Two friends and I felt sad and worried about the situation in the world: the pandemic and its tragic results, the non-respect for Life, the inversion of moral values, and the attacks against the Church. We had a strong desire to do something, but we didn't know what...
So we gave this desire to the Lord, asking Him to enlighten and guide us. We prayed, and one of us, Catherine, spent several hours in prayer on September 21, 2020, in the Carmel of Chambéry (French Alps) before the Blessed Sacrament. While there, she received an interior vision.
The first image of this vision was the fresco in the Crypt of the Shrine of Our Lady of Myans in Savoy, France. This fresco tells of the miracle that took place in 1248, when the Granier mountain collapsed. The whole region had been swept away by mudslides, except for the monks who were praying before the statue of Our Lady of Myans. The fresco shows some demons trying to destroy the shrine with huge rocks, admitting their defeat and saying: "We can't, because the Virgin Mary won't let us."
Then Catherine saw a second image: it was the Chapel of Perpetual Adoration in Chambéry that appeared.
Inside was a huge rosary (...) laid out on the floor, before the Blessed Sacrament. And a part of this rosary went out through the door into the street where it continued to unfold. Outside, its beads were immediately transformed and became the ramparts of a fortress. This great wall constituted a formidable protection... While this vision was unfolding, she heard two words: "Perpetual rosary".
In the days following this vision, we discerned in prayer, with a priest, the meaning that it could have. Then we responded to the Lord's call, convinced of the power of the rosary, this extraordinary bulwark that will increasingly protect the whole world! This is how the 'Perpetual Rosary for the World' began on October 1, 2020.
