Religious order

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. The order is composed of initiates (laity) and, in some traditions, ordained clergy. Religious orders exist in many of the world's religions.

In Buddhist societies, a religious order is one of the number of monastic orders of monks and nuns, many of which follow under a different school of teaching, such as Zen. A well-known Chinese Buddhist order is the ancient Shaolin order in Ch'an (Zen) Buddhism and in modern times the Order of Hsu Yun.

A Catholic religious institute is a society whose members (referred to as "religious") pronounce vows that are accepted by a superior in the name of the Church and who live a life of brothers or sisters in common.Catholic religious orders and congregations are the two historical categories of Catholic religious institutes. Religious institutes are distinct from secular institutes, another kind of institute of consecrated life, and from lay ecclesial movements.

In the Catholic Church, members of religious institutes, unless they are also deacons or priests in Holy Orders, are not clergy, but belong to the laity. While the state of consecrated life is neither clerical or lay, institutes themselves are classified as one or the other, a clerical institute being one that "by reason of the purpose or design intended by the founder or by virtue of legitimate tradition, is under the direction of clerics, assumes the exercise of sacred orders, and is recognized as such by the authority of the Church".
