Basilian monks are monks who follow the "Rule" of Saint Basil the Great, bishop of Caesarea (330-379). The monastic rules and institutes of St. Basil are important because their reconstruction of monastic life remains the basis for most Eastern Orthodox and some Greek Catholic monasticism. Saint Benedict of Nursia, who fulfilled much the same function in the West, took his Regula Benedicti from the writings of St. Basil and other earlier church fathers. In the Eastern Orthodox Church, monks do not generally call themselves "Basilians", while the Greek Catholics do. Thus the expression "Basilian monk" almost always refers to religious of those Eastern Catholic Churches which follow the Byzantine Rite.
