Introduction

Saint Louis Marie Grignion de Montfort was born in 1673 in Montfort-la-Cane, in the Brittany region of France, and later became known by the name of his birthplace. He was ordained a priest in Paris in 1700 and gained renown as a preacher, eventually being appointed Apostolic Missionary by Pope Clement XI. In 1715, he founded the Daughters of Wisdom, a congregation dedicated to the education of children and the care of the poor, and in 1713, he established the Missionaries of the Company of Mary for preaching and missionary work. His personal motto was “God Alone.” Saint Louis de Montfort passed away on April 28, 1716, in Saint-Laurent-sur-Sèvre, and was canonized by Pope Pius XII on July 20, 1947. Today, his statue stands in St. Peter’s Basilica.

The life of Saint Louis de Montfort is characterized by his intense missionary activity and deep commitment to the poor. These aspects profoundly shaped his theology, giving it a practical and pastoral nature. His founding of religious congregations reflects his desire to institutionalize and perpetuate his spiritual vision and theological insights for future generations. His experiences as an itinerant missionary provided him with vivid and direct insight into the spiritual needs and practical hardships of the faithful, which in turn deeply influenced the focus and tone of his writings. The unique charisms of the congregations he founded—emphasizing education for the poor and missionary preaching—clearly demonstrate the core priorities of his ministry and theology.

Major Works and Core Theological Themes

Identification and Discussion of Major Works

The principal work of Saint Louis Marie Grignion de Montfort, Treatise on True Devotion to the Blessed Virgin (Traité de la vraie dévotion à la Sainte Vierge), is regarded as the most comprehensive expression of his theology and spirituality. Although written in the early 1700s, it remained virtually unknown until its accidental rediscovery in 1842. Prior to that, even the existence of the manuscript was scarcely known. In this work, Montfort outlines a spiritual path that leads “to Jesus Christ through Mary,” detailing the theological significance of devotion to the Blessed Virgin and providing practical means to live it out. By presenting Marian devotion not as mere external piety but as a profound pathway to union with Jesus Christ, Montfort profoundly influenced the global revival of Marian devotion. His approach was notably ahead of his time, and the delayed discovery of True Devotion can be seen as a providential act within the history of the Church.

The Secret of Mary (Le Secret de Marie) is another important work based on Montfort’s preaching tours across France. In this book, he emphasizes devotion to Mary as the easiest and most secure way to full union with Jesus Christ. Its practical guidance is particularly clear, aiding the faithful in concretely living out their devotion in daily life. Drawing from his direct communication with believers through his preaching, Montfort conveys the essence of the spiritual journey with remarkable simplicity and force. The Secret of Mary effectively blends his pastoral sensitivity with theological depth, continuing to serve as a practical guide for many even today.

The Admirable Secret of the Rosary (Le Secret Admirable du Très Saint Rosaire) explores the spirituality and power of the Rosary in depth. Montfort presents the Rosary not as a simple repetitive prayer but as a profound method for meditating on and experiencing the mysteries of faith. He assigns a specific meditation theme to each bead, enabling the faithful to experience biblical events and the life of Jesus Christ more intimately through prayer. This work offers insights for a wide range of audiences within the Church—priests, religious, and laypeople alike—and strongly emphasizes the interiorization and living practice of the Rosary. Montfort’s educational approach empowers the faithful to engage in deeper and more active prayer through the Rosary.

The Love of Eternal Wisdom (L’Amour de la Sagesse Éternelle) is one of Montfort’s early writings and is considered essential for understanding the entirety of his spirituality. In this book, he highlights Jesus Christ as the Eternal and Incarnate Wisdom of God. Montfort consistently emphasizes that the center of salvation is found in this Eternal Wisdom—Jesus Christ, the Word made flesh. He goes beyond merely devotional reverence to the Blessed Virgin, delving theologically into how God’s love and salvific plan are fulfilled in Christ. This work clearly demonstrates that Montfort’s Marian devotion is not a standalone system but is deeply rooted in Christocentric theology. It lays the theological groundwork for what he would later more fully articulate in True Devotion to the Blessed Virgin, wherein Mary is presented as the most perfect path leading to Eternal Wisdom, that is, Jesus Christ.

