The Rosary is a Scripture-based prayer. It begins with the Apostles’ Creed, which summarizes the great mysteries of the Catholic faith. The Our Father, which introduces each mystery, is from the Gospels. The first part of the Hail Mary is the angel’s words announcing Christ’s birth and Elizabeth’s greeting to Mary. St. Pius V officially added the second part of the Hail Mary. The Mysteries of the Rosary center on the events of Christ’s life.

According to pious tradition, the concept of the Rosary was given to Saint Dominic of Osma, founder of the Dominican Order, in an apparition of the Blessed Virgin Mary during the year 1214. This Marian apparition received the title of “Our Lady of the Rosary.”
