Presbyterian minister George Duffield IV (1794-1868) in Detroit, Michigan, at the behest of his congregation, confronted the local Episcopal Bishop over a sermon that he had preached arguing for Episcopal Government and Apostolic Succession. In 1842, Duffield, in a series of letters, addressed the Bishop, and challenged him on Episcopal Government. For students of polity, or those with an interest in Presbyterian church government, Rev. George Duffield’s work against Episcopacy showcases a debate in an American context and would prove helpful to anyone studying the subject.
