First Friday Devotion
The First Friday Devotion to the Sacred Heart of Jesus is based on a promise made by our Lord Jesus Christ during an Apparition to St. Margaret Mary Alacoque. This promise was implicitly approved by the Church in the 1920 canonization of St. Margaret Mary.
The 12 Promises are contained in a letter written in May, 1688, by St. Margaret Mary to Mother Saumaise: See More

First Saturday Devotion
During her July 1917 apparition at Fatima, Our Lady said to Lucia, "Behold, my daughter, my Heart encircled with thorns, with which ungrateful men pierce It at every moment by their blasphemies and ingratitude. Give me consolation, you, at least; and make known on my behalf that I promise to assist at the hour of death, with the graces necessary for salvation, all those who on the First Saturday of five consecutive months confess their sins, receive Holy Communion, recite five decades of the Rosary, and keep me company for fifteen minutes while meditating on the mysteries of the Rosary, with the purpose of making reparation to my Immaculate Heart."  See More
