The St. Michael Prayer: Full Text, History and the Long Version
Leo XIII's short prayer for the battle every Christian is already in
The St. Michael prayer is a short Catholic prayer asking St. Michael the Archangel to defend us against the devil: "St. Michael the Archangel, defend us in battle. Be our defense against the wickedness and snares of the devil..." Pope Leo XIII composed it and in 1886 ordered it said after every Low Mass, and Catholics have prayed it daily ever since. It is a prayer of petition, addressed to Michael and resting on the power of God, and any Catholic may pray it at any time.
This page gives you the exact text in English and Latin, its documented history, the truth about the famous vision story, what the "long St. Michael prayer" really is and why lay people should not use it, and how the prayer came back into parishes. Here is the plain fact: you are in a spiritual battle whether you pray or not. "Your adversary the devil prowls around like a roaring lion" (1 Peter 5:8). No one knows the day or the hour (Mark 13:32). Pray the prayer now, before you read the history.

1. The St. Michael Prayer: Exact Text
The St. Michael prayer has one standard English text, translated from Leo XIII's Latin. Small differences exist between prayer books ("defense" or "protection", "thrust" or "cast" into hell, "host" or "hosts"); they translate the same Latin words and are all correct.
1. Prayer to St. Michael the Archangel
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.
Approved traditional prayer, composed by Pope Leo XIII and prescribed after Low Mass in 1886.
2. Sancte Michael Archangele (Latin)
Sancte Michael Archangele, defende nos in proelio; 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.
The original Latin text of Leo XIII.
3. A Modern-Language Version
Saint Michael the Archangel, defend us in battle. Protect us against the wickedness and snares of the devil. May God rebuke him, we humbly pray. And you, Prince of the heavenly host, by the power of God, cast into hell Satan and all the evil spirits who prowl through the world seeking the ruin of souls. Amen.
The same prayer in contemporary English, as many parishes now say it after Mass.
Learn it by heart this week. It is sixty words long. Say it once a day for seven days and it will be yours for life.
2. Where Did the St. Michael Prayer Come From?
Pope Leo XIII composed the St. Michael prayer and, in 1886, added it to the prayers he had ordered to be said after every Low Mass. Those prayers, known as the Leonine Prayers, were first prescribed in 1884: three Hail Marys, the Hail, Holy Queen and a prayer for the Church. In 1886 Leo added the prayer to St. Michael. For roughly eighty years, priest and people knelt after the Low Mass and said them together, in parishes across the Latin Church.
Leo's purpose was the defence of the Church in a hostile age. He reigned from 1878 to 1903, when the papacy had lost the Papal States and faced fierce anticlerical governments in Europe. In 1930 Pope Pius XI directed that the Leonine Prayers be offered for the people of Russia, then under Soviet persecution of religion.
The Leonine Prayers were suppressed in the liturgical reform. The 1964 instruction Inter Oecumenici, which took effect in 1965, removed them from the end of Mass. The St. Michael prayer itself was never suppressed or discouraged; it simply stopped being required. Many Catholics kept saying it privately, and in recent decades many parishes have brought it back after Mass by local custom.
For Michael himself, his place in Scripture and his great shrines, read our profile of St. Michael the Archangel. For the Church's teaching on angels in general, see our guide to angels and the nine choirs.
3. Did Leo XIII Have a Vision Before Writing It?
A popular story says Leo XIII wrote the St. Michael prayer after a terrifying vision, and that story is unverified. In the usual telling, after celebrating Mass (often dated 13 October 1884) the Pope stopped, turned pale, and later said he had overheard Satan boast that he could destroy the Church if given enough time and power, and God allowing him a period of trial (75 or 100 years, depending on the version). Leo then went to his study and wrote the prayer.
Here is what is known. The written accounts appear decades after Leo's death in 1903. They disagree on important details: the date, the length of time granted, what Leo saw or heard, and who witnessed it. No contemporary document from Leo or his household confirms it, and Leo's own writings do not mention it. The story may preserve some real memory of how seriously Leo took the spiritual battle, or it may have grown in the retelling. Nobody can show which.
So hold it loosely. Do not build your faith on it, and do not pass it on as fact. You do not need it. The prayer stands on Scripture and on the authority of the Pope who wrote it, and the battle it describes is plain in the New Testament. Be very wary of anyone who uses the vision story to set dates or to claim the Church's end is scheduled. No one knows the day or the hour (Mark 13:32).
4. What the St. Michael Prayer Means, Line by Line
The St. Michael prayer packs the Bible's teaching on Michael and on spiritual warfare into a few lines. Pray it once slowly with these notes.
