Prayer to Saint Michael the Archangel

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 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.
 
Pope Leo XIII wrote the Saint Michael prayer, in 1884, after supposedly seeing a frightening vision: evil spirits, trying to fulfill Satan’s boast to destroy our Lord’s Church within a century, were engaging in fierce attacks against it.
