O Mary, conceived without sin.
Pray for us who have recourse to you.
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 neighbor on a voluntary basis in about 170 countries. 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.
