A religious order is a lineage of communities and organizations of people who live in some way set apart from society in accordance with their specific religious devotion, usually characterized by the principles of its founder’s religious practice. They follow a form of consecrated life in the Roman Catholic Church. They do so for the purpose of imitating Jesus more closely, mainly but not exclusively by observing evangelical chastity, poverty and obedience, which are the three evangelical counsels of perfection. A Religious Order is characterized by an authority structure where a Superior General has jurisdiction over the order’s dependent communities. Pontifical Council Cor Unum is the dicastery (Department) responsible for coordinating the charitable activities of the Catholic Church.
There are two principal types of Catholic religious orders. Members of congregations (such as the Congregation of Holy Cross) take simple vows, while members of orders proper (such as the Society of Jesus) take solemn vows. The term congregation sometimes also applies to branches of an order such as for women in addition to the pre-existing one for men, or tertiaries. Additionally, a number of generic terms, which are not always exclusively defined, exist to define groups of orders and congregations, such as mendicant orders or canons regular. As well particular or familiar names exist for religious such as Brother and Sister, whereas older terms including Monk and Nun are now more infrequently used. Technically Nuns are religious women who profess solemn vows rather than simple vows.
The religious orders could be Contemplative orders” (such as Benedictines, Carmelites, Trappists, Carthusians, Cistercians, etc.) are those who primarily focus is to grow in union with God for the love of God and the salvation souls. Such communities typically have little interaction with society. “Active” orders (Franciscans, Dominicans, Missionaries of Charity, etc.) are those who tend to have more direct interaction with the world than contemplative orders. While still principally prayer-centered, active orders generally dedicate more time to certain apostolates, such as feeding the hungry, teaching, preaching, missions, youth retreats, and various forms of service to the community.
