Saint Michael the Archangel...

Saint Michael the Archangel,
defend us in battle.
Be our protection against the
wickedness and snares of the devil.
May God rebuke him, we humbly pray;
and do Thou, O Prince of the Heavenly Host -
by the Divine Power of God -
cast into hell, Satan and all the evil spirits,
who roam throughout the world
seeking the ruin of souls.

Amen.
