The most significant source for the devotion to the Sacred Heart in the form it is known today was Saint Margaret Mary Alacoque (1647–1690), a nun of the Order of the Visitation of Holy Mary, who claimed to have received apparitions of Jesus Christ in the Burgundian French village of Paray-le-Monial, the first on 27 December 1673, the feast of Saint John the Evangelist, and the final one 18 months later, revealing the form of the devotion, the chief features being reception of Holy Communion on the first Friday of each month, Eucharistic adoration during a "Holy hour" on Thursdays, and the celebration of the Feast of the Sacred Heart. She said that in her vision she was instructed to spend an hour every Thursday night to meditate on Jesus' Agony in the Garden of Gethsemane.
