The term Cistercian is used to refer to an order of Roman Catholic monks. Officially the order is called "Ordo Cisterciensis" ("OCist"), or "Sacer Ordo Cisterciensis" ("SOC"). These people follow the same rules as the Benedictines, that is to say those of St Benedict. Over time, the Benedictines made some changes to the rules and the way of life.
