Today’s Jesse Tree devotion and O Antiphon celebrates Jesus as King of the Gentiles: Psalm 2:7-8; Ephesians 2:14-20

I will proclaim the decree of the LORD,
he said to me, “You are my son;
today I have begotten you.

Ask it of me,
and I will give you the nations as your inheritance,
and, as your possession, the ends of the earth.

For he is our peace, he who made both one and broke down the dividing wall of enmity, through his flesh, abolishing the law with its commandments and legal claims, that he might create in himself one new person in place of the two, thus establishing peace, and might reconcile both with God, in one body, through the cross, putting that enmity to death by it. He came and preached peace to you who were far off and peace to those who were near, for through him we both have access in one Spirit to the Father. So then you are no longer strangers and sojourners, but you are fellow citizens with the holy ones and members of the household of God, built upon the foundation of the apostles and prophets, with Christ Jesus himself as the capstone.

O Rex Gentium: “O King of all the nations, the only joy of every human heart; O Keystone of the mighty arch of man, come and save the creature you fashioned from the dust.” Isaiah had prophesied, “For a child is born to us, a son is given us; upon his shoulder dominion rests. They name him Wonder-Counselor, God-Hero, Father-Forever, Prince of Peace.” (9:5), and “He shall judge between the nations, and impose terms on many peoples. They shall beat their swords into plowshares and their spears into pruning hooks; one nation shall not raise the sword against another, nor shall they train for war again.” (2:4).
