The prayer to St. Michael invokes the protection of the archangel Michael in the ongoing spiritual battle for the souls of all mankind. This prayer was composed by Pope Leo XIII and its use was instituted in 1886 at the end of Low Mass, a tradition which continued until the liturgical reforms of the Second Vatican Council. A popular story regarding its origin claims that the Pope wrote this prayer after having a vision of demonic spirits descending on Rome.

Michael is mentioned as one of God’s seven archangels in the Book of Enoch and is presented by Revelations 12:7-12 as the warrior angel who cast Satan from heaven. He is therefore traditionally venerated as a protector against the forces of evil and a guardian of the Church.

The Prayer to St. Michael is still commonly said at the end of the rosary and by some parishes after the conclusion of Mass.

St. 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. .

O glorious prince St. Michael, 
chief and commander of the heavenly hosts, 
guardian of souls, vanquisher of rebel spirits, 
servant in the house of the Divine King
and our admirable conductor, 
you who shine with excellence
and superhuman virtue deliver us from all evil,
who turn to you with confidence
and enable us by your gracious protection
to serve God more and more faithfully every day.
