Our Lady’s request and promise to Sr. Lucia on July 13th, 1917:
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 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 meditating on the mysteries of the Rosary, with the purpose of making reparation to my Immaculate Heart.
1. Confess and receive Holy Communion on the First Saturday of five consecutive months. On February 15th, 1926 Sr. Lucia, in answer to a prayer, received from our Blessed Lord an assurance that one could confess within the window of eight days prior or eight days after the First Saturday (the same as one of the usual conditions for gaining a plenary indulgence), providing that one receive Holy Communion in a state of grace.
2. Recite at least five decades of the Rosary at any time or place on the First Saturday, though it is most appropriate to do so publically, before the Blessed Sacrament, before or after Mass.
3. Mediate for an additional fifteen minutes on one or more of the various mysteries of the Rosary, in compliance with Our Lady’s requests to “keep me company fifteen minutes while meditating on the mysteries of the Rosary.” In 1940 it was clarified by Bishop Jose Correia da Silva, the first bishop of Fatima, that the initial recitation of the Rosary does not count for this fifteen minute mediation. This was also confirmed by Sr. Lucia, herself. While it is ideal to mediate on one mystery every month for this additional fifteen minutes of mediation, one is given great latitude, and may mediate even on all the mysteries, according to one’s own attraction or devotional preference.
These meditations can be accomplished by meditative reading on one or more of the mysteries of the Rosary, which would include lectio divina, or by praying an additional Rosary or otherwise using Rosary beads, or whatever means that are suitable for each individual. This additional fifteen minute mediation may take place at any time or place on the First Saturday, but once again it would preferable in front of the Blessed Sacrament, before or after the Mass.
4. And lastly these exercises must be done in reparation, and as was clarified to Sr. Lucia on May 29th, 1930, in reparation for the five principle blasphemies against the Immaculate Heart of Mary (thus five consecutive First Saturdays): (1) blasphemies against her Immaculate Conception; (2) blasphemies against her perpetual virginity; (3) blasphemies against the divine and spiritual Maternity of Mary; (4) blasphemies involved in the disrespect or rejection of her images; and finally (5) the blasphemy of neglecting to implant in the hearts of children a knowledge and love of her Immaculate Heart.
