John 1:7-9, 15, 17, 19-27

He came as a witness to testify concerning that light, so that through him all might believe. He himself was not the light; he came only as a witness to the light. The true light that gives light to everyone was coming into the world.

(John testified concerning him. He cried out, saying, “This is the one I spoke about when I said, ‘He who comes after me has surpassed me because he was before me.’ ”)

For the law was given through Moses; grace and truth came through Jesus Christ.

Now this was John’s testimony when the Jewish leaders in Jerusalem sent priests and Levites to ask him who he was. He did not fail to confess, but confessed freely, “I am not the Messiah.” They asked him, “Then who are you? Are you Elijah?” He said, “I am not.” “Are you the Prophet?” He answered, “No.” Finally they said, “Who are you? Give us an answer to take back to those who sent us. What do you say about yourself?” John replied in the words of Isaiah the prophet, “I am the voice of one calling in the wilderness, ‘Make straight the way for the Lord.’ ” Now the Pharisees who had been sent questioned him, “Why then do you baptize if you are not the Messiah, nor Elijah, nor the Prophet?” “I baptize with water,” John replied, “but among you stands one you do not know. He is the one who comes after me, the straps of whose sandals I am not worthy to untie.”
