Second Reading: 1 Thessalonians 5:16-24
16Rejoice always, 17pray without ceasing, 18give thanks in all circumstances; for this is the will of God in Christ Jesus for you. 19Do not quench the Spirit. 20Do not despise the words of prophets, 21but test everything; hold fast to what is good; 22abstain from every form of evil.
23May the God of peace himself sanctify you entirely; and may your spirit and soul and body be kept sound and blameless at the coming of our Lord Jesus Christ. 24The one who calls you is faithful, and he will do this.
Gospel: John 1:6-8, 19-28
6There was a man sent from God, whose name was John. 7He came as a witness to testify to the light, so that all might believe through him. 8He himself was not the light, but he came to testify to the light.
19This is the testimony given by John when the Jews sent priests and Levites from Jerusalem to ask him, “Who are you?” 20He confessed and did not deny it, but confessed, “I am not the Messiah.” 21And they asked him, “What then? Are you Elijah?” He said, “I am not.” “Are you the prophet?” He answered, “No.” 22Then they said to him, “Who are you? Let us have an answer for those who sent us. What do you say about yourself?” 23He said, “I am the voice of one crying out in the wilderness, ‘Make straight the way of the Lord,’ ” as the prophet Isaiah said.
24Now they had been sent from the Pharisees. 25They asked him, “Why then are you baptizing if you are neither the Messiah, nor Elijah, nor the prophet?” 26John answered them, “I baptize with water. Among you stands one whom you do not know, 27the one who is coming after me; I am not worthy to untie the thong of his sandal.” 28This took place in Bethany across the Jordan where John was baptizing.
