The Sisters of Mary Reparatrix (French: Sœurs de Marie Reparatrice) are a religious institute of women in the Catholic Church which was founded in France in 1857. Their way of life has been to combine adoration of God with the evangelization of society, especially for women.
The foundress of the congregation was Mother Mary of Jesus, born Émilie d'Oultremont de Warfusée, a member of a prominent Catholic family in Belgium. While she was still a child, her father was appointed as the Belgian Ambassador to the Holy See in Rome.
As a teenager, d'Oultremont was drawn to the consecrated life of a Religious Sister, but, due to the encouragement of her family, she wed at the age of 19. Though it was an arranged marriage, she and her husband fell deeply in love. She lived a happy life with her husband, while both being a member of Roman society and serving the poor of the city. She and her husband had four children before his untimely death in 1847.
The young widow d’Hooghvorst, who had already experienced a mystical vision of God while attending a ball, was drawn more deeply in her spiritual life. With the loss of both her parents by 1851, she decided to withdraw from the demands of her wider family and, in 1854, moved to France with her children. Before her departure, she accepted the invitation of an aunt to visit her at her residence in the Castle of Bauffe, near Chièvres. It was in the chapel of the castle that Emilie had another vision which was to change her life. It occurred on 8 December 1854, the same day as Pope Pius IX declared the doctrine of the Immaculate Conception to be a formal dogma of the Catholic Church.
