Who Was St. Louis de Montfort?
Louis-Marie Grignion de Montfort (1673–1716) was a French priest, missionary, and mystic whose influence on Catholic Marian devotion has been immense — arguably second only to that of the Apostles themselves in terms of practical impact. He was canonized by Pope Pius XII in 1947, and his spiritual masterwork, True Devotion to Mary, is considered one of the most significant works of Marian theology ever written.
Pope John Paul II was so deeply influenced by de Montfort's spirituality that he adopted the motto Totus Tuus ("Totally Yours") — a phrase drawn directly from Montfort's writings on consecration to Mary.
The Core Idea: Going to Jesus Through Mary
De Montfort's central thesis, developed at length in True Devotion to Mary, is that the surest, shortest, and most perfect path to union with Jesus Christ is through Mary. His reasoning is theological:
- God chose to come into the world through Mary at the Incarnation.
- Mary formed Christ in her womb — she is the one who shapes Christ in souls.
- Therefore, entrusting oneself entirely to Mary's maternal guidance accelerates the formation of Christ within the soul.
This is emphatically not a claim that Mary replaces Christ. De Montfort is explicit: Mary is always a means, never an end. The goal is always deeper union with the Trinity.
What Is Total Consecration?
Total Consecration to Mary (also called "Marian Consecration" or the "Act of Slavery of Love") involves entrusting to Mary one's entire spiritual life — all prayers, merits, good works, and sufferings — so that she may dispose of them according to God's will. The consecrated person asks Mary to be their advocate, guide, and channel of grace.
Practically speaking, it means:
- Performing all spiritual acts in union with Mary and through her intercession
- Asking her to purify one's intentions before presenting them to God
- Seeking her guidance in daily decisions
- Renewing the consecration regularly — daily, if possible
The 33-Day Preparation
De Montfort prescribed a thirty-three day period of preparation before making the Act of Consecration, divided into four phases:
- Days 1–12 — Emptying oneself of the "spirit of the world" through reflection and prayer
- Days 13–19 — Deepening knowledge of oneself (humility and awareness of sin)
- Days 20–26 — Growing in knowledge of the Virgin Mary
- Days 27–33 — Growing in knowledge of Jesus Christ
The consecration itself is traditionally made on a Marian feast day — popular choices include the Feast of the Annunciation (March 25), the Assumption (August 15), and the Immaculate Conception (December 8).
Modern Adaptations
In recent decades, several spiritual writers have developed accessible adaptations of de Montfort's consecration for modern readers. Fr. Michael Gaitley's 33 Days to Morning Glory is among the most widely used, incorporating insights from other Marian saints including St. Maximilian Kolbe, Blessed Mother Teresa, and Pope John Paul II.
Is Consecration to Mary Right for You?
The Church does not require Marian consecration of all Catholics, but it is warmly encouraged as a means of deepening one's faith life. It is particularly suited for those who:
- Desire a more structured and intentional Marian devotion
- Feel called to deepen their relationship with Christ through his Mother
- Seek a framework for integrating prayer and daily life
Beginning with de Montfort's True Devotion to Mary — available in numerous modern translations — is the best first step. The text is challenging but rewarding, and many who begin it report a significant deepening of their interior life.
