John Chrysostom
Catena Aurea · Johannesevangelium 3
He that cometh from above is above all: he that is of the earth is earthly, and speaketh of the earth: he that cometh from heaven is above all. And what he hath seen and heard, that he testifieth;
(Hom. xxx. 1) As the worm gnaws wood, and rusts iron, so vainglory destroys the soul that cherishes it. But it is a most obstinate fault. John with all his arguments can hardly subdue it in his disciples: for after what he has said above, he saith yet again, He that cometh from above is above all: meaning, Ye extol my testimony, and say that the witness is more worthy to be believed, than He to whom he bears witness. Know this, that He who cometh from heaven, cannot be accredited by an earthly witness. He is above all; being perfect in Himself, and above comparison.
