One of the main Protestant groups that arose out of the 16th-century Reformation. Generally speaking, modern Presbyterian churches trace their origins to the Calvinist churches of the British Isles, the European counterparts of which came to be known by the more inclusive name of Reformed. The term presbyterian also denotes a collegiate type of church government led by pastors and lay leaders called elders or presbyters. Strictly speaking, all Presbyterian churches are a part of the Reformed, or Calvinist, tradition, although not all Reformed churches are presbyterian in their form of government.
