The Presbyterian Church in the United States grew out of regional and theological divisions within the Presbyterian Church in the United States of America (PCUSA), the first national Presbyterian denomination in the U.S. founded in 1789. In 1838, the PCUSA divided along theological lines due to the Old School–New School Controversy. The New School faction advocated revivalism and a softening of traditional Calvinism, while the Old School was opposed to the extremes of revivalism and desired strict conformity to the Westminster Confession, the Presbyterian Church's doctrinal standard. Many New School Presbyterians were also supportive of moral reform movements, such as abolitionism.
