The visions of St. Margaret Mary Alacoque
Between 1673 and 1675, at the Visitation convent of Paray-le-Monial in France, Sister Margaret Mary Alacoque received a series of apparitions of Jesus Christ. In the most significant of these, Jesus revealed His heart to her, surrounded by thorns and surmounted by a cross, radiant with flames of love, and told her that this Heart had loved humanity so much that it had spared nothing — yet received in return only coldness and ingratitude.
He asked that a feast be established in honor of His Heart, that the faithful receive Communion on the First Friday of each month, and that an hour of adoration be kept every Thursday night in memory of His agony in the Garden of Gethsemane.
The Twelve Promises
Through St. Margaret Mary, Jesus revealed twelve promises to those devoted to His Sacred Heart. Among them: He would give peace in their families, comfort them in their afflictions, bless every place where an image of His Heart was honored, and grant sinners a fount of infinite mercy. The most famous of the twelve is the promise of final perseverance — that those who receive Communion on nine consecutive First Fridays would not die without receiving the sacraments, securing His grace at the hour of death.
"Behold this Heart which has so loved men that it has spared nothing, even to exhausting and consuming itself, in order to testify to them its love."
The devotion spreads through the Church
Initially met with skepticism, the Sacred Heart devotion spread through the efforts of Margaret Mary's Jesuit confessor, St. Claude La Colombière, and gradually gained approval from Rome. Pope Pius IX extended the feast to the universal Church in 1856. Devotion to the Sacred Heart became one of the most visible expressions of Catholic piety in the centuries that followed, with images of the Sacred Heart enshrined in homes, churches, and schools throughout the world.
Many Catholic families historically consecrated their households to the Sacred Heart, placing an image of Christ's Heart in a place of honor as a sign that Christ reigned over their home and family life.
The First Fridays devotion
The practice of the First Fridays — attending Mass and receiving Communion on the first Friday of nine consecutive months — remains one of the most widely practiced Catholic devotions tied to a specific promise. It is often undertaken as an act of reparation for sin and indifference, and in trust in Christ's promise of final grace.
Why Catholics turn to the Sacred Heart
The Sacred Heart devotion speaks to something deeply human: the desire to be loved unconditionally, and the need to respond to love with love. Catholics turn to it when:
- Seeking consolation in suffering or loss
- Consecrating their family or home to Christ
- Making an act of reparation for sin or indifference
- Praying for final perseverance and a peaceful death
- Wanting a tangible symbol of God's personal, burning love
