The main work of the Our Lady of Perpetaul Help Prasedium is to bring bringing Communion to the sick at the hospitals, nursing facilities or homes.
"The visitation of a hospital for the poor was the first work the Legion ever undertook and for a while it did no other. It teemed with blessings for the infant organisation, and the Legion desires that this work will ever be attended to by its praesidia. "
The Legion of Mary comprises active and auxiliary members. The latter recite prescribed legionary prayers. They constitute the praying wing of the organisation. Their prayers are offered not directly for the Legion but are presented as a gift to Our Lady. What wings are to the bird auxiliary members are to active legionaries.
