The Order of St. Benedict is a Roman Catholic religious order of independent monastic communities that observe the Rule of St. Benedict. Within the order, each individual community maintains its own autonomy, while the organization as a whole exists to represent their mutual interests. Today the terms “Order of St. Benedict” and “Benedictine Order” are also used frequently to refer to the total of the independent Benedictine abbeys, thereby giving the wrong impression of a “generalate” or “motherhouse” with jurisdiction over dependent communities. The Benedictine Confederation, which was established in 1883 by Pope Leo XIII in his brief Summum semper, is the international governing body of the order, headed by the Abbot Primate.

The monastery at Subiaco established in Italy by St. Benedict of Nursia circa 529 was the first of a dozen monasteries founded by him. Even so, there is no evidence to suggest that he intended to found an order. To the contrary, the Rule of St Benedict presupposes the autonomy of each community. Despite the absence of a Benedictine order, since most monasteries founded during the Middle Ages adopted the Rule of St Benedict, it became the standard for Western Monasticism.

Even today Benedictine monasticism is fundamentally different from other Western religious orders insofar as its individual communities are not part of a religious order with “Generalates” and “Superiors General”. Rather, in modern times, the various autonomous houses have formed themselves loosely into congregations (for example, Cassinese, English, Solesmes, Subiaco, Camaldolese, Sylvestrines) that in turn are represented in the Benedictine Confederation that came into existence through Pope Leo XIII’s Apostolic Brief “Summum semper” on July 12, 1883. This organization facilitates dialogue of Benedictine communities with each other and the relationship between Benedictine communities and other religious orders and the church at large.
