Religious orders (''Religious Institutes'', cf. canons 573 746) are the major form of consecrated life in the Catholic Church. They are organizations of laity and/or clergy who live a common life following a religious rule under the leadership of a religious superior. Two of these[which?] are enclosed monastic orders, others are not. Their intention is to imitate Jesus more closely, mainly, but not exclusively by observing evangelical chastity, poverty and obedience, which are the three evangelical counsels of perfection (cf. canons 599 601). They bind themselves to this form of living by taking public vows in accordance with the norms of church law. They may additionally profess to obey certain guidelines for living, since each order has its peculiar charism.
