Tractates on the Gospel of John

¹⁶ Further, what said the evangelist as he went on? “Therefore the Jews sought the more to kill Him, because He not only broke the Sabbath, but said also that God was His Father;” not in any ordinary manner, but how? “Making Himself equal with God.” For we all say to God, “Our Father which art in heaven;” we read also that the Jews said, “Seeing You are our Father.” Therefore it was not for this they were angry, because He said that God was His Father, but because He said it in quite another way than men do.

Behold, the Jews understand what the Arians do not understand. The Arians, in fact, say that the Son is not equal with the Father, and hence it is that the heresy was driven from the Church. Lo, the very blind, the very slayers of Christ, still understood the words of Christ. They did not understand Him to be Christ, nor did they understand Him to be the Son of God: but they did nevertheless understand that in these words such a Son of God was intimated to them as should be equal with God.

Who He was they knew not; still they did acknowledge such a One to be declared, in that “He said God was His Father, making Himself equal with God.” Was He not therefore equal with God? He did not make Himself equal, but the Father begot Him equal. Were He to make Himself equal, He would fall by robbery. For he who wished to make himself equal with God, while he was not so, fell, and of an angel became a devil, and administered to man that cup of pride by which himself was cast down.

For this fallen said to man, envying his standing, “Taste, and you shall be as gods;” that is, seize to yourselves by usurpation that which you are not made, for I also have been cast down by robbery. He did not put forth this, but this is what he persuaded to. Christ, however, was begotten equal to the Father, not made; begotten of the substance of the Father. Whence the apostle thus declares Him: “Who, being in the form of God, thought it not robbery to be equal with God.” What means “thought it not robbery”?

He usurped not equality with God, but was in that equality in which He was begotten. And how were we to come to the equal God? “He emptied Himself, taking upon Him the form of a servant.” But He emptied Himself not by losing what He was, but by taking to Him what He was not. The Jews, despising this form of a servant, could not understand the Lord Christ equal to the Father, although they had not the least doubt that He affirmed this of Himself, and therefore were they enraged: and yet He still bore with them, and sought the healing of them, while they raged against Him.
