John Wesley founder of Methodism and hertic in his day.
"And for his own part, Wesley flouted many regulations of the Church of England concerning parish boundaries and who had authority to preach. This was seen as a social threat that disregarded institutions. Ministers attacked them in sermons and in print, and at times mobs attacked them. Wesley and his followers continued to work among the neglected and needy. They were denounced as promulgators of strange doctrines, fomenters of religious disturbances; as blind fanatics, leading people astray, claiming miraculous gifts, attacking the clergy of the Church of England, and trying to re-establish Catholicism.” - Wikipedia
