Notwithstanding the General Assembly's attempt to promote peace and unity, two distinct factions, the Old School and the New School, developed through the 1820s over the issues of confessional subscription, revivalism, and the spread of New England theology. The New School faction advocated revivalism and New England theology, while the Old School was opposed to the extremes of revivalism and desired strict conformity to the Westminster Confession. The ideological center of Old School Presbyterianism was Princeton Theological Seminary, which under the leadership of Archibald Alexander and Charles Hodge became associated with a brand of Reformed scholasticism known as Princeton Theology.
