Catena Aurea on Luke 7:18–23: Cyril of Alexandria

Or he asks the question by economy. For as the forerunner he knew the mystery of Christ’s passion, but that his disciples might be convinced how great was the excellence of the Saviour, he sent the more understanding of them, instructing them to enquire and learn from the very words of the Saviour, whether it was He who was expected; as it is added, But when the men were come unto him, they said, John the Baptist hath sent us unto thee, saying, Art thou He, &c. But He knowing as God with what intention John had sent them, and the cause of their coming, was at the time performing many miracles, as it follows, And in the same hour he healed many of their infirmities, &c. He said not positively to them I am he, but rather leads them to the certainty of the fact, in order that receiving their faith in Him, with their reason agreeing thereto, they might return to him who sent them. Hence He made not answer to the words, but to the intention of him who sent them; as it follows, And Jesus answering said unto them, Go your way, and tell John what things you have seen and heard: as if He said, Go and tell John the things which ye have heard indeed through the Prophets, but have seen accomplished by Me. For He was then performing those things which the Prophets prophesied He would do; that is of which it is added, For the blind see, the lame walk.
