Act of Reparation to the Sacred Heart

Devotions

A prayer of sorrow for ingratitude toward Christ’s love, rooted in St. Margaret Mary Alacoque’s reported visions and prescribed by Pope Pius XI for annual public recitation on the Feast of the Sacred Heart.

The Act of Reparation to the Sacred Heart is a prayer in which Catholics express sorrow for indifference and offense against the love of Christ symbolized by his Heart, and renew their own fidelity to him. Its themes trace to St. Margaret Mary Alacoque’s seventeenth-century visions, and Pope Pius XI, in the 1928 encyclical Miserentissimus Redemptor, prescribed that this act be recited publicly in churches throughout the world every year on the Feast of the Sacred Heart, attaching an indulgence to the practice.

What Is This Devotion?

The Act of Reparation to the Sacred Heart is a prayer of sorrow — not for a personal sin alone, but on behalf of the coldness and ingratitude Catholic tradition holds that Christ’s love receives from humanity. Reparation, in this sense, is not paying a debt as if love could be settled like an account; it is uniting oneself, in prayer and intention, to Christ’s own self-offering, so that sorrow for sin becomes part of his redemptive work rather than a separate transaction.

Origin and History

The theme of reparation runs through St. Margaret Mary Alacoque’s reported visions at Paray-le-Monial in the 1670s, in which she described Christ speaking of the ingratitude he receives even from those close to him, and asking for acts of consolation and reparation in response. Devotional reparation texts circulated for generations afterward, but the practice reached its definitive modern form on 8 May 1928, when Pope Pius XI issued the encyclical Miserentissimus Redemptor.

In that encyclical, Pius XI directed that an Act of Reparation — the text he had approved for the purpose — be recited publicly in every church of the Catholic world each year on the Feast of the Sacred Heart, and he raised that feast itself to the rank of a Solemnity.

Catholic Theology

Reparation reflects the Catholic doctrine of the Communion of Saints: because believers are joined to one another and to Christ, the prayer and penance of one member of the Church can be offered on behalf of others, and even on behalf of the Church’s own collective failures in love. Making reparation to the Sacred Heart is an act of solidarity with Christ’s own suffering love, not an attempt to add something his redemption lacks. The Church has always insisted this remain rooted in gratitude and conversion rather than becoming scrupulous or transactional.

How to Practice It

  • Pray the Act of Reparation itself, ideally with attention to its meaning rather than by rote.
  • Where possible, join in its public recitation on the Feast of the Sacred Heart, which is when the Church specifically prescribes it.
  • Pair the prayer with sacramental confession and Holy Communion, since reparation is meant to flow from an examined conscience rather than replace one.
  • Consider praying it as part of First Friday observance, given the shared roots of both practices in Margaret Mary’s reported visions.

Associated Prayers

When It’s Observed

The Church specifically prescribes public recitation of this Act on the Feast of the Sacred Heart, a moveable Solemnity kept on the Friday nineteen days after Pentecost. Many parishes and individuals also pray it on First Fridays or during June, traditionally kept as the Month of the Sacred Heart.

Church Status

This is one of the more formally established devotional texts in the Church’s life: Pope Pius XI did not merely permit it but directed its public recitation in every Catholic church annually, a stronger institutional footing than most popular devotions receive. It remains, even so, a devotional rather than strictly liturgical text — it supplements the Mass of the feast rather than forming part of the Mass itself.

Private Revelation

The Act’s underlying themes trace back to St. Margaret Mary Alacoque’s reported visions, though the specific prayer text later approved for public use is a later composition rather than a word-for-word transcription of anything she is recorded as having received. As with any private revelation, the visions themselves are not binding on Catholic belief (CCC §67); what carries the Church’s authority here is Pope Pius XI’s own 1928 act of prescribing the prayer, not a claim about the historical detail behind it.

Promises and Indulgences

Under the Church’s Manual of Indulgences, a plenary indulgence is granted, under the Church’s usual conditions — sacramental confession, Holy Communion, prayer for the pope’s intentions, and full detachment from sin — to the faithful who publicly recite this Act of Reparation on the Feast of the Sacred Heart; a partial indulgence is available when it is prayed at other times. Because the precise conditions attached to any indulgence can be revised, readers should confirm current wording against the Church’s Manual of Indulgences rather than an older prayer card.

Common Misconceptions

“Reparation means paying God back for sin, as if love were a debt.”

Catholic theology does not treat reparation as a financial transaction. It is an act of loving solidarity with Christ’s own self-offering, not a payment that changes God’s disposition toward humanity, which is already merciful.

“This prayer can only be prayed on the Feast of the Sacred Heart.”

The Church specifically prescribes public recitation on that feast, but nothing prevents praying the Act privately at any time; only the plenary indulgence is tied to the feast-day recitation.

Frequently Asked Questions

Who wrote the Act of Reparation used today?

The text approved for public use follows Pope Pius XI’s 1928 encyclical Miserentissimus Redemptor, though reparation prayers to the Sacred Heart circulated in various forms before that date.

Is the Act of Reparation the same prayer as the Act of Consecration to the Sacred Heart?

No. Consecration entrusts a person or family to Christ’s love; reparation expresses sorrow for offenses against that love. They are often prayed together but are distinct texts. See our separate page on consecration.

Do I need a priest to pray this?

No. While the Church calls for its public, communal recitation on the feast day, an individual can pray the Act privately at any time.
