Saint Louis-Marie Grignion de Montfort (31 January 1673 - 28 April 1716) was a French Roman Catholic priest and Confessor. He was known in his time as a preacher and was made a missionary apostolic by Pope Clement XI. As well as preaching, Montfort found time to write a number of books which went on to become classic Catholic titles and influenced several popes. Montfort is known for his particular devotion to the Blessed Virgin Mary and the practice of consistently praying the Rosary. Montfort is considered as one of the early Marian proponents of the field of Mariology as it is known today, and a viable candidate to become a Doctor of the Church. His most notable works regarding Marian devotions are contained in The Secret of Mary and the True Devotion to Mary. The Roman Catholic Church, under the pontificate of Pope Pius XII canonized Montfort on July 20, 1947. A "founders statue" created by Giacomo Parisini is currently placed at the upper niche of the south nave of Saint Peter's Basilica at the Vatican. The paper consists of St. Louis Marie de Montfort. For some, "The Love of Eternal Wisdom" is believed to be the key to the whole thought of the saint. St. Louis Marie de Montfort saint describes how you can achieve spiritual union with Jesus Christ.
