John Chrysostom — as excerpted in the Catena Aurea on Matthew 11:1-6

“Yet whilst John was with them he held them rightly convinced concerning Christ. But when he was going to die, he was more concerned on their behalf. For he feared that he might leave his disciples a prey to some pernicious doctrine, and that they should remain separate from Christ, to whom it had been his care to bring all his followers from the beginning. Had he said to them, Depart from me, for He is better than me, he would not have prevailed with them, as they would have supposed that he spoke this in humility, which opinion would have drawn them more closely to him. What then does he? He waits to hear through them that Christ works miracles. Nor did he send all, but two only, (whom perhaps he chose as more ready to believe than the rest,) that the reason of his enquiry might be unsuspected, and that from the things themselves which they should see they might understand the difference between him and Jesus.”
