O most holy angel of God,
appointed by God to be my guardian,
I give you thanks for all the benefits
which you have ever bestowed on me
in body and in soul.
I praise and glorify you
that you condescended to assist me
with such patient fidelity,
and to defend me against all the assaults of my enemies.
Blessed be the hour in which
you were assigned me for my guardian,
my defender and my patron.
In acknowledgement and return
for all your loving ministries to me,
I offer you the infinitely precious
and noble heart of Jesus,
and firmly purpose to obey you henceforward,
and most faithfully to serve my God.
Amen
