The title, Rule of Saint Augustine, has been applied to each of the following documents: • Letter 211 addressed to a community of women; • Sermons 355 and 356 entitled "
De vitâ et moribus clericorum suorum"; • a portion of the rule drawn up for clerks or
Consortia monachorum; • a rule known as
Regula secunda; and • another rule called: "
De vitâ eremiticâ ad sororem liber". The last is a treatise on eremitical life by Saint Ælred, Abbot of Rievaulx, England, who died in 1166. The two preceding rules are of unknown authorship. Letter 211 and Sermons 355 and 356 were written by Augustine.
Letter 211 Saint Augustine wrote this letter in 423 to the nuns in a monastery at
Hippo that had been governed by his sister and in which his cousin and niece lived. Though he wrote chiefly to quiet troubles incident to the nomination of a new superior, Augustine took the opportunity to discuss some of the virtues and practices essential to religious life as he understood it: he emphasised such considerations as charity, poverty, obedience, detachment from the world, the apportionment of labour, the mutual duties of superiors and 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.
De opere monachorum Bishop
Aurelius of Carthage was greatly disturbed by the conduct of monks who indulged in idleness under pretext of contemplation, and at his request St. Augustine published a treatise entitled
De opere monachorum wherein he proves by the authority of the Bible, the example of the Apostles, and even the exigencies of life, that the monk is obliged to devote himself to serious labour. In several of his letters and sermons is found a useful complement to his teaching on the monastic life and duties it imposes. In his treatise,
De opere monachorum, he inculcates the necessity of labour, without, however, subjecting it to any rule, the gaining of one's livelihood rendering it indispensable. Monks of course, devoted to the ecclesiastical ministry observe, ipso facto, the precept of labour, from which observance the infirm are legitimately dispensed. These, then, are the most important monastic prescriptions found in the rule of and writings of Saint Augustine.
