St. Michael the Archangel Prayer - Sancte Michael Archangele - by Pope Leo XIII
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, O Prince of the Heavenly Host, by the power of God, thrust into hell Satan and all the evil spirits who prowl about the world for the ruin of souls.
Sancte Michael Archangele, defende nos in proelio, contra nequitiam et insidias diaboli esto praesidium. Imperet illi Deus, supplices deprecamur: tuque, Princeps Militiae Coelestis, satanam aliosque spiritus malignos, qui ad perditionem animarum pervagantur in mundo, divina virtute, in infernum detrude.
