For some reason, I have the hardest time remembering this prayer, it could be that every other time I hear it, there seems to be a word or two changed. Doesn't matter though, it is still a very powerful prayer...

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.

The late (and great) pope John Paul II said this about this prayer:

'"May prayer strengthen us for the spiritual battle we are told about in the Letter to the Ephesians: 'Draw strength from the Lord and from His mighty power' (Ephesians 6:10). The Book of Revelation refers to this same battle, recalling before our eyes the image of St. Michael the Archangel (Revelation 12:7). Pope Leo XIII certainly had a very vivid recollection of this scene when, at the end of the last century, he introduced a special prayer to St. Michael throughout the Church. Although this prayer is no longer recited at the end of Mass, I ask everyone not to forget it and to recite it to obtain help in the battle against forces of darkness and against the spirit of this world."'

May St. Michael the Archangel be looking out for you this fine day.

God Bless!
