Soul liberty and the separation of church and state

Roger Williams, an English Puritan minister who emigrated to Massachusetts Bay Colony in 1631, developed the idea he called soul liberty, the conviction that civil government has no legitimate authority over matters of conscience and religious belief, and that requiring anyone to worship, or worship in a particular way, at the state's command corrupts true faith rather than protecting it. Williams put the claim memorably, writing that forced worship stinks in the nostrils of God. The position put him on a collision course with the Puritan authorities of Massachusetts Bay, who governed the colony as a religious commonwealth in which church membership and civil standing were closely bound together and dissent from the established faith carried real legal consequences. Williams also drew colonial authorities' anger by arguing that the English crown had no right to grant land already inhabited by Native peoples without fairly purchasing it from them, a position tied to the same underlying conviction that legitimate authority has limits the state cannot simply assume for itself. Massachusetts Bay banished Williams in 1635 for these views, and he fled south through the winter wilderness, eventually purchasing land from the Narragansett people and founding the settlement of Providence in 1636 as a colony where soul liberty would be the governing principle rather than a punishable offense.

Providence became a genuine experiment in what Williams's soul liberty actually meant in practice, a colony that welcomed religious dissenters of every kind, including Quakers and other groups persecuted elsewhere in New England, and that refused to establish any single church with state backing. Williams's own religious path continued evolving after founding the colony; he came to doubt aspects of the Puritanism he had left and, in 1639, helped establish what is generally recognized as the first Baptist church in North America, reflecting a Baptist emphasis on believer's baptism and voluntary church membership that fit naturally with his conviction that faith coerced by outside authority was not genuine faith at all. Rhode Island, the colony that grew out of Providence and Williams's other settlements, secured a royal charter in 1663 that formally protected liberty of conscience, making it one of the few colonies in British North America without an established church. Williams's writings, particularly his 1644 book The Bloudy Tenent of Persecution, argued the case for religious liberty at length and circulated well beyond Rhode Island's borders. Historians of American religious liberty generally trace a direct line from Williams's soul liberty through the later Baptist tradition's insistence on church-state separation to the First Amendment's religion clauses, though Williams himself acted a century before that constitutional language was written.
