J.M.J. From the Apostolic Letter Rosarium Virginis Mariae (October 16, 2002) of Saint John Paul II:
"8. It would be impossible to name all the many Saints who discovered in the Rosary a genuine path to growth in holiness. We need but mention Saint Louis Marie Grignion de Montfort, the author of an excellent work on the Rosary,(12) and, closer to ourselves, Padre Pio of Pietrelcina, whom I recently had the joy of canonizing. As a true apostle of the Rosary, Blessed Bartolo Longo had a special charism. His path to holiness rested on an inspiration heard in the depths of his heart: 'Whoever spreads the Rosary is saved!'.(13) As a result, he felt called to build a Church dedicated to Our Lady of the Holy Rosary in Pompei, against the background of the ruins of the ancient city, which scarcely heard the proclamation of Christ before being buried in 79 A.D. during an eruption of Mount Vesuvius, only to emerge centuries later from its ashes as a witness to the lights and shadows of classical civilization. By his whole life's work and especially by the practice of the 'Fifteen Saturdays', Bartolo Longo promoted the Christocentric and contemplative heart of the Rosary, and received great encouragement and support from Leo XIII, the 'Pope of the Rosary'."
