A Roman Chatholic Religous order, The Order of Saint Benedict, observes the the Rule of Saint Benedict. Within the order, each individual community (which may be a monastery, a priory or abbey) maintains its own autonomy, while the organization as a whole exists to represent their mutual interests.
The Rule of Saint Benedict requires candidates for reception into a Benedictine community to promise solemnly stability (to remain in the same monastery), conversatio morum (an idiomatic Latin phrase suggesting "conversion of manners"), and obedience (to the superior, because the superior holds the place of Christ in their community). This solemn commitment tends to be referred to as the "Benedictine vow" and is the Benedictine antecedent and equivalent of the evangelical counsels professed by candidates for reception into a religious order.
