Theophylact of Ohrid
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.
Or, if ye were blind, i. e. ignorant of the Scriptures, your offence would be by no means so heavy a one, as erring out of ignorance: but now, seeing ye call yourselves wise and understanding in the law, your own selves condemn you.
