Have you ever heard the terms “First Friday” and “First Saturday” thrown around in Catholic circles? The First Friday devotion and the First Saturday devotion arose from separate private revelations. The First Friday devotion is associated with the Sacred Heart of Jesus, while the First Saturday devotion is associated with the Immaculate Heart of Mary.
Both devotions involve receiving Holy Communion on a certain number of consecutive first Fridays or first Saturdays of the month. You can think of it almost like a novena which is prayed on consecutive days for a particular intention, but instead, these devotions are performed on consecutive months. The devotions are similar in that they call on the faithful to “stand in the gap” by doing penance for sinners, and both give a special promise of Divine assistance at the hour of death, that is, the promise of dying in a state of grace and therefore obtaining heaven.
First Friday Devotion: Typically, nine consecutive Fridays in reparation to the Sacred Heart of Jesus.
First Saturday Devotion: Typically, five consecutive Saturdays in reparation to the Immaculate Heart of Mary.
