Do we truly understand the immense power of the Rosary—so simple, so humble, so accessible, and so widely spread through popular devotion? “The Holy Angels in Heaven salute the Most Blessed Virgin with the Hail Mary not audibly but with their angelic mind. For they are fully aware that through the Hail Mary reparation was made for the fallen angels’ sin, God became man, and the world was renewed,” says Blessed Alan de la Roche.

The miracles performed through the Rosary are countless. At the most critical moments in history, the Rosary has played a decisive role in overcoming calamities that had reached their peak, often in a prodigious manner. In the time of Saint Dominic, the Faith was threatened by the Albigensian heresy, and the Saint employed the Rosary to safeguard orthodoxy. At the Battle of Lepanto, the visible structure of the Church and Christian civilization stood on the brink of collapse. The Rosary of Saint Pius V obtained for Don Juan of Austria the same victory that the arms of Moses, raised on the mountain, won for Joshua against the Amalekites (cf. Ex 17:8–13).

Fr. Antonio Royo Marín, one of the most renowned Dominican theologians of the past century, affirms that “without any doubt the Rosary is the most excellent of Marian devotions.” Following his clear and progressive reasoning, he adds that this is confirmed by the Virgin herself, by the official Magisterium of the Church, and by the very structure and theological richness of the Rosary.
