23. It was for this reason that his parents said: "He is old enough. Ask him."
24. Therefore, they again called the man who had been blind, and they said to him: "Give glory to God. We know that this man is a sinner."
25. And so he said to them: "If he is a sinner, I do not know it. One thing I do know, that although I was blind, now I see."
26. Then they said to him: "What did he do to you? How did he open your eyes?"
27. He answered them: "I have already told you, and you heard it. Why do you want to hear it again? Do you also want to become his disciples?"
28. Therefore, they cursed him and said: "You be his disciple. But we are disciples of Moses.
29. We know that God spoke to Moses. But this man, we do not know where he is from."
30. The man responded and said to them: "Now in this is a wonder: that you do not know where he is from, and yet he has opened my eyes.
31. And we know that God does not hear sinners. But if anyone is a worshipper of God and does his will, then he heeds him.
32. From ancient times, it has not been heard that anyone has opened the eyes of someone born blind.
33. Unless this man were of God, he would not be able to do any such thing."
