Reformed/Presbyterian churches are a Protestant tradition based on the teachings of reformer John Calvin. The Reformed tradition consists both of Presbyterian churches as well as denominations that developed in continental Europe, such as the Dutch and the German Reformed. American Presbyterianism split over revivalism, slavery, and fundamentalism, but is still one of the leading Protestant families in the United States. Presbyterian bodies include Presbyterian Church (U.S.A.) and Presbyterian Church in America.
