congregatio

Congregatio is a Latin noun meaning an assembly or gathering, and it is the root of the English term congregation. In ecclesiastical Latin it designates an official body within the Church charged with a particular area of governance or discipline. The verb from which it derives, congregare, means to bring together.

In the Roman Catholic Church, a Congregation is a major department of the Roman Curia responsible for a broad area of governance. Traditionally led by a cardinal prefect with a secretary and staffed by prelates and officials, Congregations issue norms, oversee administrative matters, and handle specific questions within their competence. Well-known examples include the Congregation for the Doctrine of the Faith, which handles doctrinal issues; the Congregation for the Evangelization of Peoples, which oversees missionary activity and jurisdiction in mission territories; the Congregation for the Causes of Saints, which directs processes for canonization; and the Congregation for the Clergy, which oversees matters pertaining to priests and parishes. Other Congregations address the Institutes of Consecrated Life and Societies of Apostolic Life, or matters related to liturgy and sacraments. In recent years the Vatican has reorganized certain functions under the broader umbrella of dicasteries, but the Latin designation Congregatio continues to appear in official titles and historical references.

Outside the Vatican, the term Congregation also denotes a local church community within many Christian traditions, or a religious community such as a convent or monastery. In secular usage, it can refer to any association or group gathered for a common purpose. The word thus spans both formal ecclesiastical bodies and general meanings of a gathered community.
