Tractates on the Gospel of John

⁷ 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 Your doctrine is not Yours, O Lord, whose is it, unless there be another whose it is? The Sabellians understand not what You said; 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.

8. “He that speaks of himself seeks his own glory: 'This will be he who is called Antichrist,' exalting himself,” as the apostle says, “above all that is called God, and that is worshipped.” The Lord, declaring that this same it is that will seek his own glory, not the glory of the Father, says to the Jews: “I have come in my Father's name, and you have not received me; another will come in his own name, him you will receive.” He intimated that they would receive Antichrist, who will seek the glory of his own name, puffed up, not solid; and therefore not stable, but assuredly ruinous. But our Lord Jesus Christ has shown us a great example of humility: for doubtless He is equal with the Father, for “in the beginning was the Word, and the Word was with God, and the Word was God;” yea, doubtless, He Himself said, and most truly said, “Am I so long time with you, and you have not known me, Philip? He that has seen me has seen the Father.” Yea, doubtless, Himself said, and most truly said, “I and the Father are one.” If, therefore, He is one with the Father, equal to the Father, God from God, God with God, coeternal, immortal, alike unchangeable, alike without time, alike Creator and disposer of times; and yet because He came in time, and took the form of a servant, and in condition was found as a man, He seeks the glory of the Father, not His own; what ought thou to do, O man, who, when you do anything good, seekest your own glory; but when you do anything ill, dost meditate calumny against God? Consider yourself: you are a creature, acknowledge your Creator: you are a servant, despise not your Lord: you are adopted, not for your own merits; seek His glory from whom you have this grace, that you are a man adopted; His, whose glory He sought who is from Him, the Only-begotten. “But He that seeks His glory that sent Him, the same is true, and no unrighteousness is in Him.” In Antichrist, however, there is unrighteousness, and he is not true; because he will seek his own glory, not His by whom he was sent: for, indeed, he was not sent, but only permitted to come. Let us all, therefore, that belong to the body of Christ, seek not our own glory, that we be not led into the snares of Antichrist. But if Christ sought His glory that sent Him, how much more ought we to seek the glory of Him who made us?
