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
