Dec. 20, 2020 – The ‘O Antiphons’ – O Key of David


The Great Advent O Antiphons are seven responses that are sung to introduce the canticle of Mary from December 17 to December 23. These antiphons are based on Isaiah’s prophecies and refer to the different ancient titles given to the Messiah: O Wisdom; O Lord; O Root of Jesse; O Key of David; O Morning Star; O King of the Nations and O Emmanuel.
