The "Rule of Saint Augustine" is a set of guidelines for monastic life, attributed to Saint Augustine of Hippo, a Christian theologian and philosopher. Written in the 5th century, it emphasizes community living, prayer, and the importance of love and charity among members. The rule encourages monks to live in harmony, sharing their possessions and supporting one another in their spiritual journey. This rule has influenced many religious communities, particularly within the Augustinian order and other Christian monastic traditions. It serves as a foundation for communal life, focusing on the balance between individual spirituality and collective responsibility.
