First Reading (Isaiah 11, 1-10)
On that day, a shoot will come up from the stump of Jesse; from his roots a Branch will bear fruit. The Spirit of the Lord will rest on him—the Spirit of wisdom and of understanding, the Spirit of counsel and of power, the Spirit of knowledge and of the fear of the Lord—and he will delight in the fear of the Lord. He will not judge by what he sees with his eyes, or decide by what he hears with his ears; but with righteousness he will judge the needy, with justice he will give decisions for the poor of the earth. He will strike the earth with the rod of his mouth; with the breath of his lips he will slay the wicked. Righteousness will be his belt and faithfulness the sash around his waist. The wolf will live with the lamb, the leopard will lie down with the goat, the calf and the lion and the yearlingtogether; and a little child will lead them. The cow will feed with the bear, their young will lie down together,and the lion will eat straw like the ox. The infant will play near the hole of the cobra, and the young child put his hand into the viper’s nest. They will neither harm nor destroy on all my holy mountain, for the earth will be full of the knowledge of the Lordas the waters cover the sea. In that day the Root of Jesse will stand as a banner for the peoples; the nations will rally to him, and his place of rest will be glorious.
Second Reading (Rm 15, 4-9)
Brothers and sisters : For everything that was written in the past was written to teach us, so that through endurance and the encouragement of the Scriptures we might have hope. May the God who gives endurance and encouragement give you a spirit of unity among yourselves as you follow Christ Jesus, so that with one heart and mouth you may glorify the God and Father of our Lord Jesus Christ. Accept one another, then, just as Christ accepted you, in order to bring praise to God. For I tell you that Christ has become a servant of the Jewson behalf of God’s truth, to confirm the promises made to the patriarchs so that the Gentiles may glorify God for his mercy, as it is written: “Therefore I will praise you among the Gentiles; I will sing hymns to your name.”
The Gospel (Mt 3, 1-12)
In those days John the Baptist came, preaching in the Desert of Judea and saying, “Repent, for the kingdom of heaven is near.” This is he who was spoken of through the prophet Isaiah: “A voice of one calling in the desert, ‘Prepare the way for the Lord, make straight paths for him.’” John’s clothes were made of camel’s hair, and he had a leather belt around his waist. His food was locusts and wild honey. People went out to him from Jerusalem and all Judea and the whole region of the Jordan. Confessing their sins, they were baptized by him in the Jordan River. But when he saw many of the Pharisees and Sadducees coming to where he was baptizing, he said to them: “You brood of vipers! Who warned you to flee from the coming wrath? Produce fruit in keeping with repentance. And do not think you can say to yourselves, ‘We have Abraham as our father.’ I tell you that out of these stones God can raise up children for Abraham. The ax is already at the root of the trees, and every tree that does not produce good fruit will be cut down and thrown into the fire. “I baptize you withwater for repentance. But after me will come one who is more powerful than I, whose sandals I am not fit to carry. He will baptize you with the Holy Spirit and with fire. His winnowing fork is in his hand, and he will clear his threshing floor, gathering his wheat into the barn and burning up the chaff with unquenchable fire.”
