History: During the period of November 24 1946 to December 8, 1947, the Blessed Mother appeared to Sister Pierina in a little church in Montichiari, Italy, eleven times.
On the first appearance the Blessed Mother told Sister Pierina She wanted to be known as the Mystical Rose and that an hour of grace should be kept at noon, December 8th, in all the Catholic Churches of the world. The Blessed Mother wanted this to be known through all Italy, and the entire world.
It was November 16, 1947 when Sister Pierina was finishing Her Thanksgiving after Holy Communion when she saw a great light. She then saw a vision of the Blessed Mother as the Mystical Rose.
Sister was so deeply moved by the stunning beauty of Our Lady that she began talking to Her. All of a sudden a gentle force made her kneel down in front of Our Lady. The Blessed Mother spoke these words. "My Son is so greatly offended by the sins of impurity. He is already planning to send the deluge upon the people, for their destruction, but I have asked Him to show mercy, and not send the destruction. So that is why I have appeared, to ask for penance and atonement for the sins of impurity."
On the 22nd of November, Sister Pierina felt the overwhelming urge to go to church at 4:00. The Mother Superior, four Sisters, and a group of friends accompanied her. They were all saying the Rosary when the Blessed Mother appeared as before.
Again, Our Lady asked for penance. She said, "Penance is nothing more than accepting all our crosses daily willingly. No matter how small, accept them with love." At this time She told Sister Pierina to come again on December 8th at noon. "This will be my Hour of Grace." The Sister asked how she was to prepare for this Hour of Grace? To which the Blessed Mother said, "with prayers and penance. Pray the 51st psalm with outstretched arms three times. During the Hour of Grace, many spiritual graces would be granted. The most hard-hearted sinners will be touched by the grace of God." The Blessed Mother promised that whatever a person asked her for during this Hour of Grace (even in impossible cases) would be granted to them, if it was in accordance with the Will of the Eternal Father.
On the morning of December 8th, people began arriving at the little church at 8:00 in the morning form neighbouring towns. By noon, some 10,000 people had gathered to see the Blessed Mother… In the most gentle and loving voice, Our Lady smiled ad began to speak [to Sister Pierina]: "I am the Immaculate Conception, the Mother of my Beloved Son, Jesus. I want to be known as the Mystical Rose. My wish is that every year on the 8th of December, at noon, an Hour of Grace will be installed. Many spiritual graces and physical blessings will be received by those who pray, undisturbed, during this hour."
