St. Louis-Marie de Montfort’s 33-Days
Total Consecration to Jesus through Mary


St. Louis-Marie Grignion De Montfort (1673-1716) remains one of the greatest apostles of Marian devotion the world has ever known. As a young priest, De Montfort dedicated himself to preaching to the people. This highly gifted orator's language was simple but full of divine love, much as you will find in True Devotion to Mary. De Montfort s whole life was marked by constant prayer, love for the poor and holy joy in humiliations and persecutions. De Montfort was canonized by Pius XII in 1947.

His 33-Day Consecration to Jesus through Mary, is known as “Total Consecration,” “True Devotion,” or “Holy Slavery,” is a smooth, short, perfect and sure way of attaining union with our Lord, in which Christian perfection consists.

(a) This devotion is a smooth way. It is the path which Jesus Christ opened up in coming to us and in which there is no obstruction to prevent us reaching him. It is quite true that we can attain to divine union by other roads, but these involve many more crosses and exceptional setbacks and many difficulties that we cannot easily overcome.

(b) This devotion is a short way to discover Jesus, either because it is a road we do not wander from, or because, as we have just said, we walk along this road with greater ease and joy, and consequently with greater speed. We advance more in a brief period of submission to Mary and dependence on her than in whole years of self-will and self-reliance.

(c) This devotion is a perfect way to reach our Lord and be united to him, for Mary is the most perfect and the most holy of all creatures, and Jesus, who came to us in a perfect manner, chose no other road for his great and wonderful journey. The Most High, the Incomprehensible One, the Inaccessible One, He who is, deigned to come down to us poor earthly creatures who are nothing at all. How was this done? The Most High God came down to us in a perfect way through the humble Virgin Mary, without losing anything of his divinity or holiness. It is likewise through Mary that we poor creatures must ascend to almighty God in a perfect manner without having anything to fear.

(d) This devotion to our Lady is a sure way to go to Jesus and to acquire holiness through union with him. Indeed it could not be condemned without overthrowing the foundations of Christianity. It is obvious then that this devotion is not new. If it is not commonly practised, the reason is that it is too sublime to be appreciated and undertaken by everyone. This devotion is a safe means of going to Jesus Christ, because it is Mary’s role to lead us safely to her Son.


How to Make Your Consecration

Choose the date of a Marian Feast on which to make the consecration. Whichever Feast you choose will determine the date to begin a 33-day period of spiritual preparation, i.e., you follow spiritual exercises for 33 days, and the next day - Day 34 will be the Marian Feast on which you consecrate yourself.

The Feast of the Annunciation is the Feast that St. Louis de Montfort recommends most of all as it is this Feast that commemorates God Himself taking on flesh and, thereby, subjecting even Himself to trust in and dependency on Our Lady.


For the 33-day period of exercises, St. Louis-Marie breaks these days into sections of days, each section having its own prayers, and each particular day having its own brief readings with which to fill the mind for that day (the readings come from Sacred Scripture, “The Imitation of Christ,” and “True Devotion to the Blessed Virgin Mary”). Don’t just read the readings, internalize them; don’t let your lips just mouth the prayers, truly pray them.

~ First comes a 12-day preparation period that consists of emptying oneself of the spirit of the world in penance and mortification. For those 12 days, the Veni Creator is prayed, the Ave Maris Stella, the Magnificat, and the Glory Be. Then follows 3 weeks, each week having a specific focus.

~ The first week focuses on offering up our prayers and devotions for the purpose of coming to understand ourselves and our sins; humility is the key, and the prayers the Litany of the Holy Ghost, the Litany of Loreto, and the Ave Maris Stella help us.

~ During the second week, we ask the Holy Ghost to help us better understand the Blessed Virgin; the Litany of the Holy Ghost is prayed, the Litany of Loreto, the Ave Maris Stella, the prayer to Mary by St. Louis-Marie, and 5 decades of the Holy Rosary each day for assistance.

~ During the third week, we seek to better understand Christ through meditation and the Litany of the Holy Ghost, the Ave Maris Stella, and the Litany of the Holy Name of Jesus, Montfort’s prayer to Jesus, and the prayer O Jesus Living in Mary.

At the end of three weeks, we should go to confession and Holy Communion with the intention of giving ourselves to Jesus Christ in the quality of slaves of love, by the hands of Mary. After Communion, we should recite the consecration prayer—we ought to write it, or have it written, and sign it the same day the consecration is made.
It would be well that on this day, we should pay some tribute to Jesus Christ and our Blessed Lady, either as a penance for our past unfaithfulness to the vows of Baptism, or as a testimony of dependence on the dominion of Jesus and Mary. This tribute should be one in accordance with your fervor, such as a fast, a mortification or an alms, or a candle. If but a pin is given in homage, and given with a good heart, it will be enough for Jesus, Who loves only the good will. 

