The Rule of Saint Augustine, written in about the year 400, is a brief document divided into eight chapters and serves as an outline for religious life lived in community. It is the oldest monastic rule in the Western Church.The rule, developed by Augustine of Hippo (354–430), governs chastity, poverty, obedience, detachment from the world, the apportionment of labour, the inferiors, fraternal charity, prayer in common, fasting and abstinence proportionate to the strength of the individual, care of the sick, silence and reading during meals. It came into use on a wide scale from the twelfth century onwards and continues to be employed today by many orders, including the Dominicans, Servites, Mercederians, Norbertines, and Augustinians.
