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.
Many persons outside the Catholic Church would also benefit from that apostolate.
With the approval and support of the Popes and a great many Bishops, Priests and Religious, as well as the prayers and efforts of legionaries, the Legion, by the grace of God, has grown into a worldwide organisation with several million members.
