Written in 1712 by Saint Louis de Montfort, this influential Catholic treatise remained virtually unknown until it was discovered in France in 1842. Finally published in 1843 in its original French, the work became an instant success and would later have a profound impact on many Catholic popes. Pope John Paul II, a most devout believer in the importance of the Blessed Virgin Mary, said reading "True Devotion to Mary" was a "decisive turning point" in his life. Montfort believed that the easiest and most perfect path to Jesus Christ lay in worship of the Blessed Virgin Mary. Through devout dedication to Mary, one could find salvation and eternal life with Jesus Christ. By praising, loving and honoring Mary, one was truly loving and honoring God and Jesus Christ. This devotion to Mary was the most pure and true devotion, showed a profound love and commitment to Jesus Christ, and would bring about wonderful spiritual effects in the worshipper. The greatest book on Marian spirituality ever written, "True Devotion to Mary" continues to inspire and guide the faithful to this day. This edition is printed on premium acid-free paper.
