John Chrysostom
Catena Aurea · Johannesevangelium 9
Jesus heard that they had cast him out; and when he had found him, he said unto him, Dost thou believe on the Son of God? He answered and said, Who is he, Lord, that I might believe on him? And Jesus said unto him, Thou hast both seen him, and it is he that talketh with thee. And he said, Lord, I believe. And he worshipped him. And Jesus said, For judgment I am come into this world, that they which see not might see; and that they which see might be made blind. And some of the Pharisees which were with him heard these words, and said unto him, Are we blind also? Jesus said unto them, If ye were blind, ye should have no sin: but now ye say, We see: therefore your sin remaineth.
(Hom. lix. 1) But the blind man did not yet know Christ, for before he went to Christ he was blind, and after his cure, he was taken hold of by the Jews: He answered and said, Who is He, Lord, that I might believe on Him? The speech this of a longing and enquiring mind. He knows not who He is for whom he had contended so much; a proof to thee of his love of truth. The Lord however says not to him, I am He who healed thee; but uses a middle way of speaking, Thou hast both seen Him.
