2 Now when John had heard in prison the works of Christ: sending two of his disciples he said to him: 3 Art thou he that art to come, or look we for another?
Jerome: He does not ask as being himself ignorant. But as the Saviour asks where Lazarus is buried, in order that they who shewed Him the sepulchre might be so far prepared for faith, and believe that the dead was verily raised again — so John, about to be put to death by Herod, sends his disciples to Christ, that by this opportunity of seeing His signs and wonders they might believe on Him, and so might learn through their master’s enquiry.
Chrysostom: 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.
4 And Jesus making answer said to them: Go and relate to John what you have heard and seen. 5 The blind see, the lame walk, the lepers are cleansed, the deaf hear, the dead rise again, the poor have the gospel preached to them.
Chrysostom: 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.
6 And blessed is he that shall not be scandalized in me.
Gregory: The mind of unbelievers was greatly offended concerning Christ, because after many miracles done, they saw Him at length put to death; whence Paul speaks, “We preach Christ crucified, to the Jews a stumbling-block.” [1 Cor 1:23]
