John Chrysostom
Catena Aurea · Johannesevangelium 7
Now about the midst of the feast Jesus went up into the temple, and taught. And the Jews marvelled, saying, How knoweth this man letters, having never learned? Jesus answered them, and said, My doctrine is not mine, but his that sent me. If any man will do his will, he shall know of the doctrine, whether it be of God, or whether I speak of myself. He that speaketh of himself seeketh his own glory: but he that seeketh his glory that sent him, the same is true, and no unrighteousness is in him.
(Hom. xlix. 2) Or He calls it His own, inasmuch as He taught it; not His own, inasmuch as the doctrine was of the Father. If all things however which the Father hath are His, the doctrine for this very reason is His; i. e. because it is the Father’s. Rather that He says, Is not Mine own, shews very strongly, that His doctrine and the Father’s are one: as if He said, I differ nothing from Him; but so act, that it may be thought I say and do nothing else than doth the Father.
