commandments, hearkening unto the voice of his word.(Psalm 103:20)
Saint
Michael the Archangel, defend us in battle, be our defense against the
wickedness and snares of the devil. May God rebuke him, we humbly pray!
And do thou, prince of the heavenly hosts, by the power of God, thrust
into hell Satan and all the other evil spirits, who prowl about the
world, seeking the destruction of souls. Amen.
