A BRIEF EXPLANATION OF THE
O Antiphons
The O Antiphons are inspired by messianic titles taken from the book of Isaiah and are sung in the season of Advent in the days immediately preceding Christmas. They are sung at the Canticle of Mary (Magnificat) at Evening Prayer (Vespers) beginning on December 16th:
17 December: O Sapientia (O Wisdom)
18 December: O Adonai (O Lord)
19 December: O Radix Jesse (O Root of Jesse)
20 December: O Clavis David (O Key of David)
21 December: O Oriens (O Dayspring)
22 December: O Rex Gentium (O King of the Nations)
23 December: O Emmanuel (O With Us is God)
In addition, on December 23rd, in the Norbertine tradition, we sing an additional O Antiphon, O Virgo virginum (O Virgin of virgins).
The O Antiphons make up a lyrical paraphrase in the Christian hymn “O come, O come, Emmanuel” (in Latin, Veni Emmanuel).
FUN FACT
Also, if one were to take the first letter of these Latin titles in reverse order (Emmanuel, Rex, Oriens, Clavis, Radix, Adonai, Sapientia), it forms an acrostic of Ero cras, meaning, “Tomorrow I will be.”
ERO CRAS
"Tomorrow I will be."
At Saint Michael’s Abbey, since our tradition includes the antiphon about the Blessed Virgin Mary, the Latin wordsVero cras are formed, meaning, “Truly, tomorrow.”
