Baptists in the history of separation of church and state

Separation of church and state is one of the primary theological distinctions of the Baptist tradition.

Originally, Baptists supported separation of church and state in England and America. Some important Baptist figures in the struggle were John Smyth, Thomas Helwys, Edward Wightman, Leonard Busher, Roger Williams (who was a Baptist for a short period but became a "Seeker"), John Clarke, Isaac Backus, and John Leland.

In 1612 John Smyth wrote, "the magistrate is not by virtue of his office to meddle with religion, or matters of conscience". That same year, Thomas Helwys wrote that the King of England could "command what of man he will, and we are to obey it," but, concerning the church—"with this Kingdom, our lord the King hath nothing to do." In 1614, Leonard Busher wrote what is believed to be the earliest Baptist treatise dealing exclusively with the subject of religious liberty.

The Danbury Baptist Association of Danbury, Connecticut sent a letter, dated October 7, 1801, to the newly elected President Thomas Jefferson, expressing concern over the lack in their state constitution of explicit protection of religious liberty, and against a government establishment of religion.

In their letter to the President, the Danbury Baptists affirmed that "Our Sentiments are uniformly on the side of Religious Liberty":

The address of the Danbury Baptist Association in the State of Connecticut, assembled October 7, 1801.

To Thomas Jefferson, Esq., President of the United States of America

Sir, Among the many millions in America and Europe who rejoice in your election to office, we embrace the first opportunity which we have enjoyed in our collective capacity, since your inauguration, to express our great satisfaction in your appointment to the Chief Magistracy in the United States. And though the mode of expression may be less courtly and pompous than what many others clothe their addresses with, we beg you, sir, to believe, that none is more sincere.
