Italian monk Saint Benedict of Nursia, considered the patriarch of western monasticism, founded the Benedictine order circa 529. The Catholics and the Anglican Church honor this Christian patron of Europe and students. With 12 communities at Subiaco, forty miles to the east of Rome, he moved to Monte Cassino in the southern mountains. The mere confederation of autonomous congregations, not commonly understood, originated later. His main achievement, his "Rule of Saint Benedict," contains precepts. The writings of John Cassian heavily influences this book, which shows strong affinity with the Rule of the Master. This unique spirit of balance, moderation, and reasonableness (ἐπιείκεια, epieikeia) persuaded most religious communities, founded throughout the Middle Ages, to adopt it. As a result, his Rule most influences religious rules in Christendom.
