Nun, Mystic
Sanctified Life
July 22, 1647 — October 17, 1690
L'Hautecour, Burgundy, France
Also Known As
"I need nothing but God, and to lose myself in the Heart of Jesus."
Margaret Mary Alacoque was a French Visitation nun whose private visions in Burgundy reshaped Catholic devotion worldwide. In June 1675, Christ appeared and asked her to spread devotion to His Sacred Heart — a movement already beginning to travel through Jesuit networks before she died at forty-three at Paray-le-Monial.

Life & Times
Early Life
Born in Burgundy in 1647, Margaret Mary lost her father at eight and was bedridden for four years. She entered the Visitation convent at Paray-le-Monial at twenty-four.
Turning Point
In June 1675 Christ appeared and asked her to establish a feast honoring His Sacred Heart. Her superiors were skeptical; only her confessor Père de la Colombière provided the discernment she needed.
Legacy
Died at forty-three on October 17, 1690, her final words: 'I need nothing but God.' The Sacred Heart devotion she transmitted swept the Catholic world; she was canonized in 1920.

Words & Wisdom
“Look upon yourself as a tree planted beside the water, which bears its fruit in due season; the more it is shaken by the wind, the deeper it strikes its roots into the ground.”
The Twelve Promises of the Sacred Heart
A series of promises reported by Margaret Mary as given by Christ to those devoted to His Sacred Heart — including peace in families, consolation in trials, and the grace of final perseverance. Received privately, they became one of the most widely circulated devotional texts in modern Catholicism.
O Saint Margaret Mary Alacoque, apostle of the Sacred Heart and vessel of divine love's most intimate request, you lay paralyzed as a child and rose to become the instrument through whom Christ spoke His longing to a forgetful world. You were doubted by your superiors, dismissed by theologians, and hidden from all recognition — yet you persisted under obedience, writing what you had seen because God asked it of you, not because the world would believe it. You said you needed nothing but God, and to lose yourself in the Heart of Jesus — and you proved it with your life. Patron of all who have lost parents, who know the particular grief of early abandonment — intercede for us. Patron of all who suffer in body, who have lain helpless and found God precisely there — pray for us. Patron of all who love the Sacred Heart, who seek to offer reparation for the world's indifference — accompany us. Teach us the patience of your paralysis, the courage of your visions, and the simplicity of your final surrender. May we learn to be trees planted beside the water — shaken by every wind, yet driving our roots deeper into the ground with every storm. Amen.
