O Antiphon~ Rex Gentium

 Jesus Christ, King of all nations, came as a baby and would grow into the man who is  Lord of Lords and King of Kings. I have seen today's antiphon referred to as a "little Ash Wednesday" because we are reminded that from dust we were formed.
Jesus~who was, and is, and is to come. As we gaze upon the baby in the manger, may we also remember He is the Rex Gentium who came to live and die to save us.

O Rex Gentium(King of All Nations, King of the Gentiles)

O 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! 

Scripture:
Isaias 9:7
His empire shall be multiplied, and there shall be no end of peace: he shall sit upon the throne of David, and upon his kingdom; to establish it and strengthen it with judgment and with justice, from henceforth and for ever: the zeal of the Lord of hosts will perform this.

Isaias 2:4
And he shall judge the Gentiles, and rebuke many people: and they shall turn their swords into ploughshares, and their spears into sickles: nation shall not lift up sword against nation, neither shall they be exercised any more to war.
