St. Margaret Mary Alacoque

St. Margaret Mary Alacoque

St. Margaret Mary Alacoque was a French Roman Catholic nun and mystic, who promoted devotion to the Sacred Heart of Jesus in its modern form. She worked to prove the genuineness of her vocation and her visions of Jesus and Mary relating to the Sacred Heart. She was initially rebuffed by her mother superior and was unable to convince theologians of the validity of her visions. A noted exception was Saint Claude de la Colombiere, who supported her. The devotion to the Sacred Heart was officially recognized 75 years after Alacoque's death. In his encyclical Miserentissimus Redemptor, Pope Pius XI stated that Jesus Christ had "manifested Himself" to Saint Margaret and referred to the conversation between Jesus and Saint Margaret several times.
