It's no secret that the Pope feels a strong devotion towards Our Lady. The day after he was elected, he went to the Basilica of St. Mary Major to pray before an image of the Virgin Mary. Then most recently, when he met with Catholic lay movements, he explained exactly why he likes to pray the rosary on a daily basis.
"The Virgin Mary is our mother. She knows everything. So, it's important for us to pray to Our Lady, so that she, as a mother, can give us strength. It has to do with our weakness, at least in my experience. One thing that gives me strength, is praying the Rosary to the Virgin Mary every day. I feel it. I pray to her and I feel strong.”
Precisely during the Rosary prayer on Friday, an image of Our Lady will be carried out in St. Peter's Square. The invitation is open for all to take part.
