Benedictine Confederation in the context of "Rule of Saint Benedict"

The Benedictines, officially the Order of Saint Benedict (Latin: Ordo Sancti Benedicti, abbreviated as O.S.B. or OSB), are a mainly contemplative monastic order of the Catholic Church for men and for women who follow the Rule of Saint Benedict. Initiated in 529, they are the oldest of all the religious orders in the Latin Church. The male religious are also sometimes called the Black Monks, especially in English speaking countries, after the colour of their habits, although some, like the Olivetans, wear white. They were founded by Benedict of Nursia, a 6th-century Italian monk who laid the foundations of Benedictine monasticism through the formulation of his Rule. Benedict's sister Scholastica, possibly his twin, also became religious from an early age, but chose to live as a hermit. They retained a close relationship until her death.

Despite being called an order, the Benedictines do not operate under a single hierarchy. They are instead organized as a collection of autonomous monasteries and convents, some known as abbeys. The order is represented internationally by the Benedictine Confederation, an organization set up in 1893 to represent the order's shared interests. They do not have a superior general or motherhouse with universal jurisdiction but elect an Abbot Primate to represent themselves to the Vatican and to the world.

The Olivetans, formally known as the Order of Our Lady of Mount Olivet, are a monastic order. They were founded in 1313 and recognised in 1344. They use the Rule of Saint Benedict and are a member of the Benedictine Confederation, where they are also known as the Olivetan Congregation, but are distinguished from the Benedictines in their white habit and centralized organisation. They use the post-nominals 'OSB Oliv'.

The Abbot Primate of the Order of St. Benedict serves as the elected representative of the Benedictine Confederation of monasteries in the Catholic Church. While normally possessing no authority over individual autonomous monasteries or congregations, he does serve as a liaison to the Vatican on behalf of the Benedictines, promotes unity among Benedictine monasteries and congregations, and represents Benedictines at religious gatherings throughout the world. He resides in Rome, Italy, at the Abbey of Sant'Anselmo all'Aventino which serves, because he is Abbot Primate, as the "Primatial Abbey of Sant'Anselmo." He appoints a Rector to oversee the College of Sant'Anselmo, serves as the "Grand Chancellor" of the Pontificio Ateneo Sant'Anselmo, and appoints a Rector to oversee the Church of Sant'Anselmo.

The Abbey of Saint Scholastica, also known as Subiaco Abbey (Italian: Abbazia di Santa Scolastica), is located just outside the town of Subiaco in the Province of Rome, Region of Lazio, Italy; and is still an active Benedictine abbey, territorial abbey, first founded in the 6th century AD by Saint Benedict of Nursia. It was in one of the Subiaco caves (or grotto) that Benedict made his first hermitage. The monastery today gives its name to the Subiaco Congregation, a grouping of monasteries worldwide that makes up part of the Order of Saint Benedict.

St. Scholastica's Abbey today is part of the Subiaco Congregation, a grouping of 64 male Benedictine monasteries on five continents, to which 45 female monasteries also belong, within the larger Benedictine Confederation.
