The journey

The Lent St. Francis Kept

Mount Alverna, August 1224. Francis of Assisi climbs the mountain to fast forty days in honor of St. Michael the Archangel.

The tradition goes back to the 13th century: St. Bonaventure recounts that Francis, "out of devotion to the angels, fasted forty days from the Assumption of the glorious Virgin." It was during this Lent, near the feast of the Holy Cross, that Francis received the stigmata — the wounds of Christ in his own body. The "Lent of St. Michael" was born there: forty days of prayer, fasting and penance, from August 15 to September 29, the feast of St. Michael, St. Gabriel and St. Raphael.

It is not an official liturgical Lent — it is a devotion of popular piety, of Franciscan roots, which in recent years has mobilized millions of the faithful who wake up at dawn to pray the Rosary. We walk alongside that wave, for the rest of the day: every day at noon — at the hour of the Angelus, when there is a pause — we publish a video with the day's prayer, a meditation and the Way of the Day — a concrete step to Perceive, Decide and Live.

On the first day you choose the grace you will ask for during the forty days and a renunciation to sustain the request. In the final weeks, the journey flows into the traditional novena to St. Michael (September 20–28) and ends on the feast, with the consecration to the Archangel.

The companion book — the forty days complete, with the traditional prayers in full and the source of each one — is free: leave your email below and receive the complete PDF right away, plus your place on the 40-day journey (reminders before it begins, the daily prayer videos and free material along the way).

Prayer to St. Michael the Archangel, composed by Pope Leo XIII (1886)

Saint Michael the Archangel, defend us in battle. Be our protection against the wickedness and snares of the devil.

This is the daily prayer of the journey: added by Leo XIII to the prayers after Mass in 1886, and recommended by St. John Paul II in 1994 — "I ask everyone not to forget it and to recite it to obtain help in the battle against the forces of darkness." In the itinerary you will find the full text and the documented history of each prayer.

Questions

Frequently asked questions

What is St. Michael's Lent?+
It is 40 days of prayer, fasting and penance in honor of St. Michael the Archangel, from August 15 (the Assumption of Our Lady) to September 29 (the feast of the Archangels Michael, Gabriel and Raphael). The tradition goes back to St. Francis of Assisi, who kept this fast and lived it on Mount Alverna — it was during one of these Lents, in 1224, that he received the stigmata.
Is it an official Lent of the Church?+
No — and we say so clearly. St. Michael's Lent is not on the liturgical calendar: it is a devotion of popular piety, of Franciscan tradition documented in the 13th century. What is official is the feast of the Holy Archangels, on September 29. Our itinerary indicates, prayer by prayer, what is traditional text, its source, and what is our own writing.
How do I take part in the 40 days?+
Every day, starting August 15, we publish a video at noon with the full prayer of the day. You pray along with the video (or with the printed itinerary), choose on the first day the grace you will ask for and a renunciation — penance is personal: what is a sacrifice for one may be a relief for another, and only you know what it costs you — and you follow one day at a time, until the consecration on the feast of St. Michael. The tradition does not ask for fasting on Sundays.
Is St. Michael's Lent only for men?+
No. The devotion is open to everyone — men, women, families, prayer groups and parishes. The confusion comes from modern programs built around these forty days that are designed for men only; the tradition itself never was. St. Francis kept this fast on Mount Alverna, and from the 13th century on it was prayed by friars, nuns and lay people alike. Nothing in it depends on your state in life: you choose the grace you will ask for and a renunciation you can actually keep, and you walk the forty days.
What is the prayer of St. Michael's Lent?+
The prayer of the journey is the one composed by Pope Leo XIII in 1886: "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 host, by the power of God, thrust into hell Satan and all evil spirits who prowl about the world seeking the ruin of souls. Amen." It is prayed every day of the forty days. Alongside it, the itinerary carries the traditional consecration to St. Michael and the litany of the Archangel, both in full.
How many days does St. Michael's Lent last?+
Forty days of fasting, in the count St. Francis kept — spread across the forty-six days of the calendar between August 15, the Assumption of Our Lady, and September 29, the feast of the Holy Archangels. The two numbers do not clash: as in the Lent before Easter, the tradition does not ask for fasting on Sundays, so the fast days and the calendar days are not the same count. Our journey publishes a prayer video for every day of the period, and the renunciation you chose rests on the Lord's Day.
Where do the prayers come from?+
All of them have documented provenance: the prayer "Saint Michael the Archangel, defend us in battle" was composed by Pope Leo XIII in 1886 and recommended by St. John Paul II in 1994; the traditional consecration is linked to the shrine of Mount Gargano, in Italy; the litany comes from old devotional manuals; and the final novena follows the structure left by St. Alphonsus Liguori in 1776. The itinerary carries this research printed on its first pages.
Can I pray with my prayer group?+
It was made for that. The prayers are complete and in order, with the source of each one noted, so the coordinator can present the material with confidence. The companion book is free — leave your email above and receive the complete PDF right away to print and share with the group. Prefer bound copies? Paperback and hardcover editions are also available on Amazon, just below.
Is it really free?+
Yes. The videos are public and free on YouTube — the prayers, the meditation and the Way of the Day happen there in full. The companion book is also free: leave your email above and receive the complete PDF right away. If you'd rather have it printed, paperback and hardcover editions are available on Amazon (see below).
