Are you Elijah?” And he said, “I am not.” “Are you the Prophet?” And he answered, “No.” - 22 Therefore, they said to him: “Who are you, so that we may give an answer to those who sent us? What do you say about yourself?” - 23 He said, “I am a voice crying out in the desert, ‘Make straight the way of the Lord,’ just as the prophet Isaiah said.” - 24 And some of those who had been sent were from among the Pharisees. - 25 And they questioned him and said to him, “Then why do you baptize, if you are not the Christ, and not Elijah, and not the Prophet?” - 26 John answered them by saying: “I baptize with water. But in your midst stands one, whom you do not know. - 27 The same is he who is to come after me, who has been placed ahead of me, the laces of whose shoes I am not worthy to loosen.” - 28 These things happened in Bethania, across the Jordan, where John was baptizing.

In US parishes the readings are proclaimed from the NABRE; the text shown here is the Catholic Public Domain Version. Old Testament readings and the psalm are listed with a link to their chapter: the US Lectionary numbers some of their verses differently from the CPDV, so their text is not printed here. Psalm citations keep the Lectionary’s Hebrew numbering; the CPDV numbers the Psalms as the Vulgate does. Spotted a wrong date, color or citation?
