Total Consecration to Jesus Through Mary

Devotions

St. Louis-Marie de Montfort’s classic method for consecrating one’s whole life to Christ through Mary’s hands.

Total Consecration to Jesus Through Mary is the specific method of Marian consecration developed by St. Louis-Marie Grignion de Montfort, a French missionary and spiritual writer of the seventeenth and eighteenth centuries. It involves a period of preparatory prayer, traditionally 33 days, followed by a formal act entrusting one’s whole self — prayers, works, and merits — to Christ through Mary. It later shaped Pope St. John Paul II, who took his papal motto, Totus Tuus, directly from Montfort’s formula.

What Is This Devotion?

Total Consecration to Jesus Through Mary is a specific, structured method of Marian consecration set out by St. Louis-Marie de Montfort in his book known in English as True Devotion to Mary. It asks the person making it to give Christ everything — every prayer, work, joy, and suffering — by placing it first in Mary’s hands, trusting her to purify it and offer it to her Son. Montfort described this self-gift in the striking, paradoxical language of his era as a ‘holy slavery of love’: not literal servitude, but a deliberately total and freely chosen surrender, meant to counter the modern instinct to hold something back for oneself.

Origin and History

St. Louis-Marie Grignion de Montfort (1673–1716) was a French missionary priest whose preaching and writing centered on radical devotion to Christ through Mary. His manuscript on total consecration was not published in his own lifetime; it was rediscovered decades after his death and first printed in the 1840s, more than a century later, after which it spread widely and shaped Marian devotion across the Catholic world. Montfort himself was canonized by Pope Pius XII in 1947. In the twentieth century, St. Maximilian Kolbe drew heavily on Montfort’s spirituality in founding the Militia Immaculatae, and Pope St. John Paul II adopted the motto ‘Totus Tuus’ (‘totally yours’) directly from Montfort’s consecration formula as his own papal motto, crediting Montfort’s writing as a major influence on his own Marian spirituality.

Catholic Theology

Montfort’s method rests on the same basic theology as Marian consecration generally: Mary’s closeness to Christ makes her intercession a fitting and fruitful path toward him, without in any way replacing his unique mediation (1 Timothy 2:5). What distinguishes Montfort’s specific approach is its emphasis on totality and structure — nothing held back, and a defined process for getting there — along with his teaching that Mary shapes and perfects the gift before it reaches her Son, much as she once formed his human nature in her womb.

How to Practice It

Undertake a preparatory period, traditionally 33 days, broken into shorter stages of prayer and reflection — commonly moving through detachment from worldly attachments, then knowledge of self, then knowledge of Mary, then knowledge of Christ.
Continue ordinary prayer, Mass, and sacramental life throughout the preparation; Montfort’s method is meant to deepen an existing Catholic life, not substitute for it.
Make the formal act of consecration on a chosen day, traditionally a Marian feast such as the Annunciation, the Immaculate Conception, or the Assumption.
Renew the consecration regularly afterward — many who make it renew it annually on the same date.

Associated Prayers

When It’s Observed

There is no single fixed date; those making the consecration choose their own start date so that the roughly month-long preparation ends on a Marian feast day of their choosing, most commonly the Immaculate Conception, the Annunciation, or the Assumption.

Church Status

Montfort’s method is a well-established and widely practiced form of Marian devotion, strengthened in the Church’s eyes by his own canonization and by its adoption by figures including Kolbe and John Paul II. It remains, like all Marian consecration, an optional devotional practice rather than an obligation, and is meant to be lived in a way that leads toward Christ and the sacraments rather than standing apart from them.

Private Revelation

Montfort’s Total Consecration does not rest on any private revelation. Montfort was a preacher and spiritual writer working from Scripture and the theological tradition of his time, not someone reporting a personal apparition or vision — a point worth making clearly, since this devotion is sometimes loosely associated in people’s minds with apparition-based Marian devotions elsewhere on this site, such as those connected with Fatima or Lourdes, with which it has no historical connection.

Common Misconceptions

“Calling it ‘holy slavery’ means Montfort taught something degrading.”

Montfort used the language of ‘slavery’ deliberately and paradoxically, to express a total, freely chosen gift of self in love — not literal servitude or a loss of dignity; many modern presentations of his method use softer language, such as total self-giving, to convey the same idea.

“This consecration replaces or downgrades ordinary Catholic practice, like Mass and confession.”

It is meant to deepen an already-practicing Catholic life, not substitute for it — Montfort’s own writing assumes ongoing sacramental participation throughout the preparation and after the act of consecration.

Frequently Asked Questions

Who was St. Louis-Marie de Montfort?

A French missionary priest (1673–1716) known for his preaching on Marian devotion, canonized by Pope Pius XII in 1947; his feast day is April 28.

Why does the preparation take 33 days?

The number is traditionally connected to the number of years many hold that Christ lived on earth, symbolizing a complete, unhurried preparation rather than a fixed doctrinal requirement.

Where did Pope John Paul II’s motto ‘Totus Tuus’ come from?

He drew it directly from Montfort’s consecration formula, crediting Montfort’s writing on total Marian consecration as a significant influence on his own spirituality.

Is this the same as generally consecrating oneself to Mary?

It is one specific, structured method for doing so; see our page on Consecration to the Blessed Virgin Mary for the broader practice and its other forms.
