One of the oldest and most enduring features of Advent in the Western tradition of the Church is the special set of antiphons sung with the Magnificat at Vespers in the days leading up to Christmas Eve. Usually called the “Greater Antiphons” in liturgical books, they’re more colloquially called the “O Antiphons” because each begins with the interjection “O” (O Emmanuel…, etc.).
The oldest and most traditional set of O Antiphons address Christ by seven titles, in this order: Sapientia (Wisdom), Adonai (Lord), Radix Jesse (Root of Jesse), Clavis David (Key of David), Oriens (Dayspring/Dawn), Rex Gentium (King of the Nations/Gentiles), and Emmanuel (God-with-us). The first letters of each title going back from Emmanuel (Dec 24) to Sapientia (Dec 17) form the Latin words Ero cras, meaning “Tomorrow I come.” The content of these antiphons was paraphrased as the verses to the Latin hymn Veni Emmanuel, translated into our familiar English hymn, O Come, O Come Emmanuel. While the history of the antiphons and their use is fascinating in itself, the most wonderful thing about them is the theology and spiritual learning that can be unpacked from these pithy poems.
Below are a series of videos produced by my home parish (Church of the Advent in Atlanta, GA) which explore the titles used to address Christ in each of the O Antiphons and the contexts of those titles. Click here for a YouTube playlist of all the videos, or just watch them individually here.