Letter to the Friends of the Cross (Lettre aux Amis de la Croix) addresses another major theme of Montfort’s spirituality: the mystery of the Cross. In this letter, he presents the Cross not simply as suffering to be endured, but as the noblest way to attain Eternal Wisdom. For Montfort, the Cross represents the summit of Christ’s love and the very heart of salvation. He insists that every Christian must necessarily pass through the Cross. His phrase “foolish love of the Cross” expresses the attitude of joyfully embracing suffering and sacrifice through faith, even when it seems nonsensical by worldly standards. Through the Cross, Montfort teaches, the believer not only endures hardship but attains deep union with God and true wisdom.

In addition to these major works, Montfort also composed rules for the Missionaries of the Company of Mary and the Daughters of Wisdom, as well as numerous hymns. The rules for his congregations served as practical guidelines for embedding his spiritual ideals within community life. His hymns were designed to make the truths of the faith more accessible and tangible, helping believers to internalize them in daily living. Montfort did not limit the transmission of theological truths to preaching and writing; he sought to concretize faith through song and communal discipline, ensuring that the experience of faith would become a natural part of everyday life.

Doctrine of True Devotion to the Blessed Virgin Mary

A Deep Theological Exploration of Its Meaning and Content

At the heart of Saint Louis Marie de Montfort’s Mariology lies the concept of “total consecration to Jesus through Mary.” He emphasizes that within God’s plan of salvation, Jesus and Mary are inseparably united, and that Mary is the creature who most perfectly resembles Jesus Christ. Consequently, Montfort explains that the most effective path to becoming Christlike and united with Him is through consecration to Mary. He famously stated, “The more the soul is consecrated to her, the more it will be consecrated to Jesus Christ.” This consecration is not merely a devotional act; rather, it involves the complete entrustment of one’s person and possessions to the service of Jesus and Mary, seeing oneself as a “slave of love.”

Montfort understood this consecration as a complete renewal of the baptismal promises. Through it, the faithful can live their baptismal obligations more fully and practice a radical commitment to God. Although the term “slave of love” may seem harsh to modern sensibilities, it must be understood within its theological context, emphasizing total obedience to the will of God and a free, joyful self-offering. Montfort presents Mary’s “fiat”—her complete obedience at the Annunciation—as the model for the faithful in making their consecration.

In explaining the specifics of this consecration, Montfort outlines seven key elements and their effects:
First, a profound recognition of one’s own unworthiness;
Second, participation in Mary’s faith;
Third, the offering of pure love;
Fourth, unlimited trust in God and Mary;
Fifth, receiving the spirit of Mary;
Sixth, transformation into the likeness of Jesus Christ;
And seventh, glorifying Christ more perfectly through one’s daily life.
These elements guide the faithful beyond mere devotional exercises, leading them step by step along a spiritual journey that begins in humility and culminates in union and love with Christ.

Montfort did not view “total consecration” as a mere internal decision. He insisted that this devotion must include both an interior disposition and outward practices. Internally, the faithful are called to entrust themselves continually to Mary and, through her, to Jesus—living and acting “with Mary, in Mary, through Mary, and for Mary.” This attitude reflects a deep spiritual life in which every moment of daily life becomes a path toward God.

Externally, Montfort recommended practices such as joining Marian confraternities, entering religious orders devoted to Mary, promoting knowledge and veneration of her privileges, and practicing charity out of reverence for her. By combining interior devotion with outward action, Montfort sought to ensure that the devotion would not remain a private resolution but would take concrete form within the faith community. This holistic approach highlights the integrated nature of his spirituality, valuing both inner transformation and practical action.

Montfort’s teaching is grounded not in sentimental or purely emotional devotion, but upon a firm theological foundation. He emphasized that Mary was given a unique role within God’s plan of salvation. Especially through her unique cooperation in the Incarnation, her mediating role throughout salvation history, and her profound relationship with the Trinity, Montfort provides the theological basis for this devotion. He believed that God sent His Son into the world through Mary, and that all graces are likewise dispensed through her. Montfort regarded Mary as the spiritual Mother of all Christians and frequently described her as the “mold of God” through whom the Holy Spirit forms Christ within souls.

Montfort’s Mariology, therefore, is not the result of emotional or sentimental piety, but a profound theological reflection on Mary’s place within God’s salvific plan and within the life of the Church. Drawing from scriptural events such as the Annunciation, the Visitation, and Mary’s presence at the foot of the Cross, as well as from the Church’s tradition, Montfort demonstrates that Mary’s mission is not merely auxiliary, but is intrinsically united with the salvation of humanity.

