The object of the Legion of Mary is the glory of God through the holiness of its members developed by prayer and active co-operation in Mary’s and the Church’s work. The unit of the Legion of Mary is called a praesidium, which holds a weekly meeting, where prayer is intermingled with reports and discussion.
The Legion of Mary is a lay apostolic association of Catholics who, with the sanction of the Church and under the powerful leadership of our Blessed Mother, serve the Church and neighbor on a voluntary basis in about 170 countries.
