of time, And He will show him greater works than these. But if He will show him, i.e. is about to show him, He has not yet shown him: and when He does show him, others also will see; for it follows, That you may believe. It is difficult to see what the eternal Father can show in time to the co-eternal Son, Who knows all that exists within the Father's mind. For as the Father raises up the dead and quickens them even so the Son quickens whom He will. To raise the dead was a greater work than to heal the sick. But this is explained by considering that He Who a little before spoke as God, now begins to speak as man. As man, and therefore living in time, He will be strewn greater works in time. Bodies will rise again by the human dispensation by which the Son of God assumed manhood in time; but souls by virtue of the eternity of the Divine Substance. For which reason it was said before that the Father loved the Son, and showed Him what things soever He did. For the Father shows the Son that souls are raised up; for they are raised up by the Father and the Son, even as they cannot live, except God give them life. Or the Father is about to show this to us, not to Him; according to what follows, That you may believe. This being the reason why the Father would show Him greater things than these. But why did He not say, shall show you, instead of the Son? Because we are members of the Son, and He, as it were, learns in His members, even as He suffers in us. For as He says, Inasmuch as you have done it to one of the least of these My brethren, you have done it to Me: so if we ask Him, how He, the Teacher of all things, learns, He replies, When one of the least of My brethren learns, I learn.
