St. Paul Praesidium of the Legion of Mary strives to give Christ to the world through the union of our Blessed Mother, Mary, who makes them holy, then converts souls through her members, by means of the Holy Spirit. This self sanctification and the sanctification of others is accomplished by prayers and good works, at the disposal of the Bishop of our Dioceses and the Parish pastor for any form of social service and Catholic Action.

Duties include prescribed prayers, self-sacrifice and weekly attendance of meetings.
