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 the prophet said: “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 then Isaiah went on to say: “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) .

O come, Desire of nations, bind
In one the hearts of all mankind;
Bid every strife and quarrel cease
And fill the world with heaven's peace.
