He that comes from above is above all: he that is of the earth is earthly, and speaks of the earth: he that comes from heaven is above all.
All Commentaries on John 3:31 Go To John 3
John Chrysostom
AD 407
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 itin his disciples: for after what he has said above, he said yet again, He that comes from above is above all: meaning, You 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 comes from heaven, cannot be accredited by an earthly witness. He is above all; being perfect in Himself, and above comparison.
And yet he was not altogether of the earth; for he had a soul, and partook ofa spirit, which was not of the earth. What means he then by saying that he is of the earth? Only to express his own worthlessness, that he is one born on the earth, creeping on the ground, and not to be compared with Christ, Who comes from above. Speaks of the earth, does not mean that he spoke from his own understanding; but that, in comparison with Christ's doctrine, he spoke of the earth: as if he said, My doctrine is mean and humble, compared with Christ’s; as becomes an earthly teacher, compared with Him, in Whom are hid all the treasures of wisdom and knowledge.
Having corrected the bad feeling of his disciples, he comes to discourse more deeply upon Christ. Before this it would have been useless to reveal the truths which could not yet gain a place in their minds. It follows therefore, He that comes from heaven.
But after this, high and solemn mention of Christ, his tone lowers: And what he has seen and heard, that he testifies. As our senses are our surest channels of knowledge, and teachers are most depended on who have apprehended by sight or hearing what they teach, John adds this argument in favor of Christ, that, what he has seen and heard, that he testifies: meaning that every thing which He said is true. I want, said John, to hear what things He, Who comes from above, has seen and heard, i.e. what He, and He alone, knows with certainty.
