John Chrysostom — as excerpted in the Catena Aurea on John 10:14-21

“(Hom. lx. 3) Because He spoke as one greater than man, they said He had a devil. But that He had not a devil, others proved from His works: Others said, These are not the words of Him that hath a devil. Can a devil open the eyes of the blind? As if to say, Not even the words themselves are those of one that hath a devil; but if the words do not convince you, be persuaded by the works. Our Lord having already given proof who He was by His works, was silent. They were unworthy of an answer. Indeed, as they disagreed amongst themselves, an answer was unnecessary. Their opposition only brought out, for our imitation, our Lord’s gentleness, and long suffering.”
