Benedictines

The Benedictines, officially the Order of Saint Benedict (, 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 a 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.

In some regions, Benedictine nuns are given the title Dame in preference to Sister. Provided by Wikipedia
