Separation of church and state

The separation of church and state is a philosophical and jurisprudential concept for defining political distance in the relationship between religious organizations and the state. Conceptually, the term refers to the creation of a secular state (with or without legally explicit church-state separation) and to disestablishment, the changing of an existing, formal relationship between the church and the state. The concept originated among early Baptists in America. In 1644, Roger Williams, a Baptist minister and founder of the state of Rhode Island and the First Baptist Church in America, was the first public official to call for "a wall or hedge of separation" between "the wilderness of the world" and "the garden of the church." Although the concept is older, the exact phrase "separation of church and state" is derived from "wall of separation between Church & State," a term coined by Thomas Jefferson in his 1802 letter to members of the Danbury Baptist Association in the state of Connecticut. The concept was promoted by Enlightenment philosophers such as John Locke.

In a society, the degree of political separation between the church and the civil state is determined by the legal structures and prevalent legal views that define the proper relationship between organized religion and the state. The arm's length principle proposes a relationship wherein the two political entities interact as organizations each independent of the authority of the other. The strict application of the secular principle of laïcité is used in France. In contrast, societies such as Denmark and England maintain the constitutional recognition of an official state church; similarly, other countries have a policy of accommodationism, with religious symbols being present in the public square.

The philosophy of the separation of the church from the civil state parallels the philosophies of secularism, disestablishmentarianism, religious liberty, and religious pluralism. By way of these philosophies, the European states assumed some of the social roles of the church in form of the welfare state, a social shift that produced a culturally secular population and public sphere. In practice, church–state separation varies from total separation, mandated by the country's political constitution, as in India and Singapore, to a state religion, as in the Maldives.

The precise origin of the term itself dates to Jefferson and his correspondence with religious denominations, however, the entanglement of religion with government and the state dates back to antiquity when state and religion were often closely associated with one another.

The entanglement of religion with the state has a long history dating back at least to the prosecution and conviction to death of Socrates for impiety in ancient Athens.

An important contributor to the discussion concerning the proper relationship between Church and state was St. Augustine, who in The City of God, Book XIX, Chapter 17, examined the ideal relationship between the "earthly city" and the "city of God". In this work, Augustine posited that major points of overlap were to be found between the "earthly city" and the "city of God", especially as people need to live together and get along on earth. Thus, Augustine held, opposite to the separation of church and state, that it was the work of the "temporal city" to make it possible for a "heavenly city" to be established on earth.

For centuries, monarchs ruled by the idea of divine right. Sometimes this began to be used by a monarch to support the notion that the king ruled both his own kingdom and Church within its boundaries, a theory known as caesaropapism. On the other side was the Catholic doctrine that the Pope, as the Vicar of Christ on earth, should have the ultimate authority over the Church, and indirectly over the state, with the forged Donation of Constantine used to justify and assert the political authority of the papacy. This divine authority was explicitly contested by Kings, in the like of the, 1164, Constitutions of Clarendon, which asserted the supremacy of Royal courts over Clerical, and with Clergy subject to prosecution, as any other subject of the English Crown; or the 1215 Magna Carta that asserted the supremacy of Parliament and juries over the English Crown; both were condemned by the Vatican. Moreover, throughout the Middle Ages, the Pope claimed the right to depose the Catholic kings of Western Europe and tried to exercise it, sometimes successfully, e.g. 1066, Harold Godwinson, sometimes not, e.g., in 1305 with Robert the Bruce of Scotland, and later Henry VIII of England and Henry III of Navarre. The Waldensians were a medieval proto-Protestant group that urged separation of the Church from state.

In the West the issue of the separation of church and state during the medieval period centered on monarchs who ruled in the secular sphere but encroached on the Church's rule of the spiritual sphere. This unresolved contradiction in ultimate control of the Church led to power struggles and crises of leadership, notably in the Investiture Controversy, which was resolved in the Concordat of Worms in 1122. By this concordat, the Emperor renounced the right to invest ecclesiastics with ring and crosier, the symbols of their spiritual power, and guaranteed election by the canons of cathedral or abbey and free consecration.
