Saint Margaret Mary Alacoque was born on July 22, 1647, in Lhautecour, France. From her earliest years, she displayed a deep love for prayer and a strong devotion to the Blessed Sacrament. After recovering from a serious illness through the intercession of the Blessed Virgin Mary, she made a vow to dedicate her life entirely to God.
At the age of twenty-four, she entered the Visitation Convent at Paray-le-Monial, founded by Saint Jane Frances de Chantal and Saint Francis de Sales. There, her hidden life of prayer and humility became the foundation for one of the Church’s most profound devotions—the devotion to the Sacred Heart of Jesus.
Visions of the Sacred Heart
Between 1673 and 1675, Saint Margaret Mary received a series of extraordinary revelations from Christ. In these visions, Jesus revealed His Sacred Heart, burning with love for humanity and wounded by indifference and sin. He told her:
“Behold this Heart which has so loved men, that It has spared nothing, even to exhausting and consuming Itself, to testify Its love.”
The Lord asked her to spread devotion to His Heart, to promote frequent Communion, especially on First Fridays, and to encourage a Holy Hour of reparation every Thursday night. These requests became the foundation of the Sacred Heart devotion, now a central part of Catholic spirituality.

Trials and Perseverance
At first, her fellow nuns doubted her visions and accused her of delusion. Yet Saint Margaret Mary remained patient and obedient. Her spiritual director, Saint Claude de la Colombière, a Jesuit priest, recognized the authenticity of her experiences and became her steadfast supporter.
With his guidance, her message gradually gained acceptance. Her humility, suffering, and unwavering faith transformed skepticism into belief. Over time, devotion to the Sacred Heart spread throughout France and the world, bringing renewal and consolation to countless souls.
A Heart United with Christ
Saint Margaret Mary’s life was marked by deep interior union with Christ. She offered every joy and suffering as an act of reparation for sins against His Heart. Her spirituality emphasized love, repentance, and total surrender to God’s will.
In her final years, she often repeated: “The Sacred Heart is an inexhaustible fountain of mercy and grace.” She died on October 17, 1690, at the age of forty-three, after receiving Holy Communion and whispering, “I need nothing but God, and to lose myself in the Heart of Jesus.”
Canonization and Legacy
The Church formally recognized the truth of her revelations through centuries of devotion and miraculous fruits. Saint Margaret Mary Alacoque was canonized in 1920 by Pope Benedict XV. Her feast day is celebrated on October 16.
Through her, Christ renewed His call for love, reparation, and mercy—a message that continues to inspire the faithful. The image of the Sacred Heart of Jesus, often shown aflame with divine love, remains one of the most beloved symbols in Catholic devotion today.
Conclusion
Saint Margaret Mary Alacoque’s life reminds us that divine love is not abstract but deeply personal. The Sacred Heart calls each soul to respond with love, repentance, and trust. Her mission endures in every act of charity and every prayer offered before the image of Christ’s Heart—a symbol of mercy without measure.