The Triune God in Montfort’s Theology

A Doctrinal Analysis of Saint Louis de Montfort’s Understanding

While Saint Louis de Montfort’s spirituality is characterized by its Christocentric and Marian focus, it is deeply rooted in a profound understanding of the Triune God. Although he received a traditional theological education on the Trinity during his seminary studies, his spirituality transcends mere theoretical analysis. For Montfort, the Trinity was not a subject for philosophical debate but a living mystery of love to be experienced. He perceived the Triune God as the Father, the Son, and the Spirit of Love between them, a love poured into our lives through the Holy Spirit.

Montfort viewed God the Father as the source of self-giving love, eternally begetting the Son. The Son, as Eternal Wisdom, dwells in the bosom of the Father, while the Holy Spirit proceeds as the bond of love between the Father and the Son. For Montfort, this dynamism within the Trinity was not a conceptual abstraction but an experiential confession of the life of God overflowing with love. He especially emphasized how the divine persons of the Trinity are at work within the mystery of Mary, striving through her to bring about the personal encounter between God and humanity.

Montfort’s portrayal of the Trinity as the “family of God” reflects his effort to make this profound mystery more accessible and relatable to ordinary believers. The loving relationship within God and its expansion outward toward humanity constitute the core of his Trinitarian understanding.

The Role of Mary within the Trinity

Saint Louis de Montfort places Mary in a uniquely central position within the life of the Triune God. He describes her as the beloved daughter of God the Father, the true Mother of God the Son, and the faithful spouse and collaborator of the Holy Spirit. He further depicts her as the temple and sanctuary of the Blessed Trinity, the place where God dwells with greater glory than anywhere else in the universe. Montfort firmly believed that no human being had ever penetrated more deeply into the heart of the Triune God than Mary. He emphasized that when believers call upon Mary, they are, in reality, drawing closer to the Triune God.

Montfort clearly articulated the distinct relationship each divine person has with Mary:

The Father chose to send His Son into the world through Mary;
The Son became incarnate within her;
The Holy Spirit, through her free consent, brought forth Jesus Christ within her womb.
Thus, Mary is not merely a conduit for salvation but a living sanctuary actively cooperating with the dynamic love of the Trinity.

Montfort’s perspective portrays Mary not merely as the Mother of Jesus but as someone deeply integrated into the life and love of God. He even described her as a being “entirely relative to God,” meaning that her very existence is defined by her relationship to the divine. In Mary, God’s salvific plan is most perfectly revealed.

Mary’s unique place within the mystery of the Trinity reinforces Montfort’s insistence that she should be a focus of meditation and intercession for the faithful. Through Mary, we can draw closer to the love of the Triune God and become more intimately united with His plan of salvation.

Montfort’s Anthropology: Sin and Grace

His Perspective on Human Nature and the Effects of Original Sin

Saint Louis de Montfort held a very sober view of human nature. He believed that humanity had been almost completely ruined by the Fall and emphasized that original sin had gravely corrupted human existence, filling it with pride and self-centeredness. According to his depiction, human beings are essentially incapable of doing good on their own and are continually weak and unstable. Even after the cleansing of original sin through Baptism, Montfort stressed that remnants of sin, such as concupiscence, still linger within human beings.

Montfort vividly portrayed the fallen state of humanity. He went so far as to say that humans are, by nature, more prideful than a peacock and more abject than a toad, concluding that, by their own strength alone, they merit nothing but divine wrath and eternal condemnation. This stark description was not born of mere pessimism but served to underscore the absolute necessity of divine grace for salvation and spiritual growth. Montfort taught that it is only when a person becomes truly humble and completely dependent on God that the way to salvation is opened.

His view of human nature is deeply connected to the Augustinian tradition, which stresses the profound damage original sin inflicted upon humanity—a perspective that contrasts sharply with more optimistic views that tend to emphasize humanity’s inherent goodness despite the Fall.

His Understanding of Grace

Montfort strongly emphasized that divine grace and assistance are absolutely necessary for any spiritual growth or good action. He believed that no one can attain salvation by their own strength and that all genuine good works are made possible by grace. While affirming that God, in His infinite goodness, continually offers sufficient grace to all, Montfort also acknowledged that this grace is not given to everyone in the same manner or measure.

