17 For the law was given through Moses; grace and the true way of life are ours through Jesus Christ.
18 No man has seen God at any time; the only Son, who is on the breast of the Father, he has made clear what God is.
19 And this is the witness of John when the Jews sent priests and Levites from Jerusalem to him with the question, Who are you?
20 He said quite openly and straightforwardly, I am not the Christ.
21 And they said to him, What then? Are you Elijah? And he said, I am not. Are you the prophet? And his answer was, I am not.
22 So they said to him, Who are you then? We have to give some answer to those who sent us. What have you to say about yourself?
23 He said, I am the voice of one crying in the waste land, Make straight the way of the Lord, as said Isaiah the prophet.
