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 and 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.
