Pardon Prayer taught to the children by the Angel in the spring of 1916
My God, I believe, I adore, I hope, and I love thee! I beg pardon for those who do not believe, do not adore, do not hope, and do not love thee.
The Angel’s Prayer, taught to the children in the autumn of 1916
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 by which He is offended. By the infinite merits of the Sacred Heart of Jesus and the Immaculate Heart of Mary, I beg the conversion of poor sinners.
Eucharistic Prayer – repeated by children in their hearts during 13 May 1917 apparition
Most Holy Trinity, I adore You! My God, my God, I love You in the Most Blessed Sacrament.
Sacrifice Prayer – taught to the children by Our Lady
O my Jesus, it is for love of You, in reparation for the offenses committed against the Immaculate Heart of Mary, and for the conversion of poor sinners.
Decade Prayer – Our Lady asked that this prayer be said at the end of each decade of the Rosary
O my Jesus, forgive us our sins; save us from the fires of hell; lead all souls into Heaven, especially those who are in most need of thy mercy.
