Evangelicalism (/ˌiːvænˈdʒɛlɪkəlˌɪzəm/, /ˌɛvən/-), Evangelical Christianity, or Evangelical Protestantism is a worldwide, transdenominational movement within Protestant Christianity which maintains the belief that the essence of the gospel consists of the doctrine of salvation by grace through faith in Jesus Christ's atonement. Evangelicals believe in the centrality of the conversion or the "born again" experience in receiving salvation, in the authority of the Bible as God's revelation to humanity, and in spreading the Christian message.
Its origins are usually traced back to English Methodism, the Moravian Church (in particular theology of its bishop Nicolaus Zinzendorf and his community at Herrnhut), and German Lutheran Pietism. While all these phenomenons contributed greatly, John Wesley and other early Methodists were at the root of sparking this new movement during the First Great Awakening. Today, Evangelicals are found across many Protestant branches, as well as in various denominations not subsumed to a specific branch. Among leaders and major figures of the Evangelical Protestant movement were John Wesley, George Whitefield, Jonathan Edwards, Billy Graham, Harold John Ockenga, John Stott and Martyn Lloyd-Jones. The movement gained great momentum during the 18th and 19th centuries with the Great Awakenings in the United Kingdom and North America.
