In some liturgical traditions the O Antiphons are used in the evening office (the hours, the daily office) during the last week leading up to Christmas Eve.
Each antiphon is a name of Christ, one of his attributes mentioned in Scripture.
- December 17: O Sapientia (O wisdom)
- December 18: O Adonai (O Adonai)
- December 19: O Radix Jesse (O Root of Jesse)
- December 20: O Clavis David (O Key of David)
- December 21: O Oriens (O Morning Star)
- December 22: O Rex Gentium (O King of the nations)
- December 23: O Emmanuel (O Emmanuel)
These antiphons were arranged with a definite purpose in mind. If you start with the last title and take the first letter of each one—Emmanuel, Rex, Oriens, Clavis, Radix, Adonai, Sapientia—the Latin words ero cras are formed.They mean, "Tomorrow, I will come". Jesus, whose coming is at the heart of Advent and who has been addressed in these seven Messianic titles,speaks to the celibrant: "Tomorrow, I will come." The " O Antiphons" not only engage the heart in Advent preparation, but bring a joyful conclusion as well.
