4 Notable Independents and Congregationalists

Origins
Many Congregational churches trace their descent from the original Congregational Church, a family of Protestant denominations formed on a theory of union published by the theologian Robert Browne in 1592 and arising from the Nonconformist religious movement in England during the Puritan reformation. In Great Britain, the early congregationalists were called separatists or independents to distinguish themselves from the similarly Calvinistic Presbyterians, and some congregationalists there still call themselves "Independents".

There are difficulties in identifying a specific beginning because Congregationalism is more easily identified as a movement than a single denomination, given its distinguishing commitment to the complete autonomy of the local congregation. The idea that each distinct congregation fully constitutes the visible Church can, however, be traced to John Wyclif and the Lollard movement which followed after Wyclif was removed from teaching authority in the Roman Catholic Church.

The early Congregationalists shared with Anabaptist theology the ideal of a pure church, which made adult conversion experience important for full membership in the church, unlike other Reformed churches. As such, the Congregationalists were a reciprocal influence on the Baptists, differing from them in that they counted the children of believers in some sense members of the church unlike the Baptists, because of baptism.
