The antiphon for 22nd December is O Rex Gentium (O King of Nations, or O King of the Gentiles):
King of the Gentiles, yea, and desire thereof! O Corner-stone, that makest of two one, come to save man, whom Thou hast made out of the dust of the earth!
O Rex Gentium, et desideratus earum, lapisque angularis, qui facis utraque unum: veni, et salva hominem, quem de limo formasti.

The long awaited Messiah of the Jews comes as a king for all nations. In a reversal of the expected order of things, he does not conquor by force, nor is he born into a ruling family (though he is of royal lineage). At his first coming Christ has the humblest of beginnings: poverty, homelessness, feeble flesh; but in these last days before Christmas we are reminded of the last days before Advent and the feast in Christ the King. Advent remembers the first coming and anticipates the second. When he comes again we shall see him in his Glory. We shall know him as King.
