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 these things which were done concerning John, there is a deep store of mystic meaning. The very condition and circumstances of a prophet are themselves a prophecy. John signifies the Law; for the Law proclaimed Christ, preaching remission of sins, and giving promise of the kingdom of heaven. Also when the Law was on the point of expiring, (having been, through the sins of the people, which hindered them from understanding what it spake of Christ, as it were shut up in bonds and in prison,) it sends men to the contemplation of the Gospel, that unbelief might see the truth of its words established by deeds.
