Establishing the rosary

A standard fifteen Mysteries of the Rosary, based on the long-standing custom, was established by Pope Pius V in the 16th century, grouping the mysteries in three sets: the Joyful Mysteries, the Sorrowful Mysteries, and the Glorious Mysteries. In 2002 Pope John Paul II suggested a new optional set of five, called the Luminous Mysteries, bringing the total number of mysteries to twenty.