Once a year at least, and on the same day, we should renew this consecration, observing the same practices during the three weeks.

The 34th day is the day of consecration.

All daily readings and prayers are here below with on-site links.

12 Day Preparation: Renouncing the Spirit of the World
Examine your conscience, pray, practice renouncement of your own will; mortification, purity of heart. This purity is the indispensable condition for contemplating God in heaven, to see Him on earth and to know Him by the light of faith.


The first part of the preparation should be employed in casting off the spirit of the world which is contrary to that of Jesus Christ. The spirit of the world consists essentially in denial of the supreme domination of God; a denial which is manifested in practice by sin and disobedience; thus it is principally opposed to the spirit of Christ, which is also that of Mary.


It manifests itself by the concupiscence of the flesh, by the concupiscence of the eyes and by the pride of life. By disobedience to God’s laws and the abuse of created things. Its works are: sin in all forms, then all else by which the devil leads to sin; works which bring error and darkness to the mind, and seduction and corruption to the will. Its pomps are the splendor and the charms employed by the devil to render sin alluring in persons, places and things.

Day 12 - March 17th: Consecration To Mary Readings and Prayers Day 12 of 33

First Week: Knowledge of Self
Prayers, examens, reflection, acts of renouncement of our own will, of contrition for our sins, of contempt of self—all performed at the feet of Mary, for it is from her that we hope for light to know ourselves.


It is near her, that we shall be able to measure the abyss of our miseries without despairing. We should employ all our pious actions in asking for a knowledge of ourselves and contrition of our sins: and we should do this in a spirit of piety.


During this period, we shall consider not so much the opposition that exists between the spirit of Jesus and ours, as the miserable and humiliating state to which our sins have reduced us. Moreover, the True Devotion being an easy, short, sure and perfect way to arrive at that union with our Lord, which is Christlike perfection, we shall enter seriously upon this way, strongly convinced of our misery and helplessness. But, how attain this without a knowledge of ourselves?

Second Week: Knowledge of Mary
Acts of love, pious affections for the Blessed Virgin, imitation of her virtues, especially her profound humility, her lively faith, her blind obedience, her continual mental prayer, her mortification in all things, her ardent charity, her heroic patience, her angelic sweetness and her divine wisdom: “these being,” as St. Louis De Montfort says, “the ten principal virtues of the Blessed Virgin.”


We must unite ourselves to Jesus through Mary—this is the characteristic of our devotion; therefore Saint Louis De Montfort asks that we employ ourselves in acquiring a knowledge of the Blessed Virgin. Mary is our sovereign and our mediatrix, our Mother and our Mistress.


Let us then endeavor to know the effects of this royalty, of this mediation, and of this maternity, as well as the grandeurs and prerogatives which are the foundation or consequences thereof. Our Blessed Mother is also perfect—a mold wherein we are able to be molded in order to make her intentions and dispositions ours. This we cannot achieve without studying the interior life of Mary, namely, her virtues, her sentiments, her actions, her participation in the mysteries of Christ and her union with Him.

True Devotion to Mary Nos. 60-67, 183, 212, 226-265


Acts of love of God, thanksgiving for the blessings of Jesus, contrition and resolution During this period we shall apply ourselves to the study of Jesus Christ. What is to be studied in Jesus Christ?


First: The Man-God, His grace and glory; then His rights to sovereign dominion over us; since, having renounced Satan and the world, we have taken Jesus Christ as our Lord. Second: His interior life; namely, the virtues and the acts of His Sacred Heart; His association with Mary in the mysteries of the Annunciation and Incarnation. During His infancy and hidden life at the feast of Cana and on Calvary. . . .

Day 34: Day of Consecration
On the day of consecration, either fast, give alms, or offer a votive candle for the good of another (or all of the above); do some spiritual penance and approach consecration in the spirit of mortification. 


Now go to Confession (or, if that is not possible, go during the 8 days prior) and then receive Communion with the intention of giving yourself to Jesus, as a slave of love, by the hands of Mary. Try to receive Communion per the method described in the Supplement of the book, “True Devotion to the Blessed Virgin Mary” above.


Now pray the words of the consecration. Copy them and have them with you at church, read them after the Mass (in front of the tabernacle would be nice), and sign your copy of the Act of Consecration. 


The words of consecration are:


O Eternal and incarnate Wisdom! O sweetest and most adorable Jesus! True God and true man, only Son of the Eternal Father, and of Mary, always virgin! I adore Thee profoundly in the bosom and splendors of Thy Father during eternity; and I adore Thee also in the virginal bosom of Mary, Thy most worthy Mother, in the time of Thine incarnation.


