Biography
Louis-Marie Grignion de Montfort was a man of radical devotion, a wandering preacher whose life was a whirlwind of poverty, controversy, and mystical fervor in 18th-century France. Rejecting comfortable clerical posts, he chose to walk the countryside, preaching dramatic, emotional missions to the rural poor that often put him at odds with local authorities and even fellow clergy. His lasting legacy is written: in works like 'True Devotion to Mary,' he crafted a rigorous, totalizing path of spiritual surrender to Jesus through Mary, a concept he called 'Holy Slavery.' These writings, nearly forgotten after his death, were rediscovered and became central to a modern revival in Marian piety. His influence extended directly to the Vatican, shaping the personal spirituality of Pope John Paul II, who took his papal motto from Montfort's writings. The religious orders he founded, the Montfortians and the Daughters of Wisdom, continue his work of evangelization and care for the sick.
