John 9:35-41

35 Jesus heard that they had cast him out. And when he had found him, he said to him: Dost thou believe in the Son of God?

36 He answered, and said: Who is he, Lord, that I may believe in him?

37 And Jesus said to him: Thou hast both seen him; and it is he that talketh with thee.

38 And he said: I believe, Lord. And falling down, he adored him.

39 And Jesus said: For judgment I am come into this world: that they who see not may see; and they who see may become blind.

40 And some of the Pharisees, who were with him, heard: and they said unto him: Are we also blind?

41 Jesus said to them: If you were blind, you should not have sin: but now you say: We see. Your sin remaineth.
