Catena Aurea on John 3:32–36: John Chrysostom

Having said, And what he hath seen and heard, that he testifieth, to prevent any from supposing, that what he said was false, because only a few for the present believed, he adds, And no man receiveth his testimony; i. e. only a few; for he had disciples who received his testimony. John is alluding to the unbelief of his own disciples, and to the insensibility of the Jews, of whom we read in the beginning of the Gospel, He came unto His own, and His own received Him not.
