The pious practice of honoring the Blessed Mother on Saturday is an ancient custom largely attributed to the Benedictine monkAlcuin, "Minister of Education" at the court of Charlemagne, composed a Votive mass formulary for each day of the week. Alcuin assigned two formularies to Saturday in honor of Our Lady. The practice was quickly embraced by both clergy and laity. The practice of Reparation to the Immaculate Heart of Mary on the First Saturday was initiated in Rovigo, Italy by Mary Inglese, a Servitetertiary in 1889. She started among her friends the pious practice of "Communion in Reparation to the Immaculate Heart of Mary". The practice was endorsed by Bishop Antonio Polin of the Diocese of Adria and was taken up by sodalities throughout Italy and elsewhere. On July 1, 1905, Pope Pius X approved and granted indulgences for the practice of the First Saturdays of twelve consecutive months in honor of the Immaculate Conception. This practice greatly resembled the reported request of the Virgin Mary at the Pontevedra apparitions. Inglese wished to establish a religious congregation dedicated to the apostolate of Marian Reparation. Bishop Tommaso Pio Boggiani recommended that she join the Servite sisters, known for their devotion to Our Lady of Sorrows. She joined the Servites as Sister Mary Dolores in 1911. She and foundress Mother Mary Elisa Andreoli revised the rule making propagation of Communion of Reparation on the First Saturday of each month the congregation's main apostolate. They also changed the name of the group from "Servants of Mary" to "Servants of Mary of Reparation". The sisters published a monthly magazine that helped spread the devotion throughout Europe.
Pontevedra
At the age of 14, Lúcia Santos, one of the purported Portuguese seers of Our Lady of Fátima was admitted as a boarder to the school of the Sisters of St. Dorothy in Vilar, near the city of Porto. On October 24, 1925, she entered the Institute of the Sisters of St. Dorothy as a postulant in the convent in Tui, Spain, just across the northern Portuguese border. Sister Lucia later reported that on December 10, 1925, the Virgin Mary appeared to her at the convent in Pontevedra, Spain, and by Her side, elevated on a luminous cloud, was the Child Jesus. According to Lucia, Mary requested the institution of the Devotion of the Five First Saturdays in reparation to her Immaculate Heart. Such sorrow is particularly bitterly endured on Holy Saturday after Jesus was placed on the Sepulcher. Devotees of Fátima believe that the First Saturdays help to console the sorrows of God, Jesus, and the Virgin Mary for the sins against Her Immaculate Heart.
The Act of Reparation
When Sister Lúcia experienced the Pontevedra apparitions of the Blessed Virgin Mary, she heard her promise to grant great graces, especially at the hour of death, in particular the salvation of the soul, for the believer who for Five Consecutive First Saturdays of Month receives Holy Communion and practices the following exercises as an Act of Reparation to the Immaculate Heart of the Blessed Virgin Mary, Mother of God and Queen of Heaven:
The confession can take place within eight days before or even after the Holy Communion is received, but the Holy Communion shall be received with dignity, in a state of Grace, keeping in mind that Jesus is physically present in the Eucharist. The Intention of making reparation to the Immaculate Heart of Mary may be kept to oneself; it is not necessary to notify the confessorpriest.
To receive Holy Communion
The Holy Communion has to be received within the 24 hours of the first Saturday of the Month. Attendance to Holy Mass is optional. Receiving Holy Communion as part of this devotion must be consciously intended as an Act of Reparation to the Immaculate Heart. The devotee need not tell anyone else, but keep it in mind. To avoid omitting the Intention every Saturday, the General Intention for the devotion of the Act of Reparation can be mentally or outspokenly stated before starting the First Saturdays. If a person has a valid reason not to attend Mass, the devotee may consult a priest about receiving Communion privately or on another day with the intention of making this Communion as part of the devotion.
