The Legion of Mary spirituality is based on St. Louis-Marie de Montfort’s true devotion to Mary. The Legion sees as its priority the spiritual and social welfare of each individual and is dedicated to bringing themselves and others closer to God through prayer and action.

Legionnaires perform a variety of duties, such as visiting the sick and shut-ins, making condolence calls, teaching religious education, and helping lax Catholics return to their faith. All this is done with a spiritual orientation. Auxiliary members are the praying wing of the Legion of Mary. They recite the Legion prayer and rosary daily. Active members meet weekly for 90 minutes on Tuesday mornings at 11:00 a.m. and all matters discussed are confidential.