- "St. Michael the Archangel": Michael is named in Scripture as "one of the chief princes" (Daniel 10:13), "the great prince who has charge of your people" (Daniel 12:1), and "the archangel" (Jude 9). His name means "Who is like God?", which is the whole answer to Satan's pride.
- "defend us in battle": the battle is real and it is spiritual. "We are not contending against flesh and blood, but against the principalities, against the powers, against the world rulers of this present darkness" (Ephesians 6:12).
- "the wickedness and snares of the devil": the devil works mostly by deception and traps. "Put on the whole armor of God, that you may be able to stand against the wiles of the devil" (Ephesians 6:11).
- "May God rebuke him, we humbly pray": these words come from Jude 9, where even Michael "did not presume to pronounce a reviling judgment" on the devil, "but said, 'The Lord rebuke you.'" You do not take on Satan in your own name. You ask God to do it.
- "O Prince of the heavenly hosts, by the power of God": Michael's power is borrowed. Everything he does, he does by God's strength.
- "thrust into hell Satan": this echoes Revelation 12:7-9, where "Michael and his angels" fought the dragon, and "the great dragon was thrown down, that ancient serpent, who is called the Devil and Satan."
- "who prowl about the world seeking the ruin of souls": almost word for word from 1 Peter 5:8. The devil's goal is your soul. He is patient, and he is looking for your weak spot.
Notice the humility in it. The prayer never boasts, never commands the devil and never claims power of its own. That shape matters, and it is the key to the next two sections.

The "long St. Michael prayer" found online is usually taken from a different text: the Exorcism against Satan and the Apostate Angels, which Leo XIII published in 1890 for use by bishops and by priests authorised to perform exorcisms. It opens with a long invocation of St. Michael ("O glorious Prince of the heavenly host...") built on Ephesians 6:12 and Revelation 12, and then moves into the exorcism proper, which addresses Satan and the evil spirits directly and commands them in the name of Christ to depart.
An abbreviated form of that text was later placed in the Roman Ritual, and it remains in the current Rite of Exorcism (1999) among the prayers for particular circumstances of the Church. The rubric there places such prayer under the bishop, with meetings of the faithful held under the guidance of a priest. The short prayer to St. Michael, by contrast, appears in the same book among the prayers the faithful may use privately.
So there are two very different things going by the same name:
- The short St. Michael prayer (section 1): a petition to Michael, for everyone, everywhere, any time.
- The long "St. Michael prayer": in fact Leo XIII's exorcism formula, or an extract of it, written for authorised clergy.
This page does not reproduce the long text, for the reason given in the next section. If someone has handed you a printed "long St. Michael prayer", look at it carefully. If it contains direct commands to Satan or to evil spirits ("we drive you from us", "depart", "begone"), it is an exorcism text. Put it down and pray the short prayer.
6. Can Lay Catholics Pray the Long Version? The 1985 CDF Letter
Lay Catholics should not use the long version. In a letter to bishops dated 29 September 1985, known by its opening words Inde ab aliquot annis and signed by its prefect, Cardinal Joseph Ratzinger, the Congregation for the Doctrine of the Faith said it is not licit for the faithful to use the formula of exorcism against Satan and the apostate angels published by order of Leo XIII, whether in extracts or, still less, in its full text. Bishops were asked to remind the faithful of this.
The letter rests on canon 1172 of the Code of Canon Law, which says no one may lawfully perform exorcisms on the possessed without the special and express permission of the local bishop, who should grant it only to a priest of piety, knowledge, prudence and integrity of life. The same letter also asked bishops to stop people without that faculty from leading prayer meetings in which demons are addressed directly or questioned about their identity.
The distinction is simple:
- Deprecatory prayer (asking): you speak to God, to Mary, to Michael and the saints and ask them to deliver and protect. "May God rebuke him." Every Catholic may pray this way, for themselves and for others, at any time.
- Imperative prayer (commanding): you address the evil spirit directly and order it out. In the solemn form, over a possessed person, this is exorcism, reserved to a priest authorised by his bishop. Lay people should not command, interrogate or name demons over others.
Some writers argue that a strictly private, personal use of the long invocation is permitted, and the debate continues among priests and canonists. The safer course, and the one most consistent with the 1985 letter, is to leave Leo's 1890 text to the clergy. The International Association of Exorcists issued a warning in the same direction in 2020. Obedience here protects you. Recall the sons of Sceva, who tried to cast out demons in a name they did not know, and fled the house wounded (Acts 19:13-16).