I give Thee thanks for that Thou hast annihilated Thyself, taking the form of a slave in order to rescue me from the cruel slavery of the devil. I praise and glorify Thee for that Thou hast been pleased to submit Thyself to Mary, Thy holy Mother, in all things, in order to make me Thy faithful slave through her. But, alas! Ungrateful and faithless as I have been, I have not kept the promises which I made so solemnly to Thee in my Baptism; I have not fulfilled my obligations; I do not deserve to be called Thy child, nor yet Thy slave; and as there is nothing in me which does not merit Thine anger and Thy repulse, I dare not come by myself before Thy most holy and august Majesty. It is on this account that I have recourse to the intercession of Thy most holy Mother, whom Thou hast given me for a mediatrix with Thee. It is through her that I hope to obtain of Thee contrition, the pardon of my sins, and the acquisition and preservation of wisdom.


Hail, then, O immaculate Mary, living tabernacle of the Divinity, where the Eternal Wisdom willed to be hidden and to be adored by angels and by men! Hail, O Queen of Heaven and earth, to whose empire everything is subject which is under God. Hail, O sure refuge of sinners, whose mercy fails no one. Hear the desires which I have of the Divine Wisdom; and for that end receive the vows and offerings which in my lowliness I present to thee.


I, N_____, a faithless sinner, renew and ratify today in thy hands the vows of my Baptism; I renounce forever Satan, his pomps and works; and I give myself entirely to Jesus Christ, the Incarnate Wisdom, to carry my cross after Him all the days of my life, and to be more faithful to Him than I have ever been before. In the presence of all the heavenly court I choose thee this day for my Mother and Mistress. I deliver and consecrate to thee, as thy slave, my body and soul, my goods, both interior and exterior, and even the value of all my good actions, past, present and future; leaving to thee the entire and full right of disposing of me, and all that belongs to me, without exception, according to thy good pleasure, for the greater glory of God in time and in eternity.


Receive, O benignant Virgin, this little offering of my slavery, in honor of, and in union with, that subjection which the Eternal Wisdom deigned to have to thy maternity; in homage to the power which both of you have over this poor sinner, and in thanksgiving for the privileges with which the Holy Trinity has favored thee. I declare that I wish henceforth, as thy true slave, to seek thy honor and to obey thee in all things.


O admirable Mother, present me to thy dear Son as His eternal slave, so that as He has redeemed me by thee, by thee He may receive me! O Mother of mercy, grant me the grace to obtain the true Wisdom of God; and for that end receive me among those whom thou lovest and teachest, whom thou leadest, nourishest and protectest as thy children and thy slaves.


O faithful Virgin, make me in all things so perfect a disciple, imitator and slave of the Incarnate Wisdom, Jesus Christ thy Son, that I may attain, by thine intercession and by thine example, to the fullness of His age on earth and of His glory in Heaven. Amen.

After Consecration
Once you have consecrated yourself to Jesus through Mary, live that consecration. St. Louis-Marie de Montfort recommended the following:


~ Keep praying to develop a “great contempt” for the spirit of this world.


~ Maintain a special devotion to the Mystery of the Incarnation (e.g., through meditation; spiritual reading; focusing on Feasts centering around the Incarnation, such as the Annunciation and the Nativity, etc.)


~ Frequently recite the Ave, Rosary, and the Magnificat.


~ Recite, every day if it is not inconvenient, the "Little Crown of the Blessed Virgin Mary' — a series of Paters, Aves, and Glorias — one Ave for each star in the Virgin’s Crown. St. Louis has a special way of praying the Little Crown, which is recommended.


~ Do everything through, with, in and for Mary for the sake of Jesus, with the prayer, “I am all thine Immaculate One, with all that I have: in time and in eternity” in your heart and on your lips.


~ Associate yourself with Mary in a special way before, during, and after Communion (see Supplement of the book, “True Devotion to the Blessed Virgin Mary” above).


~ Wear a little iron chain (around the neck, arm, waist, or ankle) as an outward sign and reminder of holy slavery. This practice is optional, but very recommended by St. Louis. The appearance of this chain is not further specified, but they can be purchased (search for “consecration chain”) or homemade.


~ Renew the consecration once a year on the same date chosen above, and by following the same 33-day period of exercises. If desired, also renew the consecration monthly with the prayer, “I am all thine and all I have is thine, O dear Jesus, through Mary, Thy holy Mother.”


~ Optional: Join the Confraternity of Mary, Queen of All Hearts.
