At the end of the 17th century Our Lord appeared to St. Margaret Mary Alacoque and asked her to spread devotion to His Most Sacred Heart by promoting the First Friday devotions. Our Lord made these promises to St. Mary Alacoque regarding those who practice the Nine First Fridays. These are only 6 of the 12 promises.
To meet the requirements for the First Friday Devotion a person must, on each First Friday for nine consecutive months: Attend Holy Mass, Receive Communion, Go to Confession within a period of 8 days before or after the First Friday. The communicant should have the intention, at least implicitly, of making reparation to the Sacred Heart of Jesus for all the sinfulness and ingratitude of men.