The letter also stresses that none of this stops the faithful from praying, as Jesus taught us, to be delivered from evil. The Church gives you more than enough: the short St. Michael prayer, the Our Father, the Rosary, holy water, the sacraments. Our guide on casting out demons sets out in full what lay people may and may not do, and our guide to spiritual warfare gives a daily battle plan.
7. The Revival: John Paul II, Francis and the Dioceses
The St. Michael prayer has come back into wide use since the 1990s, pushed by popes and bishops. Here is the record:
- St. John Paul II, 1994. At the Regina Caeli on 24 April 1994, he noted that the prayer was once recited at the end of every Mass and asked Catholics not to forget it and to pray it for help in the battle against the forces of darkness and the spirit of this world, citing Ephesians 6.
- Pope Francis, 2013. On 5 July 2013, with Benedict XVI present, Francis blessed a new statue of St. Michael in the Vatican Gardens and consecrated Vatican City State to St. Joseph and St. Michael the Archangel, asking Michael to defend us from the Evil One.
- Pope Francis, 2018. In late September 2018, amid the abuse crisis and divisions in the Church, Francis asked Catholics to pray the Rosary every day in October and to end it with the ancient Marian prayer Sub tuum praesidium and the prayer to St. Michael, asking protection for the Church against the devil, who seeks to divide.
- Dioceses and parishes. Since 2018 many bishops, particularly in the United States, have asked or encouraged parishes to pray the St. Michael prayer after Mass, and many parishes that never dropped it kept going. It is a matter of local custom, so practice varies from parish to parish.
4. Sub Tuum Praesidium (We Fly to Thy Protection)
We fly to thy protection, O holy Mother of God. Despise not our petitions in our necessities, but deliver us always from all dangers, O glorious and blessed Virgin. Amen.
Approved traditional prayer, among the oldest known prayers to Mary. Pope Francis asked that it be prayed with the St. Michael prayer at the end of the Rosary in October 2018.
The lesson is plain. Three popes in a row, all well aware of how this prayer can be misused, have told Catholics to keep praying it. If your parish does not pray it after Mass, pray it yourself on the way out of the door.
8. How and When to Pray the St. Michael Prayer
Pray the St. Michael prayer daily, at a fixed time, and again whenever you are tempted or afraid. Here is a practical plan.
- Every morning, after the Morning Offering. Our page on Catholic morning prayer gives a 5-minute routine it fits into.
- After Mass, kneeling, whether or not the parish says it aloud.
- After the Rosary, following the Sub tuum, as Pope Francis asked in 2018. Our Rosary guide shows the full order.
- At night, after your examen. Our page on Catholic night prayer shows how.
- In temptation, the moment it starts. Say it under your breath. Then change what you are doing: leave the room, close the app, call someone.
- Over your home and family, walking through the house with holy water, praying it for those who live there.
- On the feast of the Archangels, 29 September (Michaelmas), go to Mass if you can.
Then do the harder part. The devil's usual footholds are ordinary ones: unconfessed sin, unforgiveness, occult dabbling and despair. Go to confession, forgive the person you are holding a grudge against, and throw out anything occult in your home. Our guide to tarot, astrology and the occult explains why.

9. More Prayers to St. Michael
Alongside Leo XIII's prayer, you can speak to St. Michael in your own words, as long as you keep the same shape: ask, and rely on God's power. These original prayers keep that shape.
5. For the Protection of My Family
St. Michael the Archangel, I place my family under your protection. Guard our home, our marriage and our children from every snare of the enemy. Where we have opened doors to evil by sin, help us close them through confession and prayer. Ask God to cover us with His peace tonight and every night. Who is like God? No one. Amen.
Original prayer by Catholic/Christian. "The angel of the LORD encamps around those who fear him, and delivers them." (Psalm 34:7)
6. In Temptation
St. Michael, I am being tempted right now, and I am weak. Stand with me. May God rebuke the tempter. Lord Jesus, You were tempted in every way and did not sin; give me Your strength for the next five minutes, and show me the way of escape You promised. Amen.
Original prayer by Catholic/Christian. "Submit yourselves therefore to God. Resist the devil and he will flee from you." (James 4:7)
7. For Those Who Protect Others
St. Michael, defender of God's people, watch over those who stand between us and harm: police officers, soldiers, firefighters, paramedics and all who keep watch at night. Keep them honest, brave and merciful. Bring them home safely, and if any of them die in service tonight, bring their souls to God. Amen.
Original prayer by Catholic/Christian. St. Michael is widely invoked as patron of police officers and soldiers.
