Fifteen years ago, on Oct. 16, 2002, Pope St. John Paul II released his apostolic letter Rosarium Virginis Mariae (“The Rosary of the Virgin Mary”), which introduced to the Church a new set of mysteries for the Rosary to complement the traditional 15. In addition to the Joyful, Sorrowful and Glorious Mysteries, John Paul II recommended to the faithful the Luminous Mysteries, which he said brought out fully “the Christological depth of the Rosary” by including “the mysteries of Christ’s public ministry between his baptism and his passion” (No. 19). The pope said in the letter that he had no intention to curtail “the freedom of individuals and communities” to pray the Rosary as they preferred. His aim was to help the Church rediscover the beauty and power of the Rosary, which he hoped would lead to a greater practice of prayer, a closer walk with Christ and, thereby, a more lasting peace in the world, beginning within the family and spreading to society at large (see Nos. 40-41).
