THE seven "O Antiphons" (also called the "Greater Antiphons" or "Major Antiphons") are prayers that come from the Breviary's Vespers during the Octave before Christmas Eve, a time which is called the "Golden Nights." The week leading up to Christmas EVE.
Each Antiphon begins with "O" and addresses Jesus with a unique title which comes from the prophecies of Isaias and Micheas (Micah), and whose initials, when read backwards, form an acrostic for the Latin "Ero Cras" which means "Tomorrow I come." Those titles for Christ are:
These titles in more detail:
Dec. 17th Sapientia
And the spirit of the Lord shall rest upon him: the spirit of wisdom, and of understanding, the spirit of counsel, and of fortitude, the spirit of knowledge, and of godliness. And he shall be filled with the spirit of the fear of the Lord, He shall not judge according to the sight of the eyes, nor reprove according to the hearing of the ears.
This also is come forth from the Lord God of hosts, to make his counsel wonderful, and magnify justice.
Lord of Israel
But he shall judge the poor with justice, and shall reprove with equity the meek of the earth: and he shall strike the earth with the rod of his mouth, and with the breath of his lips he shall slay the wicked. And justice shall be the girdle of his loins: and faith the girdle of his reins.
For the Lord is our judge, the Lord is our lawgiver, the Lord is our king: he will save us.
Root of Jesse
And there shall come forth a rod out of the root of Jesse, and a flower shall rise up out of his root.
In that day the root of Jesse, who standeth for an ensign of the people, him the Gentiles shall beseech, and his sepulchre shall be glorious.
Now shalt thou be laid waste, O daughter of the robber: they have laid siege against us, with a rod shall they strike the cheek of the judge of Israel.
For I say that Christ Jesus was minister of the circumcision for the truth of God, to confirm the promises made unto the fathers. But that the Gentiles are to glorify God for his mercy, as it is written: Therefore will I confess to thee, O Lord, among the Gentiles, and will sing to thy name. And again he saith: Rejoice, ye Gentiles, with his people. And again: Praise the Lord, all ye Gentiles; and magnify him, all ye people. And again Isaias saith: There shall be a root of Jesse; and he that shall rise up to rule the Gentiles, in him the Gentiles shall hope. Now the God of hope fill you with all joy and peace in believing; that you may abound in hope, and in the power of the Holy Ghost.
And I saw in the right hand of him that sat on the throne, a book written within and without, sealed with seven seals. And I saw a strong angel, proclaiming with a loud voice: Who is worthy to open the book, and to loose the seals thereof? And no man was able, neither in heaven, nor on earth, nor under the earth, to open the book, nor to look on it. And I wept much, because no man was found worthy to open the book, nor to see it. And one of the ancients said to me: Weep not; behold the lion of the tribe of Juda, the root of David, hath prevailed to open the book, and to loose the seven seals thereof.
Key of David
And I will lay the key of the house of David upon his shoulder: and he shall open, and none shall shut: and he shall shut, and none shall open.
For a child is born to us, and a son is given to us, and the government is upon his shoulder: and his name shall be called Wonderful, Counsellor, God the Mighty, the Father of the world to come, the Prince of Peace.
Radiant Dawn, Dayspring
The people that walked in darkness, have seen a great light: to them that dwelt in the region of the shadow of death, light is risen.
For behold the day shall come kindled as a furnace: and all the proud, and all that do wickedly shall be stubble: and the day that cometh shall set them on fire, saith the Lord of hosts, it shall not leave them root, nor branch. But unto you that fear my name, the Sun of justice shall arise, and health in his wings: and you shall go forth, and shall leap like calves of the herd. And you shall tread down the wicked when they shall be ashes under the sole of your feet in the day that I do this, saith the Lord of hosts.
King of all Nations, King of the Gentiles
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.
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.
God with us
Therefore the Lord himself shall give you a sign. Behold a virgin shall conceive, and bear a son and his name shall be called Emmanuel.
