The Rosary, though clearly Marian in character, is at heart a Christocentric prayer. In the sobriety of its elements, it has all the depth of the Gospel message in its entirety, of which it can be said to be a compendium. It is an echo of the prayer of Mary, her perennial Magnificat for the work of the redemptive Incarnation which began in her virginal womb. With the Rosary, the Christian people sits at the school of Mary and is led to contemplate the beauty on the face of Christ and to experience the depths of his love. Through the Rosary the faithful receive abundant grace, as though from the very hands of the Mother of the Redeemer.
—From On the Most Holy Rosary (Rosarium Virginis Mariae)
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. There are four sets of Mysteries: Joyful, Sorrowful, Glorious and––added by Saint John Paul II in 2002––the Luminous. (UCCB Website)
