The O Antiphons constitute one of the oldest of Christian prayers. Referred to most commonly as the “O” Antiphons, it is also known as the “Greater” Antiphons, and “The Seven O’s.” Each one begins with letter “O” followed by name being invoked: Sapientia, Adonia, Radix, Jesse, Clavis David, Oriens, Rex Gentium, Emmanuel.

If read in reverse order, “The Seven O” prayers mean “Ero Cras” or “Tomorrow I will come” (actually, “Tomorrow I will be”). By the way, this kind of word-play is not really liturgical, so most likely it’s a bored medieval monk who came up with the significance of the backwards acrostic.  But it is fun to showcase this.

Here is the summary form of “The Seven O” Prayers:

Dec. 17: O Sapientia (I)

Dec. 18: O Adonai (II) plus O Virgo virginum (O Blessed Virgin Mary)

Dec. 19: O Radix Jesse (III)

Dec. 20: O Clavis David (IV), plus O Gabriel!

Dec. 21: O Oriens (V)

Dec. 22: O Rex Gentium (VI), plus O Rex pacifice

Dec. 23: O Emmanuel (VII), plus O Hierusalem!

Dec. 24:  Christmas Eve – The Vigil Of Christmas

These seven antiphons were recited as a part of the evening Vespers prayers of the pre-Reformation church before and after The Magnificat in the Octave before Christmas, December 17 to 23 (the Vespers for Dec. 24, Christmas Eve, are those for the Christmas Vigil). Prior to the Reformation, it was sung from 16 to 23 December, omitting St. Thomas’ Day (December 21). These last seven days of Advent are also known as the Greater Ferias.

Each antiphon links a prophecy of Isaiah to its fulfilment in the gospel. They survived through the centuries, even through the Protestant Reformation, though the dates on which they were sung changed and became more flexible. While they can be used on the exact days for which they were designed, they also can become an entire Advent service, or scattered throughout Advent in meaningful and intentional ways.

These antiphons became carols, the oldest of which is the one that brings the seven together into one song: “O Come, O Come Emmanuel.” The tune to which we now sing “O Come, O Come Emmanuel” began as a funeral litany.

Each of the seven stanzas addressed the Messiah by one of his titles, each one praising the coming of the Savior by a different name, and closing with petitions appropriate to the title. Thus:

Address and Praise:

     O EMMANUEL, God with us, Our King and Lawgiver, the expected of the nations and their Savior:

Closing Petition:

     COME to save us, O Lord our God. Amen.

One verse was sung or chanted each evening (as opposed to being sung together as a single hymn, as we do today).

According to one source, on December 17th the Abbot would intone the first Antiphon, O Sapientia. On successive nights, each principal officer of the monastery would take his turn with another of the Antiphons. After the service, the officer was expected to provide some sort of treat, usually edible, for all the monks.
