Legion of Mary: What is Auxiliary Membership?
Auxiliary members pray the Rosary and the prayers of the Legion of Mary (the Tessera) for the intentions of the Blessed Mother and, in doing so, provide vital support through their prayers to the efforts of the active members.
The following two pamphlets include information about Auxiliary Membership and the rules for joining:
“A united, disciplined and coordinated body of all the Catholic forces, acting in dependence on the bishops. . . . It should be a great family of men and women, and boys and girls, moved by the one desire of sharing in the ministry of the Church and co-operating in the spreading of the Kingdom of Christ in individuals, in families, in society, a peaceful army of apostles eager to win souls to Christ and the Catholic Church . . . a single, compact, disciplined army.”
