John Chrysostom
Catena Aurea · Matthäusevangelium 11
And it came to pass, when Jesus had made an end of commanding his twelve disciples, he departed thence to teach and to preach in their cities. Now when John had heard in the prison the works of Christ, he sent two of his disciples, And said unto him, Art thou he that should come, or do we look for another? Jesus answered and said unto them, Go and shew John again those things which ye do hear and see: The blind receive their sight, and the lame walk, the lepers are cleansed, and the deaf hear, the dead are raised up, and the poor have the Gospel preached to them. And blessed is he, whosoever shall not he offended in me.
So also Christ as knowing the mind of John, said not, I am He; for thus He would have put an obstacle in the way of those that heard Him, who would have at least thought within themselves, if they did not say, what the Jews did say to Christ, Thou bearest witness of thyself. (John 8:13.) Therefore He would have them learn from His miracles, and so presented His doctrine to them more clear, and without suspicion. For the testimony of deeds is stronger than the testimony of words. Therefore He straightway healed a number of blind, and lame, and many other, for the sake not of John who had knowledge, but of others who doubted; as it follows, And Jesus answered and said unto them, Go and tell John what ye have heard and scen; The blind see, the lame walk, the lepers are cleansed, the deaf hear, the dead are raised, the poor have the Gospel preached to them.
