Catholic religious orders ('Religious Institutes', cf. canons 573-746) are the major form of consecrated life in the Roman 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. They do so for the purpose of imitating Jesus of Nazareth more closely, mainly but not exclusively (for every order has also its peculiar charism) by observing evangelical chastity, poverty and obedience, which are the three evangelical counsels of perfection (cf. canons 599-601). They bind themselves in Church Law to this form of Christian living by taking public vows. They may additionally profess to obey certain guidelines for living. Vows are to be distinguished from Holy Orders, the sacrament which bishops, priests and deacons receive, and thus religious are not members of the hierarchy.
There are two basic types of Catholic religious orders: congregations, which take simple vows (e.g. the Congregation of Holy Cross), and orders proper, which take solemn vows (for example, the Society of Jesus) but the term congregation sometimes also applies to branches of an order which historically united several ones and/or was extended with one or more branches of a different kind, such as for women in addition to the pre-existing one for men, or tertiaries.
A number of generic terms exist to define groups of orders and congregations, but they are not always exclusively defined. These include Mendicant orders, Canons regular, etc. As well particular or familiar names exist for religious such as Brother and Sister, whereas older terms including Mother and Nun are now more infrequently used. Technically Nuns are religious women who profess solemn vows rather than simple vows.
One of the oldest guides for religious life was written by St Augustine of Hippo, who stressed self-denial, moderation, and care for those in need.
[edit] List of Roman Catholic religious institutes
The following list refers to some of the major religious institutes of the Catholic Church, both orders and others; it should be understood that communities using the same name may exist in Anglican or Eastern Orthodox traditions as well, as well as more than one Catholic order with the same name. Each is accompanied by its official name in English as well as the acronym (or "post-nominal initials") commonly used to identify its members. In many cases name variations and/or alternative names are also in use. In parentheses is the year it was established and the number of members, if known.