A particularly important figure in Montfort’s understanding of grace is the Blessed Virgin Mary. He referred to her as the “Mother of Grace,” exalting her as the one who gave the source of all grace—Jesus Christ—to the world. Montfort’s theology consistently affirms that when God the Father sent His Son into the world, He also entrusted all graces to be dispensed through Mary.

Within the supernatural life of grace, Montfort regarded God as our Father and Mary as our Mother. He taught that in order for the faithful to be truly filled with grace and truth, they must be formed within Mary, and through her, approach the grace of Jesus Christ. For Montfort, devotion to Mary is a most excellent means of attaining the greater glory of God. He firmly believed that approaching Christ through Mary is the safest, easiest, shortest, and most perfect way to receive divine help.

Montfort’s Marian-centered understanding of grace extends beyond mere devotion; it is deeply rooted in his overall soteriology and theology of grace. His view that grace is mediated to humanity through Mary is intimately connected with his Christocentrism, not diminishing the theological truth that all grace ultimately comes from Jesus Christ but rather highlighting it all the more profoundly.

The Priesthood in Montfort’s Thought and Spirituality

Saint Louis de Montfort’s Understanding of the Priesthood

From an early age, Saint Louis de Montfort felt a strong vocation to the priesthood, which he understood as a ministry of total surrender to God and a life lived in poverty. He envisioned priests as being free from worldly possessions and honors, open solely to the inspirations of God. For Montfort, the priesthood was not merely an ecclesiastical status but a mission of fully entrusting oneself to the will and providence of God, proclaiming the Gospel, and working for the salvation of souls.

Montfort particularly felt called to bridge the gap between academic theology and the lived experiences of the laity, responding to the Church’s spiritual needs through popular missionary preaching. To realize this vision, he founded the Missionaries of the Company of Mary, dedicating himself to the proclamation of the Gospel especially among the poor and marginalized. His understanding of the priesthood emphasized radical dependence on God, missionary service among the poor, celebrating the Eucharist as the center of priestly life, and prioritizing the proclamation of the Word of God in pastoral ministry.

He sought to establish a community of poor, itinerant apostles, detached from worldly comforts and social status. His personal experiences of poverty and hardship reinforced his conviction that the priesthood is not about seeking material comfort but about giving oneself entirely for the salvation of souls.

His Priestly Vocation and the Founding of Religious Institutes

Inspired by the life of Father Julien Bellier, an itinerant missionary priest, Montfort resolved to devote himself to missionary preaching among the poor. Under the guidance of various priests, he cultivated a deep devotion to the Blessed Virgin Mary, which became the cornerstone of both his priestly life and missionary activity. His fervor and vocation were officially recognized by Pope Clement XI, who appointed him as an Apostolic Missionary.

Montfort established the Daughters of Wisdom to serve the education of children and the care of the impoverished, and he founded the Missionaries of the Company of Mary to sustain the work of popular missions. Although his ministry often encountered misunderstanding and opposition, he never gave up. Rather, such trials strengthened his vocation and intensified his desire to bring the Gospel to the poor and the marginalized.

The founding of his religious communities was not merely an act of organizational establishment but an expression of his lifelong commitment to Gospel poverty, trust in divine providence, and total surrender to God within a communal framework. His perseverance and patience testify that his vocation was not a mere personal enthusiasm but a firm response to a divine calling.

Comparison with the Catholic Church’s Teaching

The Catholic Church teaches that the priesthood is a ministry at the service of the common priesthood of the faithful. Priests are charged with proclaiming the Gospel, administering the sacraments, and leading the people of God. Missionary activity is considered one of the essential missions of the Church, and some priests are specially called to this apostolic task. Montfort’s emphasis on the essential nature of the priesthood aligns closely with this teaching of the Church.

In particular, Montfort emphasized that priests must renounce worldly possessions and honors, remaining completely open to divine inspiration. This resonates deeply with the Church’s evangelical counsels, which call priests to witness to the Gospel through poverty and humility. Furthermore, Montfort centered the Eucharist at the heart of priestly life and prioritized the proclamation of the Word of God in ministry—both of which are integral to the modern Catholic understanding of the priesthood.

Montfort’s spirituality also aligns with the traditions of the French School of Spirituality, which places special emphasis on the mystery of the Incarnation and the role of the Blessed Virgin Mary. He regarded devotion to Mary as a vital element of the priestly life, believing that through Mary, the faithful could draw closer to Christ and grow in holiness. This perspective is fundamentally consistent with the Marian devotion encouraged by the Catholic Church.

