The Legion of Mary is a world-wide organization of the lay apostolate, in which Catholic men and women sanctify themselves through prayer and spiritual work in union with Our Lady under the guidance of the clergy.
A person can become either an "active member" or an "auxiliary" or "praying" member of the Legion of Mary.
Active members attend weekly meetings, pray the Catena (Legion Prayer) every day, and perform apostolic work during the week.
Auxiliary members do not pay dues and do not have to attend any meetings. They pray for the work of the active members of the Legion of Mary. They are invited to the annual consecration to Our Lady called the "Acies."
Legio Mariae is the main book of the Legion of Mary and is read at each of the meetings of the Legion of Mary.
