Marguerite Marie Alacoque
1647-1690. Founder of the devotion to the Sacred Heart of Jesus. She entered the Visitation convent at Paray-le-Moniae, central France, in 1671, and after a regime of severe austerities declared that Christ had revealed to her His heart burning with love for man and had commanded her to establish the Holy Hour, Communion on the first Friday of each month, and the feast of the Sacred Heart to be observed on the Friday after the octave of Corpus Christi. The skepticism with which her visions were at first regarded was gradually dispelled, and devotion to the Sacred Heart quickly spread throughout the Christian world. She was pronounced venerable in 1824, beatified in 1864, canonized in 1920.
