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.
(in Luc. 7. 19.) Some understand it thus; That it was a great thing that John should be so far a prophet, as to acknowledge Christ, and to preach remission of sin; but that like a pious prophet, he could not think that He whom he had believed to be He that should come, was to suffer death; he doubted therefore though not in faith, yet in love. So Peter also doubted, saying, This be far from thee, Lord; this shall not be unto thee. (Mat. 16:22.)