When examining the documents of the Second Vatican Council—especially the Decree on the Ministry and Life of Priests (Presbyterorum Ordinis)—and the Catechism of the Catholic Church, it becomes evident that Montfort’s vision of the priesthood is in full harmony with contemporary Church teaching. His emphasis on sanctification and evangelization through Marian devotion within the common priesthood remains a meaningful and practical model for priestly spirituality even today.

The Place of Montfort’s Theology within Catholic Theology and Its Influences

Reception and Status of His Theology within the Church

Saint Louis Marie Grignion de Montfort is recognized as a figure of significant importance within Catholic theology, particularly in the field of Mariology. His principal writings are regarded as classic works of Catholic spirituality and have profoundly influenced numerous popes. In particular, Pope John Paul II highly esteemed him as a “master of Marian spirituality,” and explicitly acknowledged that his own pastoral motto, Totus Tuus (“Totally Yours”), was directly inspired by the teachings of Saint Louis de Montfort.

Montfort’s theology transcends mere personal devotion to Mary; it is deeply rooted in the central mysteries of Christian faith—the Trinity and the Incarnation of the Word. His spirituality illuminates Mary’s role within these fundamental doctrines, guiding the faithful toward a more perfect journey to Christ.

Even after the Second Vatican Council, the Church has continued to recognize the essential validity of Montfort’s teachings, encouraging further study and application of his insights. The consistent support of various popes, including Pope John Paul II, clearly demonstrates that Montfort’s spiritual vision and the devotion he proposed are fundamentally harmonious with Catholic doctrine. The fact that his writings have remained beloved and widely studied over the centuries is a testament to the profound theological grounding and spiritual vitality of his thought, rather than to mere historical or cultural circumstance.

Relationship with Other Saints and Theological Schools

Montfort’s theology and spirituality were not developed in isolation but were deeply shaped by the rich tradition of the seventeenth-century French School of Spirituality. This school emphasized the centrality of the Incarnation and fostered a profound devotion to the Blessed Virgin Mary. Figures such as Cardinal Pierre de Bérulle, Jean-Jacques Olier, and Saint John Eudes represent this tradition, and Montfort’s Christocentric and Marian focus naturally aligns with their teachings.

Particularly during his formation at the Sulpician seminary, Montfort was further immersed in a theological tradition that emphasized the mysteries of the Incarnation and Mary’s role within salvation history. This background significantly influenced his emphasis on Mary’s place in the divine economy of salvation, as evidenced throughout his writings.

Moreover, Montfort was affiliated with the Third Order of Saint Dominic, suggesting a close connection with the Dominican tradition’s strong Marian devotion. His Mariology resonates with the Dominican emphasis on the Rosary, the mystery of the Incarnation, and the salvific role of Mary.

Montfort frequently cited and referenced early saints and theologians renowned for their Marian devotion, including Saint Augustine, Saint Bernard of Clairvaux, Saint Bonaventure, and Saint Bernardine of Siena. By situating his teachings within this ancient tradition, Montfort sought to ensure consistency with the insights of the early Church Fathers and to embed his theology firmly within the historical development of Marian devotion.

Thus, Montfort’s theology inherits and enriches the Catholic spiritual and theological tradition that highlights Mary’s unique role in the mysteries of the Incarnation and salvation. Through his writings, we can see the living presence of the French School and Dominican spirituality. Furthermore, the continuity between the Marian insights of the early saints and Montfort’s systematic teachings demonstrates that his theology is not merely an expression of personal piety but is deeply rooted in the living faith tradition of the Church.

The Impact and Significance of Montfort’s Theology in Contemporary Catholic Faith and Theology

Influence on Modern Catholic Spirituality, Particularly Marian Devotion

Saint Louis de Montfort’s doctrine of “total consecration to Jesus through Mary” continues to exert profound influence within the contemporary Catholic Church. His principal work, True Devotion to the Blessed Virgin, remains widely read, studied, and practiced among laypeople, religious communities, and Marian movements throughout the world. Montfort’s emphasis on the Rosary has also significantly contributed to its establishment as a core element of Catholic prayer life today. He presented the Rosary not as mere repetitive prayer, but as a powerful spiritual weapon for deepening one’s faith through the meditation on the mysteries of Christ’s life.

