Hospitallers

A celebrated brotherhood founded at various times and in different countries for the care of the sick in hospitals. The vow to devote themselves to this work of mercy is, in all these brotherhoods, superadded to the ordinary vows of poverty, chastity, and obedience, which are common to all the religious orders in the Roman Catholic Church. One of the earliest recorded instances of a hospital served by such a brotherhood is that of Con stance, in the 13th century. See Saint John of Jerusalem and Teutonic Knights .
