O Rex Gentium, O Antiphon for Dec. 22

Christ in Majesty, Fra Angelico

The O antiphon for Dec. 22nd begins by addressing our Savior with the Messianic name, O Rex Gentium. The antiphon then describes what this title symbolizes, and it ends with a petition, "come and ....”

O Rex Gentium, et desideratus earum, lapisque angularis, qui facis utraque unum:
veni, et salva hominem quem de limo formasti..

O King of the gentiles and their desired One, the cornerstone that makes both one: come, and deliver man, whom you formed out of the dust of the earth.

The word Gentium comes from gens, which means tribe, clan; nation, people; Gentiles. The Jews would have understood the word as referring to the Gentiles.

Calling on Christ as Rex Gentium et desideratus earum (King and desired one of all the nations) means that even those who have never heard of true God or His promised Messiah, and even those who do not know they need salvation, long for Him.

Scriptural Origins

King of the Nations
Jeremiah 10:7:7 Who would not fear thee, O King of the nations? For this is thy due; for among all the wise ones of the nations and in all their kingdoms there is none like thee.Desired of all nations
Haggai 2:4-8:
"My Spirit abides among you; fear not. For thus says the Lord of hosts: Once again in a little while, I will shake the heavens and the earth and the sea and the dry land; and I will shake all the nations — and the desired of all nations shall come; and I will fill this house with splendour, says the Lord of hosts."

Cornerstone
Psalm 118:22: "The stone which the builders rejected has become the head of the corner."

Isaiah 28:16a: "Behold, I am laying in Zion for a foundation a stone, a tested stone, a precious cornerstone, of a sure foundation."

Matthew 21:42, Mark 12:10, and Luke 20:17: "Jesus said to them, 'Have you never read in the scriptures: ‘The very stone which the builders rejected has become the head of the corner; this was the Lord’s doing, and it is marvelous in our eyes’?"

Acts 4:8-12:
⁸ Then Peter, filled with the Holy Spirit, said to them, “Rulers of the people and elders, ⁹ if we are being examined today concerning a good deed done to a cripple, by what means this man has been healed, ¹⁰ be it known to you all, and to all the people of Israel, that by the name of Jesus Christ of Nazareth, whom you crucified, whom God raised from the dead, by him this man is standing before you well. ¹¹ This is the stone which was rejected by you builders, but which has become the head of the corner. ¹² And there is salvation in no one else, for there is no other name under heaven given among men by which we must be saved.”

I Peter 2:7-8:

⁷ To you therefore who believe, he is precious, but for those who do not believe,

“The very stone which the builders rejected has become the head of the corner,”

⁸ and “A stone that will make men stumble, a rock that will make them fall”; for they stumble because they disobey the word, as they were destined to do.

Cornerstone Who Joins the Gentiles with Israel

Ephesians 2:14-16, 19-22:
¹¹ Therefore remember that at one time you Gentiles in the flesh, called the uncircumcision by what is called the circumcision, which is made in the flesh by hands— ¹² remember that you were at that time separated from Christ, alienated from the commonwealth of Israel, and strangers to the covenants of promise, having no hope and without God in the world. ¹³ But now in Christ Jesus you who once were far off have been brought near in the blood of Christ. ¹⁴ For he is our peace, who has made us both one, and has broken down the dividing wall of hostility, ¹⁵ by abolishing in his flesh the law of commandments and ordinances, that he might create in himself one new man in place of the two, so making peace, ¹⁶ and might reconcile us both to God in one body through the cross, thereby bringing the hostility to an end.  ¹⁹ So then you are no longer strangers and sojourners, but you are fellow citizens with the saints and members of the household of God, ²⁰ built upon the foundation of the apostles and prophets, Christ Jesus himself being the cornerstone, ²¹ in whom the whole structure is joined together and grows into a holy temple in the Lord; ²² in whom you also are built into it for a dwelling place of God in the Spirit.

Dom Gueranger's Commentary about Rex Gentium

O King of nations! Thou art approaching still nigher to Bethlehem, where Thou art to be born. The journey is almost over, and Thy august Mother, consoled and strengthened by the dear weight she bears, holds an unceasing converse with Thee on the way. She adores Thy divine Majesty; she gives thanks to Thy mercy; she rejoices that she has been chosen for the sublime ministry of being Mother to God. She longs for that happy moment when her eyes shall look upon Thee, and yet she fears it. For, how will she be able to render Thee those services which are due to Thy infinite greatness, she that thinks herself the last of creatures ? How will she dare to raise Thee up in her arms, and press Thee to her heart, and feed Thee at her breasts? When she reflects that the hour is now near at hand, in which, being born of her, Thou wilt require all her care and tenderness, her heart sinks within her; for, what human heart could bear the intense vehemence of these two affections—the love of such a Mother for her Babe, and the love of such a creature for her God? But Thou supportest her, O Thou the Desired of nations! for Thou, too, longest for that happy birth, which is to give to the earth its Saviour, and to men that corner-stone, which will unite them all into one family. Dearest King! be Thou blessed for all these wonders of Thy power and goodness ! Come speedily, we beseech Thee, come and save us, for we are dear to Thee, as creatures that have been formed by Thy divine hands. Yea, come, for Thy creation has grown degenerate; it is lost; death has taken possession of it: take Thou it again into Thy almighty hands, and give it a new creation; save it; for Thou hast not ceased to take pleasure in and love Thine own work.

From Julian of Norwich

O Rex Gentium
O King of our desire whom we despise,
King of the nations never on the throne,
Unfound foundation, cast-off cornerstone,
Rejected joiner, making many one,
You have no form or beauty for our eyes,
A King who comes to give away his crown,
A King within our rags of flesh and bone.
We pierce the flesh that pierces our disguise,
For we ourselves are found in you alone.
Come to us now and find in us your throne,
O King within the child within the clay,
O hidden King who shapes us in the play
Of all creation. Shape us for the day
Your coming Kingdom comes into its own.
