O Antiphons of Advent- Praying as a Community

This post is mainly to serve as an informative post and/or reminder that the O Antiphons of Advent begin tomorrow (December 17th). The O Antiphons are part of an ancient tradition (as are most things Catholic) that involve seven responses, or antiphons, prayed seven days before the Eve of Christmas. Each of the antiphons begins with “O” and then a unique title for the Messiah, originating from Isaiah and Micah. Traditionally, the O Antiphons are sung before the Magnificat at evening prayer from December 17- 23th. Following a core purpose of CBC, I thought it fitting if we all committed to praying the O Antiphons on each of these next seven days preceding Christmas Eve, knowing that prayer is an important facet of communal living. This can serve as a great way to unite oneself with family, fellow CBC-ers and the Catholic Church around the world through pray and meditation on these antiphons together. Here they are below:

O Sapientia (O Wisdom)- December 17th.  Reflect on Isaiah 11:2–3; 28:29.

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 Adonai (O Lord)- December 18th. Reflect on Isaiah 11:4–5; 33:22.

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!

O Radix Jesse (O Root of Jesse)- December 19th. Reflect on Isaiah 1:1; 11:10.

Root of Jesse, which standest for an ensign of the people, at Whom the kings shall shut their mouths, Whom the Gentiles shall seek, come to deliver us, do not tarry.

O Clavis David (O Key of David)- December 20th. Reflect on Isaiah 9:6; 22:22.

Key of David, and Sceptre of the house of Israel, that openeth and no man shutteth, and shutteth and no man openeth, come to liberate the prisoner from the prison, and them that sit in darkness, and in the shadow of death.

O Oriens (O Rising Sun)- December 21st. Reflect on Isaiah 9:1.

Dayspring, Brightness of the everlasting light, Sun of justice, come to give light to them that sit in darkness and in the shadow of death!

O Rex Gentium (O King of the Nations)- December 22nd. Reflect on Isaiah 9:5; 2:4.

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 Emmanuel (God with us)- December 23rd. Reflect on Isaiah 7:14.

Emmanuel, our King and our Law-giver, Longing of the Gentiles, yea, and salvation thereof, come to save us, O Lord our God!


Pray the antiphon before and after the Magnificat for the next seven days before Christmas Eve.

Fun Fact: The first letter in each of the O Antiphons arranged backwards spells Ero Cras, which translates to mean “Tomorrow I come”.
