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?
