During the first apparition of the Angel of Peace to the 3 Shepherd Children (Lucia, Francisco and Jacinta) at Fatima in the Spring of 1916, the angel knelt, bending his forehead to the ground, and recited this prayer. The children repeated the words. After repeating the prayer 3 times, the angel rose and told the children to pray in this manner and that the hearts of Jesus and Mary are ready to listen to their prayers.
My God, I believe, I adore, I hope, and I love You. I ask forgiveness for those who do not believe, do not adore, do not hope, and do not love You.
