St. Margaret Mary Alacoque

Margaret Mary Alacoque was born on July 22, 1647, in Lhautecour, a village in the Burgundy region of eastern France, though her family later moved to the nearby town of Paray-le-Monial. She was the fifth of seven children of Claude Alacoque, a royal notary, and Philiberte Lamyn. Margaret Mary's childhood was marked by illness and a deep early piety, reportedly shaped by a conversion experience at the age of nine or ten when she consecrated herself to the Blessed Virgin Mary during a period of suffering with rheumatic fever. She is said to have received a vision of Christ in which He reproached her for her indifference, and that this experience would foreshadow the mystical encounters of her later life. Her father died around 1659, after which the family experienced financial difficulties that delayed her religious vocation.

In 1671, at the age of about 24, Margaret Mary entered the Visitation convent at Paray-le-Monial, a community known for its gentleness of rule and its emphasis on the interior life. She was professed in 1672, taking the religious name Margaret Mary, and she served for many years as an infirmarian, caring for the sick sisters in the community. Her life in the convent was marked by periods of severe spiritual trial and the intense suffering she called her 'great trial,' during which she felt abandoned by God. She also reported mystical phenomena including a vision of Christ asking for her heart, exchanging it for His own. She was supported during this period by the Jesuit priest Saint Claude de la Colombière, who served as her spiritual director from 1675 until his departure for England, and whose discernment helped validate her experiences. Beginning in 1673 and continuing into 1675, Margaret Mary reported four major apparitions of Jesus Christ in which He revealed the symbolism of His Sacred Heart and made specific requests of the faithful and of the Church.

In these visions, Christ is said to have asked for the establishment of a feast day honoring His Sacred Heart, for Holy Communion on the First Friday of each month, for the practice of the Holy Hour, and for a special devotion of reparation. The Great Revelation, traditionally dated to June 16, 1675, included the words attributed to the Sacred Heart: 'Behold this Heart which has loved men so much.' Margaret Mary faced significant opposition within her own community, where her superiors and some sisters regarded her claims with suspicion; she was even treated harshly at times. She persisted in her mission, later recording her mystical experiences and corresponding with those who sought her spiritual counsel, including members of the French royal family and other religious communities. Although the public establishment of the Feast of the Sacred Heart did not occur in her lifetime, devotion to the Sacred Heart grew steadily through the efforts of her Jesuit spiritual sons, including Saint Claude de la Colombière, and others who promoted her writings.

Margaret Mary Alacoque died on October 17, 1690, in Paray-le-Monial at the age of 43. She was beatified by Pope Pius IX in 1864 and canonized by Pope Benedict XV in 1920. Her feast day is celebrated on October 16, the day before her death, and the Basilica of the Visitation in Paray-le-Monial stands today as a major pilgrimage site dedicated to her memory. Her legacy extends far beyond the borders of France: devotion to the Sacred Heart of Jesus, as she promoted it, has become one of the most widespread Catholic devotions worldwide, expressed in the Enthronement of the Sacred Heart in homes, the Nine First Fridays devotion, and the Holy Hour of Eucharistic adoration. St. Margaret Mary is the patron saint of devotees of the Sacred Heart and of those suffering from polio, a patronage connected to her long history of illness and to miraculous healings associated with her intercession.

The spiritual theology that emerged from her visions, sometimes called the Alacoque-Colombière spirituality, has shaped Catholic devotional life for over three centuries. Missionaries carried devotion to the Sacred Heart to every continent, and religious congregations specifically dedicated to spreading the devotion were founded in the centuries after her death. The apparitions also contributed to a wider Christocentric emphasis in Catholic piety, focusing on the humanity and love of Christ rather than abstract theological concepts. Margaret Mary's personal correspondence, memoirs, and spiritual notes remain important primary sources for historians of French Catholic spirituality in the 17th century. The 'great revelations' of Paray-le-Monial, as they came to be known, were officially approved for the celebration of the feast in 1856 by Pope Pius IX, and the entire Catholic Church was mandated to observe the feast in 1856, though these precise details of the promulgation history are sometimes given in slightly varying accounts.
