St. Michael the Archangel led the army of god against Lucifer (Satan) and the fallen angels. St. Michael the Archangel is the patron saint of sailors (mariners). The name Michael means “who is like God”.
St. 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,
O Prince of the heavenly hosts,
by the power of God,
thrust into hell Satan,
and all the evil spirits,
who prowl about the world
seeking the ruin of souls. Amen
