Augustine of Hippo
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.
(Tract. xxix. s. 8) He who seeketh his own glory is Antichrist. But our Lord set us an example of humility, in that being found in fashion as a man, He sought His Father’s glory, not His own. Thou, when thou doest good, takest glory to thyself, when thou doest evil, upbraidest God.
