John Chrysostom — as excerpted in the Catena Aurea on Matthew 11:16-19

“He says therefore, Jesus came, as much as to say, I and John came opposite ways, to do the same thing; as two hunters chasing the same animal from opposite sides, so that it might fall into the hands of one of them. But all mankind admire fasting and severity of life; and for this reason it was ordained from his infancy that John should be so brought up, that the things that he should say should receive credit. The Lord also walked in this way when He fasted forty days; but He had other means of teaching men to have confidence in Him; for it was a much greater thing that John who had walked in this way should bear witness to Him, than that He Himself should walk in that way. Again, John had nothing to shew besides his life, and his righteousness; whereas Christ had also the witness of His miracles. Leaving therefore to John the representation of fasting, He Himself walked in a contrary way, entering to the table of the publicans, and eating and drinking with them.”
