The practice of the First Saturday devotion was requested by Our Lady of Fatima, who appeared to three shepherd children in Fatima, Portugal, multiple times starting in 1917.
She said to Lucia, the oldest of the three children:
“I shall come to ask . . . that on the First Saturday of every month, Communions of reparation be made in atonement for the sins of the world.”
Years later she repeated her request to Sr. Lucia, the only one still living of the three young Fatima seers, while she was a postulant sister living in a convent in Spain:
“Look, my daughter, at my Heart, surrounded with thorns with which ungrateful men pierce me at very moment by their blasphemies and ingratitude. You at least try to console me, and say 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, shall confess, receive Holy Communion, recite five decades of the rosary, and keep me company for 15 minutes while meditating on the 15 mysteries of the rosary, with the intention of making reparation to me.”
There are five requirements to obtain this promise from the Immaculate Heart of Mary. On five consecutive first Saturdays of the month, one should:
1. Have the intention of consoling the Immaculate Heart in a spirit of reparation.
2. Go to confession (within eight days before or after the first Saturday).
3. Receive Holy Communion.
4. Say five decades of the Holy Rosary.
5. Meditate for 15 minutes on the mysteries of the Holy Rosary with the goal of keeping Our Lady company (for example, while in church or before an image or statue of Our Lady).
Our Lord appeared to Sr. Lucia on May 29, 1930 and gave her the reason behind the five Saturdays devotion. It is because there are five types of offenses and blasphemies committed against the Immaculate Heart of Mary:
1. Blasphemies against the Immaculate Conception
2. Blasphemies against Our Lady’s perpetual virginity
3. Blasphemies against her divine maternity, in refusing at the same time to recognize her as the Mother of men
4. Blasphemies of those who publicly seek to sow in the hearts of children, indifference or scorn or even hatred of their Immaculate Mother
5. Offenses of those who outrage Our Lady directly in her holy images
Never think that Jesus is indifferent to whether or not His mother is honored!
While keeping up with these devotions over five or nine consecutive months is not easy, the reward for making the effort is eternal. Look again at those promises from Jesus and Mary!
Nothing in this life is more important than holy religion (living according to the will of God as revealed through his Church), offering yourself to God as a self-gift for the benefit of others (Christ-like reparation for the sins of others), and obtaining salvation through Jesus Christ (joining the saints in heaven for all eternity). So, resolve to make the effort to do one or the other (or both!) of these devotions, and pray for the grace to follow through to the end. God always gives the grace to those who wish to faithfully accomplish his requests!
