Sancte Michael Archangele, defende nos in praelio; contra nequitiam et insidias diaboli esto praesidium. Imperet illi Deus, supplices deprecamur: tuque, Princeps militiae caelestis, Satanam aliosque spiritus malignos, qui ad perditionem animarum pervagantur in mundo, divina virtute in infernum detrude. Amen.
St. Michael, the Archangel, defend us in battle; be our protection against the malice and snares of the devil. We humbly beseech God to command him; and do thou, O Prince of the heavenly hosts, by the divine power thrust into hell Satan and the other evil spirits who roam through the world seeking the ruin of souls. Amen.
