Saint Louis-Marie Grignion de Montfort was born in Brittany, France on January 31, 1673. He was ordained to the priesthood in 1700 and distinguished himself by his zeal and missionary work. He preached so forcefully and effectively against the errors of Jansenism that he was expelled from several dioceses in France. He took his case to Rome, were Pope Clement XI Conferred on him the title of Missionary Apostolic, enabling him to continue his apostolate. An ardent devotee of Our Lady, he preached Mary everywhere. In his Treatise on True Devotion to Marry he fervently advocates the path taken by the God-man for our redemption as our path to holiness. "To Jesus through Mary" became his motto and total consecration as slaves of love to Mary became his means. His inspiring work, The Secret of the Rosay, cemented his legacy as one of its greatest apostles. Sain Louis also founded the congregation of the daughters of Divine Wisdom and a missionary order known as the Company of Mary. He died on April 28, 1716, at Saint-Laurent-Sur-Sevre, France. He was forty-three. His las words were: "I am all Thine, and all I have is Thine, O most loving Jesus, through Mary, Thy Holy Mother." He was Marian to the last. Pope Pius XII canonized the "Apostle of Mary" in 1917. The cause for his declaration as Docter of the Church is no in progress.
