monk

A term often applied to any man in a religious order, it should be restricted to members of contemplative orders, such as Benedictines, Cistercians and Carthusians. Friar is the name given to members of the mendicant orders, such as the Dominicans, Franciscans, Augustinians and Carmelites, which are pledged to live on free-will offerings. Brother is a title given to laymen who take vows as members of religious communities. Monks and friars can be, but often are not, ordained priests. Brothers remain in the lay state but as vowed members of the community. All monks, friars and brothers who are not ordained can be addressed as Brother in conversation and on first reference, such as Brother John Doe. On second reference, continue to use Brother and the first name if the person is known that way, such as Brother John. Otherwise, use only the last name on second reference.
