Latin:

Sancte Michael Archangele, defende nos in proelio, contra nequitiam et insidias diaboli esto praesidium. Imperet illi Deus, supplices deprecamur: tuque, Princeps militiae caelestis, in virtute Dei, in infernum detrude satanam aliosque spiritus malignos, qui ad perditionem animarum pervagantur in mundo.

Amen.

 

English:

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, thrust into hell satan and all the evil spirits who prowl about the world seeking the ruin of souls.

Amen.
