Catena Aurea on John 5:31–40: John Chrysostom

But according to the former interpretation, they might say to Him, If Thy witness is not true, how sayest Thou, I know that the witness of John is true? But His answer meets the objection: Ye sent unto John, and he bare witness of the truth: as if to say: Ye would not have sent to John, if ye had not thought him worthy of credit. And what is more remarkable, they did send to him, not to ask Him about Christ, but about himself. For they who were sent out did not say, What sayest thou of Christ? but, Who art thou? what sayest thou of thyself? (c. 1:22) In so great admiration did they hold him.
