The First Experiments in Freedom of Belief and Religious Tolerance in America

Religious Freedom:  The First Experiments in Freedom of Belief and Religious Tolerance in America were based on the Bible and changed History

While the idea of freedom of conscience—freedom of belief and conviction—was advanced by the Reformation and existed in Europe in the 1500s and 1600s, it was not embraced by everyone and was very restricted in actual practice, manifesting in only partial, contested, temporary ways.  However, the Bible-based arguments made for it by reformers like Martin Luther and John Calvin were quite similar to those later made by individuals who directly impacted American thought and settlement in the 1600s and 1700s.

American Puritan dissenter Roger Williams, Quaker William Penn, Catholic colonizer Cecil Calvert, and British philosopher John Locke played important roles in advancing freedom of conscience and religious tolerance in America during this time.  Their arguments for freedom of belief and religious tolerance were strongly rooted in the Bible.  Their tolerance writings and colonies would significantly influence future views and practices in England and America.

Williams, Penn, Calvert, and Locke would be the first movers to defend and experiment with greater freedom of belief and religious tolerance in America.  Their first experiments in religious tolerance took place in the colonies of Rhode Island, Pennsylvania, Maryland, and Carolina:

Based on conviction, these movers attempted to practice and experiment with freedom of belief and tolerance by forming new, tolerant colonies.  Their experiments were notable and real, if imperfect and incomplete, testimonies for the world in this largely unpracticed idea.  These colonizers and colonies brought the issue of freedom of conscience to the forefront of the American mind.

America’s unique, free environment and new colonies made such experiments feasible.  According to Gary Amos and Richard Gardiner in their text, Never Before in History: America’s Inspired Birth, “The Protestant Reformation in Europe and in the American colonies forced people to reexamine the traditional merger between church and government.  America in particular was to become the test case for resolving the tension between religious freedom and social conformity.”  The arguments for and experiments in freedom of belief and religious tolerance in America significantly advanced American and Western thought and practice on this issue and laid the groundwork for future religious freedom in the United States.
