The O Antiphons
- The O Antiphons are the seven responses that introduce the canticle of Mary (the Magnificat) at evening prayer from December 17 to December 23. They are based on Isaiah’s prophecies and refer to the different ancient titles given to the Messiah. The O Antiphons are the basis for the Advent song, O Come, O Come, Emmanuel.
