 In important respects, this is a more radical theory than the (much more popular and influential) one developed by Locke, who distinguishes between state and church in an early liberal perspective of natural individual rights. While it is the duty of the state to secure the “civil interests” of its citizens, the “care of the soul” cannot be its business, this being a matter between the individual and God to whom alone one is responsible in this regard. Hence there is a God-given, inalienable right to the free exercise of religion. Churches are no more than voluntary associations without any right to use force within a legitimate political order based on the consent of the governed. Locke draws the limits of toleration where a religion does not accept its proper place in civil society (such as Catholicism, in Locke’s eyes) as well as where atheists deny any higher moral authority and therefore destroy the basis of social order.
