The Radical Reformation was a movement in the 16th century that sought to reform Christianity beyond the changes initiated by the Protestant Reformation. Unlike mainstream reformers like Martin Luther and John Calvin, radical reformers advocated for a more profound break from traditional practices and beliefs, emphasizing personal faith and the authority of Scripture. Key groups within the Radical Reformation included the Anabaptists, who rejected infant baptism and promoted adult baptism based on personal conviction. They also emphasized the separation of church and state, advocating for a community of believers living according to their interpretation of the Bible.
