O MOST holy Angel of God, appointed by God to my Guardian, I give thee thanks for all the
benefits which thou hast ever bestowed on me in body and soul. I praise and glorify thee that thou
condescended to assist me with such patient fidelity, and to defend me against all the
assaults of my enemy. Blessed be the hour in which thou were assigned me for my Guardian,
my defender and my patron. In acknowledgment and return for all thy loving ministries to me, I
offer thee the infinitely precious and noble Heart of Jesus, and firmly purpose to obey thee
henceforward, and most faithfully to serve my God. Amen.


Offering of the Bitterness of Our Lord’s Passion

I offer to You, O Lord, all the bitterness of Your Passion, in reparation for the offenses committed against You.

“O” Antiphons

The Roman Church has been singing the "O" Antiphons since at least the eighth century. They are the antiphons that accompany the Magnificat canticle of Evening Prayer from December 17-23. They are a magnificent theology that uses ancient biblical imagery drawn from the messianic hopes of the Old Testament to proclaim the coming Christ as the fulfillment not only of Old Testament hopes, but present ones as well. Their repeated use of the imperative "Come!" embodies the longing of all for the Divine Messiah.
