The Fatima Prayer: What It Is, Where It Came From, and How to Pray It

If you have ever prayed the Holy Rosary, you have prayed the Fatima Prayer — even if you did not know it by name. This brief but profound prayer, also known as the "O My Jesus" prayer, is recited after each decade of the Rosary. Its origins lie in one of the most significant supernatural events of the 20th century: the apparitions of Our Lady of Fatima in 1917. Understanding where this prayer comes from and what it asks helps us pray it with far greater depth.

The Apparitions at Fatima

In 1917, the Virgin Mary appeared six times — from May through October — to three shepherd children near the small village of Fátima in Portugal: Lúcia dos Santos (age 10), and her cousins Francisco and Jacinta Marto (ages 9 and 7). These apparitions were accompanied by extraordinary signs, culminating in the Miracle of the Sun on October 13, 1917, witnessed by approximately 70,000 people.

Our Lady entrusted the children with three secrets and a series of requests: prayer, penance, and the consecration of Russia to her Immaculate Heart. Among the most specific requests was that the Fatima Prayer be added to the Rosary after each decade — a change that spread throughout the Catholic world in the decades following the apparitions.

The Angel of Peace

Before Mary appeared, the three children received three visits from an angel in 1916 — now venerated as the Angel of Peace (or the Angel of Portugal). The angel taught them prayers of adoration and reparation, prostrating himself before a Host and Chalice suspended in the air. One prayer he taught them contains the same spirit of reparation and mercy that would characterize the entire Fatima message:

O Most Holy Trinity, Father, Son and Holy Spirit, I adore Thee profoundly. I offer Thee the most precious Body, Blood, Soul and Divinity of Jesus Christ, present in all the tabernacles of the world, in reparation for the outrages, sacrileges and indifference with which He Himself is offended. And through the infinite merits of His most Sacred Heart and the Immaculate Heart of Mary, I beg of Thee the conversion of poor sinners.

This preparatory angelic visitation set the tone for the divine message that would follow.

The Fatima Prayer: Text and Meaning

The Fatima Prayer itself is short — only a few lines — but it is dense with theological meaning. Our Lady asked that it be prayed after the Glory Be at the end of each decade of the Rosary. Here is the full text:

O my Jesus, forgive us our sins, save us from the fires of hell, lead all souls to Heaven, especially those in most need of Thy mercy. Amen.

This prayer asks for three things: forgiveness for our sins, protection from eternal damnation, and the salvation of all souls — with a particular urgency for those most in danger. That final phrase, "especially those in most need of Thy mercy," has struck generations of Catholics with its charity. Rather than praying only for the virtuous or for those we love, the Fatima Prayer asks mercy for the worst sinners — those who are, spiritually, in the greatest peril.

This universality of intention is consistent with the whole Fatima message, in which Our Lady expressed deep sorrow over souls falling into hell "like snowflakes" for want of prayer and penance on their behalf.

Its Place in the Rosary

The Fatima Prayer is inserted into the Rosary immediately after the Glory Be and before announcing the next mystery. The standard sequence for each decade is:

Our Father → 10 Hail Marys → Glory Be → Fatima Prayer → [Announce next mystery]

While technically an addition to the original structure of the Rosary, the prayer has been so thoroughly adopted that most Catholic families, parishes, and prayer groups include it as a matter of course. It has been recommended by multiple popes and embraced as an organic development of the Rosary devotion.

Variations in Different Traditions

While the prayer above is the most commonly used English translation, slight variations exist. Some traditions omit "Amen" until the very end of a set of mysteries; others use slightly different wording such as "lead all souls to Heaven, especially those who have most need of Thy mercy." These are not significant theological differences — all versions express the same petition. The most important thing is the sincerity and attention with which the prayer is offered.

In some Eastern-rite Catholic communities and in certain traditional Latin Mass circles, the Fatima Prayer is not included, as it postdates the classical form of the Rosary. This does not diminish its value — it simply reflects the organic diversity of Catholic prayer tradition.

Pray It with the Rosary Today

The Fatima Prayer is most powerful when prayed in its proper context — as part of the full Holy Rosary, offered as a sacrifice of intercession for souls. The Traditio Prayer Chapel guides you through every decade of the Rosary, including the Fatima Prayer after each Glory Be.
