A church (or local church) is a religious organization or congregation that meets in a particular location. Many are formally organized, with constitutions and by-laws, maintain offices, are served by clergy or lay leaders, and, in nations where this is permissible, often seek non-profit corporate status. Local churches often relate with, affiliate with, or consider themselves to be constitutive parts of denominations, which are also called churches in many traditions. Depending on the tradition, these organizations may connect local churches to larger church traditions, ordain and defrock clergy, define terms of membership and exercise church discipline, and have organizations for cooperative ministry such as educational institutions and missionary societies. Non-denominational churches are not part of denominations, but may consider themselves part of larger church movements without institutional expression. The word church may also be used for other religious communities, although for non-Christian communities the term is sometimes considered archaic or even offensive, while some other non-Christian communities themselves use the word to refer to their community or house of worship. History The word church is used in the sense of a distinct congregation in a given city in slightly under half of the 200 uses of the term in the New Testament. John Locke defined a church as "a voluntary society of men, joining themselves together of their own accord in order to the public worshipping of God in such manner as they judge acceptable to him". A local church may be run using congregationalist polity and may be associated with other similar congregations in a denomination or convention, as are the churches of the Southern Baptist Convention or like German or Swiss Landeskirchen. It may be united with other congregations under the oversight of a council of pastors as are Presbyterian churches. It may be united with other parishes under the oversight of bishops, as are Anglican, Lutheran, Oriental Orthodox, and Eastern Orthodox churches. Finally, the local church may function as the lowest subdivision in a global hierarchy under the leadership of one bishop, such as the pope (the bishop of Rome) of the Roman Catholic Church. Such association or unity is a church's ecclesiastical polity. Etymology The Greek word ekklēsia, literally "called out" or "called forth" and commonly used to indicate a group of individuals called to gather for some function, in particular an assembly of the citizens of a city, as in , is the New Testament
