High Churchmen were also enthusiastic organizers of voluntary religious societies. Two of the most prominent were the Society for Promoting Christian Knowledge (founded in London in 1698), which distributed Bibles and other literature and built schools, and the Society for the Propagation of the Gospel in Foreign Parts, which was founded in England in 1701 to facilitate missionary work in British colonies (especially among colonists in North America). Samuel and Susanna Wesley, the parents of John and Charles Wesley (born 1703 and 1707 respectively), were both devoted advocates of High-Church ideas. In the 1730s, Evangelicalism emerged as a distinct phenomenon out of religious revivals that began in Britain and New England. While religious revivals had occurred within Protestant churches in the past, the evangelical revivals that marked the 18th century were more intense and radical. Evangelical revivalism imbued ordinary men and women with a confidence and enthusiasm for sharing the gospel and converting others outside of the control of established churches, a key discontinuity with the Protestantism of the previous era. It was developments in the doctrine of assurance that differentiated Evangelicalism from what went before. Bebbington says, "The dynamism of the Evangelical movement was possible only because its adherents were assured in their faith." He goes on:  The first local revival occurred in Northampton, Massachusetts, under the leadership of Congregationalist minister Jonathan Edwards. In the fall of 1734, Edwards preached a sermon series on "Justification By Faith Alone", and the community's response was extraordinary. Signs of religious commitment among the laity increased, especially among the town's young people. The revival ultimately spread to 25 communities in western Massachusetts and central Connecticut until it began to wane by the spring of 1735. Edwards was heavily influenced by Pietism, so much so that one historian has stressed his "American Pietism". One practice clearly copied from European Pietists was the use of small groups divided by age and gender, which met in private homes to conserve and promote the fruits of revival. At the same time, students at Yale University (at that time Yale College) in New Haven, Connecticut, were also experiencing revival. Among them was Aaron Burr, Sr., who would become a prominent Presbyterian minister and future president of Princeton University. In New Jersey, Gilbert Tennent, another Presbyterian minister, was preaching the evangelical message and urging the Presbyterian Church to stress the necessity of converted ministers. The spring of 1735 also marked important events in England and Wales. Howell Harris, a Welsh schoolteacher, had a conversion experience on May 25 during a communion service.
