Belief in the one God is professed because he has revealed himself to the people of Israel as the only One when he said, “Hear, O Israel, the Lord our God is one Lord” (Deuteronomy 6:4) and “there is no other” (Isaiah 45:22). Jesus himself confirmed that God is “the one Lord” (Mark 12:29). To confess that Jesus and the Holy Spirit are also God and Lord does not introduce any division into the one God. (Catechism of the Catholic Church Comp. n. 37)

Readings: 2nd Sunday in Ordinary Time

Reading I: Is 42:1-4, 6-7

Thus says the LORD: Here is my servant whom I uphold, my chosen one with whom I am pleased, upon whom I have put my spirit; he shall bring forth justice to the nations, not crying out, not shouting, not making his voice heard in the street. A bruised reed he shall not break, and a smoldering wick he shall not quench, until he establishes justice on the earth; the coastlands will wait for his teaching. I, the LORD, have called you for the victory of justice, I have grasped you by the hand; I formed you, and set you as a covenant of the people, a light for the nations, to open the eyes of the blind, to bring out prisoners from confinement, and from the dungeon, those who live in darkness.

   R. The Lord will bless his people with peace.

Reading II: Ti 2:11-14; 3:4-7

Beloved: The grace of God has appeared, saving all and training us to reject godless ways and worldly desires and to live temperately, justly, and devoutly in this age, as we await the blessed hope, the appearance of the glory of our great God and savior Jesus Christ, who gave himself for us to deliver us from all lawlessness and to cleanse for himself a people as his own, eager to do what is good. When the kindness and generous love of God our savior appeared, not because of any righteous deeds we had done but because of his mercy, He saved us through the bath of rebirth and renewal by the Holy Spirit, whom he richly poured out on us through Jesus Christ our savior, so that we might be justified by his grace and become heirs in hope of eternal life.

Alleluia: Cf. Mk 9:7

1. Alleluia, alleluia.
   The heavens were opened and the voice of the Father thundered:
   This is my beloved Son, listen to him.
   R. Alleluia, alleluia.

Gospel: Lk 3:15-16, 21-22

The people were filled with expectation, and all were asking in their hearts whether John might be the Christ. John answered them all, saying, “I am baptizing you with water, but one mightier than I is coming. I am not worthy to loosen the thongs of his sandals. He will baptize you with the Holy Spirit and fire.” After all the people had been baptized and Jesus also had been baptized and was praying, heaven was opened and the Holy Spirit descended upon him in bodily form like a dove. And a voice came from heaven, “You are my beloved Son; with you I am well pleased.”
