The rosary is one of the most powerful sacramentals of the Catholic Church originating in the early centuries of Christianity, once called "Mary's Psalter". The rosary as we know it today was given by the Blessed Virgin Mary to St. Dominic de Guzman, founder of the Dominican Order, in the 12th century as an efficacious prayer and spiritual weapon for the salvation of souls. Whenever the prayers are said on the rosary beads, the intercession of the Blessed Mother is invoked for the intentions we hold in our hearts.
