We compel thee, Michael the Archangel, to defend us in conflict; wrap your wings around us and protect us against hatred and the wicked. By the power bestowed upon you, send for your legion of angels; have them walk among us and be at our side from this day forward to watch over us. So mote it be. (written by Julie M. Perkins, October 2017)

The original short version of the prayer written by Pope Leo XIII:

Holy Michael, the Archangel, defend us in battle. Be our safeguard against the wickedness and snares of the devil. May God rebuke him, we humbly pray; and do you, O Prince of the heavenly host, by the power of God cast into hell Satan and all the evil spirits who wander through the world seeking the ruin of souls. Amen.

Sáncte Míchael Archángele, defénde nos in proélio, cóntra nequítiam et insídias diáboli ésto præsídium. Ímperet ílli Déus, súpplices deprecámur: tuque, prínceps milítiæ cæléstis, Sátanam aliósque spíritus malígnos, qui ad perditiónem animárum pervagántur in múndo, divína virtúte, in inférnum detrúde. Ámen
