O most holy Angel of God, appointed by God
to be 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.
