The “Great O” Antiphons

December 17 – The “Great O” Antiphons begin at Vespers as Magnificat antiphons – The importance of the “O Antiphons” is twofold. First, each one is a title for the Messiah. Secondly, each one refers to the prophecy of Isaiah of the coming of the Messiah. The Latin antiphons are from the Breviarium Romanum.

O Sapientia

O 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.
Isaiah had prophesied.
