Prayers
to Saint Michael the Archangel
Saint Michael the Archangel
Prince of the heavenly host.
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 power of God,
cast into hell Satan
and all the evil spirits
who prowl about the world
seeking the ruin of souls.
Amen.
PRAYER OF SAINT ALOYSIUS
TO SAINT MICHAEL
O Victorious Prince,
most humble guardian
of the Church of God
and of the faithful souls,
who with such charity and zeal
took part in so many conflicts
and gained such great victories
over the enemy for the conservation
and protection of the honor
and glory we all owe to God,
as well as for the promotion
of man's salvation;
come, I pray thee,
to the assistance of my soul,
which continually is besieged
with such great peril by its enemies,
the flesh, the world, and the devil.
And as you were a leader
for the people of Israel
through the desert,
so also be my faithful leader
and companion
through the desert of this world,
until you conduct me safely
into the happy land of the living,
in that blessed fatherland
from which we all are exiles. 
Amen.

Revelation 12, 7-8
Then war broke out in heaven; Michael and his angels battled against the dragon. The dragon and its angels fought back, but they did not prevail and there was no longer any place for them in heaven.
Jude 9
Yet the archangel Michael, when he argued with the devil in a dispute over the body of Moses, did not venture to pronounce a reviling judgment upon him but said, “May the Lord rebuke you!”
Daniel 12, 1
“At that time there shall arise Michael, the great prince, guardian of your people; It shall be a time unsurpassed in distress since the nation began until that time. At that time your people shall escape, everyone who is found written in the book.