Many Catholics have embraced Montfort’s spirituality as an effective means of living out their baptismal promises more faithfully. His devotion to Mary leads believers into deeper union with Christ and fosters a life of concrete love for God and neighbor. The ongoing relevance of Montfort’s influence shows that his teaching on Marian devotion deeply resonates with the spiritual aspirations of modern believers, offering a clear path to sanctity through the maternal guidance of Mary.

The continued popularity and study of his writings across generations suggest that Montfort’s spiritual insights still offer powerful and relevant answers to the deepest human longing for union with God and the search for meaning in life.

Relevance to Modern Theological Discourse and His Influence on Pope John Paul II

Montfort’s theology maintains significant relevance within contemporary theological discourse. Particularly noteworthy is how he proposed a balanced Marian devotion deeply anchored within a Christocentric framework. In an age when Marian devotion can sometimes be misunderstood or marginalized, Montfort’s teachings affirm both the legitimacy and centrality of Marian devotion within the broader mystery of salvation. He carefully avoided any suggestion that Mary is an independent agent of salvation, while firmly upholding her unique and vital role within God’s salvific plan.

Montfort’s foundational principle, “God Alone,” stands at the heart of all his spiritual practices, providing a clear theological basis for prioritizing God above all else in the spiritual life. This emphasis remains especially pertinent today, calling Catholics to retain a firm center of faith amidst the challenges of secularism and relativism.

One of the most striking testimonies to Montfort’s enduring impact on the modern Catholic Church is his influence on Pope John Paul II. As a young seminarian, Karol Wojtyła (the future John Paul II) experienced a profound spiritual transformation after reading True Devotion to the Blessed Virgin. He adopted Montfort’s teachings as the foundation for his personal life, priesthood, and entire papacy, symbolically expressed through his personal motto, Totus Tuus (“Totally Yours”).

Pope John Paul II frequently referenced Montfort in his encyclicals and speeches, recognizing him as a key witness of Marian spirituality. In particular, his encyclical Redemptoris Mater (“Mother of the Redeemer”) draws upon Montfort’s teaching to reaffirm the importance of Marian consecration in living out the promises of baptism. Thus, Montfort’s theology remains not merely a legacy of the past but a living spiritual source that continues to inspire and sustain the Catholic Church today.

The Official Position of the Catholic Church

Presentation and Analysis of Official Church Documents and Papal Statements

The Catholic Church has consistently held Saint Louis Marie Grignion de Montfort and his theological contributions in high esteem. Numerous popes have explicitly recognized and praised his holiness, especially his profound devotion to the Blessed Virgin Mary.

Pope Pius IX clearly affirmed the authority of Montfort’s teachings by declaring his Marian devotion as “the best and most acceptable form” of devotion. Pope Leo XIII granted a plenary indulgence to those who practiced Montfort’s act of total consecration, further endorsing his spirituality. Pope Pius X sincerely recommended True Devotion to the Blessed Virgin, affirming the profound depth of Montfort’s spirituality. In 1947, Pope Pius XII officially canonized Saint Louis de Montfort, thereby confirming both his sanctity and the orthodoxy of his teachings at the level of the universal Church.

Pope Paul VI later emphasized the essential connection between devotion to Mary and devotion to Christ, affirming that Montfort’s approach was fully aligned with the core of Catholic doctrine. Particularly significant is Pope John Paul II, who, in a letter to the Montfortian Family, praised True Devotion to the Blessed Virgin as a “classic of Marian spirituality” and personally testified to the profound influence the book had on his own life.

Pope John Paul II also made it clear that Montfort’s Mariology is deeply rooted in the mysteries of the Trinity and the Incarnation, and remains fully valid even in light of the teachings of the Second Vatican Council. In his encyclical Redemptoris Mater, he explicitly cited and praised Montfort’s spirituality, acknowledging its effectiveness in helping Christians to live out their baptismal commitments more faithfully.

The personal motto of Pope John Paul II as bishop and pope, Totus Tuus (“Totally Yours”), was directly inspired by Saint Louis de Montfort, symbolizing the deep respect and strong support the Church extends to his teachings.

The consistent endorsement by successive popes over the centuries, along with the personal devotion of key modern Church figures, clearly demonstrates that Montfort’s theology—particularly his teaching on Marian devotion—has received formal and substantial approval from the Catholic Church. Through indulgences, letters, and encyclicals, the Church has expressed profound gratitude and high esteem for Montfort’s spiritual and theological contributions.
