Who Was St. Margaret Mary Alacoque?
Margaret Mary Alacoque was born on July 22, 1647, at L'Hautecour in Burgundy. She entered the Visitation convent at Paray-le-Monial in 1671 after childhood illness and family loss. From 1673 to 1675 she reported apparitions of the Sacred Heart asking for a feast, Communion on First Fridays, and a Holy Hour on Thursdays.
Opposition within the convent eased after St. Claude La Colombière validated her experiences. She died on October 17, 1690; her feast is October 16. Pope Pius XII extended the feast of the Sacred Heart worldwide.
After the death of her father, Margaret and her family were forced into poverty when a relative refused to hand over the family's assets. Margaret's only comfort in life was her frequent visits to pray before the Blessed Sacrament at a local church. At 17-years-old, Margaret's family was able to regain control of their assets. Margaret's mother started encouraging her to become more social, in hopes she would find a suitable husband.
One night, after attending a ball in an evening dress, Margaret had a vision of Christ, scourged and bloody. He accused Margaret of forgetting about him. He showed her that His heart was full of love for her because of the promise she made to His Blessed Mother as a child. After this vision, Margaret was determined to fulfill the vow she made years ago. She entered the Visitation Convent at Paray-le-Monial in May 1671 to become a nun.

The Sacred Heart at Paray-le-Monial
St. Margaret Mary Alacoque is remembered as Visitation nun who spread devotion to the Sacred Heart at Paray-le-Monial. Christ's human Heart is the sign of God's merciful love wounded by sin.
Margaret Mary received visions of Christ's Heart burning with love for an indifferent world. Her confessor St. Claude La Colombière defended revelations skeptics mocked. She promoted First Fridays and Holy Hour reparation that spread across the Catholic world.
Reparation is not groveling but returning love for love. This is not a private hobby of specialists. It is why the calendar still names October 16.
On this feast the Church is not only telling a story; she is keeping a school. These visions showed her the "form of the devotion, the chief features being reception of Holy Communion on the first Friday of each month, Eucharistic adoration during a 'Holy hour' on Thursdays, and the celebration of the Feast of the Sacred Heart." The Lord Jesus requested His love be made evident through her. In her vision, she was instructed to spend an hour every Thursday night meditating on Jesus' Agony in the Garden of Gethsemane, a practice, known as "The Holy Hour," that later became widespread.
Reparation Is Love Returned, Not Groveling

In December 1673, Jesus appeared to Margaret Mary again, and allowed her to rest her head on His heart. His human heart was to be the symbol of His divine-human love. He revealed to her the wonders of His love. He explained to her that he wished to make these wonders known to all the world, and that He chose her for His work. Margaret Mary convinced her superior, Mother de Saumaise, her visions were authentic. However, she struggled with convincing others of the validity of her apparitions, even those in her own community.
A group of theologians declared her visions delusions and suggested she eat better. Even parents of children she instructed began calling her an imposter. Margaret eventually gained the support from the community's confessor, St. Claude de la Colombiere, who declared her visions were genuine. Finally, all opposition from the community, regarding Margaret's visions, ended in 1683, when Margaret Mary became the assistant to the Superior.
