In the year 1917 Our Lady appeared before three shepherd children, they Lucia, Jacinta, and their brother Francisco.
The children were very shocked and a little scared when they heard a clap of thunder and saw an Angel appear to them. The 3 children fell to the ground in adoration, the Angel told them that the Blessed Virgin Mary would visit them soon and they must be good!
The Blessed Virgin Mary did appear to the 3 children and gave them 3 important messages, but the most important message that Our Lady gave to the children was to love God, to be good and to offer penance for the souls of great sinners.
The Blessed Mother told the children that if people did not live good lives this would make God angry and the way to soften God's anger was to do acts of penance for the sins of the world.
Lucia saw a cloud in the shape of a human being, moving across the sky and hovering over a pine tree. Another time at the same place, the children were caught in a hail storm and hid in a cave, ate lunch, and quickly prayed the Rosary. They walked outside, strong winds picked up, Lucia looked up and saw a cloud just like the one she saw before. The cloud was an angel of peace and asked the children to pray with him.
The Fatima prayer:
My God I believe, I adore, and I love You. I beg pardon for those who do not believe, do not adore, do not hope, and do not love thee." Repeating the prayer 3 times. He made additional appearance his last in October of 1916 this time he brought a chalice, and suspended it with a host. and asked the children to drink.
During the time, World War I was in full force and the Pope asked all to pray. * days after the Pope asked people to pray, the children saw a great light in the sky. In the center of the light stood a Lady dressed in pure white. Her hands folded and in her right hand a Rosary. Our Lady asked the children to come to the same spot for 6 months on the 13th day at the same hour. On the seventh time she would tell them who she was. He told them she was the "Queen of the Holy Rosary".
