O ADONAI

Antiphon sung by the Dominican student brothers at Blackfriars in Oxford.

December 18

O Adonai, et Dux domus Israel,
qui Moysi in igne flammæ rubi apparuisti,
et ei in Sina legem dedisti:
veni ad redimendum nos in brachio extento.

O Adonai, and Ruler of the house of Israel,
Who didst appear unto Moses in the burning bush,
and gavest him the law in Sinai,
come to redeem us with an outstretched arm!

Isaiah 11:4-5

But with righteousness he shall judge the poor,
and decide with equity for the meek of the earth;
he shall strike the earth with the rod of his mouth,
and with the breath of his lips he shall kill the wicked.
Righteousness shall be the belt around his waist,
and faithfulness the belt around his loins.

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."

O SAPIENTIA

Antiphon sung by the Dominican student brothers at Blackfriars in Oxford.

December 17

O Wisdom that comest out of the mouth of the Most High,
that reachest from one end to another,
and orderest all things mightily and sweetly,
come to teach us the way of prudence!

O Sapientia, quæ ex ore Altissimi prodiisti,
attingens a fine usque ad finem, fortiter
suaviterque disponens omnia:
veni ad docendum nos viam prudentiæ.

Isaiah 11:2-3

The spirit of the Lord shall rest on him,
the spirit of wisdom and understanding,
the spirit of counsel and might,
the spirit of knowledge and the fear of the Lord.
His delight shall be in the fear of the Lord.

He shall not judge by what his eyes see,
or decide by what his ears hear;

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."

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: 

Sapientia
Adonai
Radix Jesse
Clavis David
Oriens
Rex Gentium
Emmanuel