8. For the Dying
St. Michael, the Church has long asked you to lead the souls of the faithful departed into the holy light. Stand by N. at the hour of death. Defend N. against fear and against every accusation of the enemy, and bring N. safely before the merciful face of Christ. Amen.
Original prayer by Catholic/Christian, echoing the Offertory of the traditional Requiem Mass, which asks that "the standard-bearer, holy Michael, lead them into the holy light."

Most Protestants do not pray to St. Michael, the Orthodox venerate him deeply, and Anglicans keep his feast. Here is each view, stated fairly.
- Protestants generally hold that prayer should be addressed to God alone, and they see asking angels or saints for help as unnecessary or wrong, citing 1 Timothy 2:5 ("one mediator between God and men"). Many still honour Michael as the archangel of Scripture and read Revelation 12 as a picture of Christ's victory.
- The Catholic response: asking Michael to pray and act for us no more replaces Christ's mediation than asking a friend to pray for you does. Every power Michael has is God's, and the prayer itself says "by the power of God". Scripture shows angels sent to help God's people again and again (Daniel 10:13; Acts 12:7-11; Hebrews 1:14).
- Eastern Orthodox Christians keep the Synaxis of the Archangel Michael and the Bodiless Powers on 8 November and pray to Michael often, with many churches dedicated to him.
- Anglicans keep Michaelmas, the feast of St. Michael and All Angels, on 29 September, a date also kept by Catholics and Lutherans.

11. Start Today: A 7-Day St. Michael Plan
The way to make the St. Michael prayer part of your life is to pray it at the same moment every day for a week, then build the rest of your defences around it.
- Day 1: learn the prayer by heart. Say it three times today.
- Day 2: read Revelation 12 and Jude 9. Pray the prayer slowly afterwards.
- Day 3: make an honest examen. What doors are open in your life? Write them down.
- Day 4: go to confession, or book it. Nothing closes doors like absolution. Our confession guide walks you through it.
- Day 5: clear out anything occult from your home and pray the prayer over each room with holy water.
- Day 6: forgive one person by name, out loud before God.
- Day 7: go to Mass and pray the prayer after it, kneeling. Keep going tomorrow.
Then make it permanent: morning, after Mass, after the Rosary, at night, and in every temptation. The devil hates a soul that prays every day, because that soul is hard to surprise.
Who is like God? No one. Live like you believe it.

Frequently Asked Questions
What are the words of the St. Michael prayer?
"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."
Who wrote the St. Michael prayer?
Pope Leo XIII wrote the St. Michael prayer and in 1886 added it to the Leonine Prayers said after every Low Mass. Those prayers were removed from the Mass in the liturgical reform of 1964 to 1965, but the prayer itself was never suppressed, and later popes encouraged Catholics to keep praying it.
Is the story of Leo XIII's vision true?
The story that Leo XIII wrote the prayer after a vision of Satan boasting he could destroy the Church is popular but unverified. Written accounts appear decades after his death in 1903, they disagree on key details, and no contemporary document confirms it. Hold it as a story of uncertain origin.
Can lay people pray the long St. Michael prayer?
Lay Catholics should not use the long version, which is usually taken from Leo XIII's 1890 Exorcism against Satan and the Apostate Angels. In 1985 the Congregation for the Doctrine of the Faith said the faithful may not use that exorcism formula, in extracts or in full (Inde ab aliquot annis). The short St. Michael prayer is for everyone.
What is the difference between the short and long St. Michael prayer?
The short prayer is a petition asking St. Michael to defend us, relying on God's power, and any Catholic may pray it. The long text is part of an exorcism formula written for bishops and authorised priests, and it includes direct commands to evil spirits, which the Church reserves to the clergy.
When should Catholics pray the St. Michael prayer?
Pray it daily: in the morning, after Mass, after the Rosary as Pope Francis asked in October 2018, at night, and at the first moment of temptation. St. John Paul II asked Catholics in 1994 not to forget it and to pray it for help in the spiritual battle.
Why do some parishes say the St. Michael prayer after Mass?
From 1886 until the mid-1960s, the St. Michael prayer was said after every Low Mass as one of the Leonine Prayers. The requirement ended in the liturgical reform, but many parishes have revived it by local custom, especially since 2018, when many bishops encouraged it during the abuse crisis.
Is it biblical to pray to St. Michael?
Scripture names Michael as an archangel and a prince who defends God's people (Daniel 10:13, 12:1; Jude 9; Revelation 12:7-9) and shows angels sent to help believers (Hebrews 1:14). Catholics ask his help the way they ask any friend of God to pray for them, while all power remains God's.
