In theCatholic Church, areligious order is a community ofconsecrated life with members who professsolemn vows. They are classed as a type ofreligious institute.[1]
Subcategories ofreligious orders are:
Catholic religious orders began as early as the 500s, with theOrder of Saint Benedict being formed in 529. The earliest orders include theCistercians (1098), thePremonstratensians (1120), thePoor Clares founded byFrancis of Assisi (1212), and the Benedictine reform movements ofCluny (1216). These orders were confederations of independent abbeys and priories, who were unified through a loose structure of leadership and oversight.
Later the mendicant orders such as theCarmelites, theOrder of Friars Minor, theOrder of Preachers, theOrder of the Most Holy Trinity and theOrder of Saint Augustine formed. These Mendicant orders did not hold property for their religious communities, instead begging for alms and going where they were needed. Their leadership structure included each member, as opposed to each abbey or house, as subject to their direct superior.
In the past, what distinguished religious orders from other institutes was the classification of thevows that the members took as solemn vows. According to this criterion, the last religious order founded was that of theBethlehemite Brothers in 1673.[2] Nevertheless, in the course of the 20th century, some religious institutes outside the category of orders obtained permission to make solemn vows, at least of poverty, thus blurring the distinction.[citation needed]
Solemn vows were originally considered indissoluble. As noted below, dispensations began to be granted in later times, but originally not even the Pope could dispense from them.[3] If for a just cause a member of a religious order was expelled, the vow of chastity remained unchanged and so rendered invalid any attempt at marriage, the vow of obedience obliged in relation, generally, to the bishop rather than to the religious superior, and the vow of poverty was modified to meet the new situation but the expelled religious "could not, for example, will any goods to another; and goods which came to him reverted at his death to his institute or to the Holy See."[4]
The former1917 Code of Canon Law reserved the termreligious order for institutes in which the vows were solemn, and used the termreligious congregation (or simply congregation) for institutes withsimple vows. The members of a religious order for men were called regulars, those belonging to a religious congregation were simplyreligious, a term that applied also to regulars. For women, those with simple vows were calledreligious sisters, with the termnun reserved in canon law for those who belonged to an institute of solemn vows, even if in some localities they were allowed to take simple vows instead.[5]

However, it abolished the distinction according to which solemn vows, unlike simple vows, were indissoluble. It recognized no totally indispensable religious vows and thereby abrogated for theLatin Church the special consecration that distinguished orders from congregations, while keeping some juridical distinctions.[4]
In practice, even before 1917 dispensations from solemn religious vows were being obtained by grant of the Pope himself, while departments of the Holy See and superiors specially delegated by it could dispense from simple religious vows.[6]
The 1917 Code maintained a juridical distinction by declaring invalid any marriage attempted by solemnly professed religious or by those with simple vows to which the Holy See had attached the effect of invalidating marriage,[7] while stating that no simple vow rendered a marriage invalid, except in the cases in which theHoly See directed otherwise.[8] Thus members of orders were barred absolutely from marriage, and any marriage they attempted was invalid. Those who made simple vows were obliged not to marry, but if they did break their vow, the marriage was considered valid.
Another difference was that a professed religious of solemn vows lost the right to own property and the capacity to acquire temporal goods for themselves, but a professed religious of simple vows, while being prohibited by the vow of poverty from using and administering property, kept ownership and the right to acquire more, unless the constitutions of the religious institute explicitly stated the contrary.[9]
After publication of the 1917 Code, many institutes with simple vows appealed to the Holy See for permission to make solemn vows. The Apostolic ConstitutionSponsa Christi of 21 November 1950 made access to that permission easier for nuns (in the strict sense), though not for religious institutes dedicated to apostolic activity. Many of these latter institutes of women then petitioned for the solemn vow of poverty alone. Towards the end of theSecond Vatican Council, superiors general of clerical institutes and abbots president of monastic congregations were authorized to permit, for a just cause, their subjects of simple vows who made a reasonable request to renounce their property except for what would be required for their sustenance if they were to depart.[10] These changes resulted in a further blurring of the previously clear distinction between orders and congregations, since institutes that were founded as congregations began to have some members who had all three solemn vows or had members that took a solemn vow of poverty and simple vows of chastity and obedience.[citation needed]
The current1983 Code of Canon Law maintains the distinction between solemn and simple vows,[11] but no longer makes any distinction between their juridical effects, including the distinction between orders and congregations. Instead, it uses the single termreligious institute to designate all such institutes.[12][13]
While solemn vows once meant those taken in what was called a religious order, "today, in order to know when a vow is solemn it will be necessary to refer to the proper law of theinstitutes of consecrated life."[14]
TheAnnuario Pontificio continues to distinguish betweenOrdini (Orders) andCongregazioni Religiose Clericali (Clerical Religious Congregations). Some other authors use the terms religious order and religious institute as synonyms; canon lawyer Nicholas Cafardi, commenting on the fact that thecanonical term is religious institute, write that religious order is a colloquialism.[15]

A religious order is characterized by an authority structure where asuperior general has jurisdiction over the order's dependent communities. An exception is theOrder of Saint Benedict which is not a religious order in this technical sense, because it has a system of independent houses, meaning that each abbey is autonomous. However, the constitutions governing the order's global independent houses and its distinct Benedictine congregations (of which there are twenty) were approved by the pope. Likewise, according to rank and authority, theabbot primate's "position with regard to the other abbots [throughout the world] is to be understood rather from the analogy of a primate in a hierarchy than from that of the general of an order like theDominicans and theJesuits."[16]
The Canons Regular of Saint Augustine are in a situation similar to that of the Benedictines. They are organized in eight congregations, each headed by an abbot general, but also have an Abbot Primate of the Confederated Canons Regular of Saint Augustine. And the Cistercians are in thirteen congregations, each headed by an abbot general or an abbot president, but do not use the title of abbot primate.




TheAnnuario Pontificio presents the list of male religious institutes in anElenco Storio-Giuridico di Precedenza ("Historical-juridical list of precedence"). This list gives priority to certain types of institutes: Orders (divided into Canons Regular, monastics, mendicant orders, clerics regular), clerical religious congregations, lay religious congregations, Eastern religious congregations,secular institutes,societies of apostolic life.[17] The list is found in the 1964 edition of theAnnuario Pontificio, pp. 807–870, where the heading is "States of Perfection (of pontifical right for men)". In the 1969 edition the heading is "Religious and Secular institutes of Pontifical Right for Men", a form it kept until 1975. Since 1976, when work was already advanced on revising the Code of Canon Law, the list has been qualified as "historical-juridical".

The list of religious institutes for women in theAnnuario Pontificio does not distinguish between orders (with solemn vows) and congregations (with simple vows). Many of the religious orders for men listed above have comparable religious institutes for women with solemn vows.
