that regeneration occurred in stages. In 1738, the synod moved to restrict itinerant preaching and to tighten educational requirements for ministers, actions the New Side resented. Tensions between the two sides continued to escalate until the Synod of May 1741, which ended with a definite split between the two factions. The Old Side retained control of the Synod of Philadelphia, and it immediately required unconditional subscription to the Westminster Confession with no option to state scruples. The New Side founded the Synod of New York. The new Synod required subscription to the Westminster Confession in accordance with the Adopting Act, but no college degrees were required for ordination. While the controversy raged, American Presbyterians were also concerned with expanding their influence. In 1740, a New York Board of the Society in Scotland for the Propagation of Christian Knowledge was established. Four years later, David Brainerd was assigned as a missionary to the Native Americans. New Side Presbyterians were responsible for founding Princeton University (originally the College of New Jersey) primarily to train ministers in 1746. By 1758, both sides were ready for reconciliation. Over the years, New Side revivalism had become less radical. At the same time, Old Side Presbyterians were experiencing numerical decline and were eager to share in the New Side's vitality and growth. The two synods merged to become the Synod of New York and Philadelphia. The united Synod was founded on New Side terms: subscription according to the terms of the Adopting Act; presbyteries were responsible for examining and licensing ordination candidates; candidates were to be examined for learning, orthodoxy and their "experimental acquaintance with religion" (i.e. their personal conversion experiences); and revivals were acknowledged as a work of God. American Independence (1770–1789) In the early 1770s, American Presbyterians were initially reluctant to support American Independence, but in time many Presbyterians came to support the Revolutionary War. After the Battles of Lexington and Concord, the Synod of New York and Philadelphia published a letter in May 1775 urging Presbyterians to support the Second Continental Congress while remaining loyal to George III. In one sermon, John Witherspoon, president of Princeton, preached "that the cause in which America is now in arms, is the cause of justice, of liberty, and of human nature". Witherspoon and 11 other Presbyterians were signatories to the Declaration of Independence. Even before the war, many Presbyterian felt that the single synod system was
