Legion of Mary
The Legion of Mary is a lay apostolic association of Catholics who, with the sanction of the Church and under the powerful leadership of Mary Immaculate, Mediatrix of All Graces, serve the Church and their neighbour on a voluntary basis in about 170 countries. The first meeting of the Legion of Mary took place in Myra House, Francis Street, Dublin, Ireland, on 7 September, 1921. This meeting was to have very beneficial consequences for the mission of the Catholic Church and, in a special way, for millions of members of Christ’s lay faithful who would serve in the Legion and for those who would be served by the legionary apostolate.
Drawing its inspiration from the True Devotion to Mary, as taught by St. Louis Marie de Montfort, and which had a profound influence on the Founder of the Legion, the Servant of God, Frank Duff, the Legion is at the disposal of the Bishops and Priests for use in the mission of the Church.
The basic unit of the Legion is called a praesidium, which is normally based in a parish.
