A brother. Originally a form of address in general use among the Christian faithful, as is clear from the frequent references to "brother" and "brethren" in the New Testament writings. Later the term came to be used more exclusively by members of religious orders, and finally, since the thirteenth century, it referred to those who belonged to one of the mendicant orders, mainly the Franciscans and Dominicans, although extended to others in the monastic tradition. Strictly speaking, however, a friar differs from a monk in that his ministry engages him in work outside the monastery, whereas traditionally the prayer and labors of a monk are identified within the monastery to which he belongs. (Etym. Old French frère, freire, brother; Latin frater, brother.)
