Introduction: A forgotten legacy, a present urgency
In a world where faith is diluted, churches are emptied, and evil grows bolder, the Church possesses spiritual treasures that seem to have been relegated to oblivion despite their immense power. One such treasure is the Leonine Prayers, also known as the “Leonine Supplications”, a set of powerful pleas once recited at the end of every Low Mass and instituted by Pope Leo XIII. These prayers are a simple yet tremendously powerful spiritual weapon—urgently needed in these times when confusion and apostasy have infiltrated even the heart of the sacred.
This article is an invitation to rediscover, understand, appreciate, and resume the fervent use of these prayers. They are not merely pious traditions from the past, but profoundly theological and pastoral acts that connect us to the heart of the spiritual battle of our time.
I. Origin of the Leonine Prayers: a prophetic response to the assault of evil
The Leonine Prayers originated in the 19th century, specifically in 1884, when Pope Leo XIII, after a mystical vision that would mark his pontificate, instituted a series of public prayers to be said after Mass.
According to a widely circulated and piously accepted tradition, Pope Leo XIII had a terrifying vision after celebrating Mass in the Vatican chapel: he saw Satan asking God for permission to tempt and destroy the Church over the course of a century. This vision so profoundly impacted the Holy Father that he immediately retired to his office and composed a special prayer to Saint Michael the Archangel, imploring his protection over the universal Church.
Alongside this prayer, he instituted a set of public prayers, known as the Leonine Supplications, to be recited kneeling after each Low Mass, for the liberty of the Church and the conversion of sinners. Other intentions were later added: world peace, the defense of the Papacy, and, after the seizure of the Papal States, the restoration of the Pope’s temporal power.
II. What are the Leonine Prayers?
The original set included:
- Three Hail Marys
- One Hail Holy Queen (Salve Regina)
- A versicle and response:
– V. Pray for us, O Holy Mother of God.
– R. That we may be made worthy of the promises of Christ. - A concluding prayer:
– “O God, our refuge and our strength…” (a plea for the liberty of the Church) - Prayer to Saint Michael the Archangel:
– “Saint Michael the Archangel, defend us in battle…” - Triple invocation to the Sacred Heart of Jesus:
– “Most Sacred Heart of Jesus, have mercy on us” (three times)
Although simple, these prayers form a miniature liturgy—fervent and focused—that encompasses Marian, Christological, and angelic elements, encapsulating the Catholic spiritual life in combat mode.
III. Deep theological meaning: the Church in combat
The Leonine Prayers were never intended as mere devotional formulas. They are an intense expression of the ecclesia militans, that is, the Church as a community engaged in spiritual battle against the forces of evil.
- Christocentric and Marian Dimension:
The three Hail Marys and the Salve Regina remind us of the constant intercession of the Virgin Mary, who is “terrible as an army set in battle array” (cf. Song of Songs 6:10), and a powerful advocate in the battles of the soul. - Angelic and Apocalyptic Dimension:
The prayer to Saint Michael recalls the battle described in Revelation 12:7-9, where Michael and his angels fight against the Dragon. In this context, the prayer is not merely symbolic but a real plea for heavenly intervention in the invisible war fought for souls. - Ecclesiological Dimension:
The supplication for the freedom of the Church, especially from worldly powers, reflects a clear vision: the Church will always be under siege, but never defeated, and constantly needs the prayers of the faithful to sustain her. - Sacrificial and Missionary Dimension:
Prayed immediately after the Sacrifice of the Altar, these prayers extended the spirit of the Mass into the realm of mission, the defense of the faith, and the salvation of souls.
IV. History and suppression: from fervor to forgetfulness
For more than 80 years, the Leonine Prayers were a regular part of the Church’s liturgical life. But in 1964, during the liturgical reform process leading up to the Missal of Paul VI, they were suppressed without a compelling theological explanation.
Nevertheless, they were never condemned. In fact, many faithful and traditional communities still pray them today, especially after the Traditional Latin Mass. The Priestly Fraternity of Saint Pius X, the Institute of Christ the King, and other communities committed to the Vetus Ordo have kept this tradition alive as a concrete form of spiritual resistance.
V. Practical applications today: returning to the fight on our knees
The relevance of the Leonine Prayers cannot be overstated. In a time marked by:
- Internal doctrinal attacks,
- Ideological persecution of Christians worldwide,
- Moral confusion even among the clergy,
- Loss of the sense of the sacred and abandonment of the faith,
these prayers offer a path of reparation, supplication, and spiritual militancy. How can we integrate them into our daily lives?
1. Pray the Supplications after Mass, even privately
If you attend a Mass where they are not recited, you can pray them yourself afterward. No permission is needed: it is private prayer with a public intention.
2. Form small groups to pray them together
A family, a prayer group, a school community—any small spiritual army can incorporate these supplications into their regular routine.
3. Live their spirit daily
Beyond the words, these prayers teach us to live aware of spiritual combat. As Saint Peter reminds us:
“Be sober and vigilant. Your adversary the devil prowls around like a roaring lion, seeking someone to devour.” (1 Peter 5:8)
4. Keep them printed and visible
Having these prayers on your nightstand, in your missal, or next to your rosary is a reminder that the Christian life is not a spiritual vacation, but a battle for eternity.
VI. Why pray them today? A cry from the persecuted Church
Today, when it seems the smoke of Satan has entered the sanctuary itself (as Pope Paul VI warned), and when faith is being reduced to mere sentiment or humanitarianism, the Leonine Prayers stand as a silent but powerful proclamation: the Church does not surrender; she fights on her knees.
Like Saint Michael, like Mary, like the saints of all times, today’s Christian is called to resist evil not just with words, but with fervent prayer, trusting that the final victory belongs to God.
Conclusion: On our knees, but in battle
The Leonine Prayers are, ultimately, a prophetic act of trust, a Marian supplication, an ecclesial cry, and a communal exorcism. They require no new approval because they were never abrogated. They are still here—like a sword sheathed, waiting for hands willing to wield it with faith.
To return to these prayers is not nostalgia or spiritual archaeology: it is obedience to a prophetic call from the past that echoes urgently in the present.
May each of us, as members of the Mystical Body of Christ, take up this powerful devotion and echo the words of the psalmist:
“Arise, O God, defend your cause; remember the insults that fools hurl at you all day long.” (Psalm 74:22)
And with a final word of triumphant hope:
“Quis ut Deus?” — “Who is like God?”
