Yesterday, we began using the O Antiphons in evening services. The great Os, as they are sometimes called, are used during the last seven days of Advent. Each begins with an O and is based on the prophecy of Isaiah about the coming of the Messiah. Each includes a name associated with Jesus Christ.
Learn more about each Great O and celebrate the”Wisdom, coming forth from the mouth of the Most High, reaching from one end to the other,
mightily and sweetly ordering all things: Come and teach us the way of prudence.”
