Evangelicalism (/ˌiːvænˈdʒɛlɪkəlɪzəm, ˌɛvæn-, -ən/), evangelical Christianity, or evangelical Protestantism,[a] is a worldwide, trans-denominational 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.[1][2][3] Evangelicals believe in the centrality of the conversion or "born again" experience in receiving salvation, in the authority of the Bible as God's revelation to humanity, and in spreading the Christian message. The movement has had a long presence in the Anglosphere before spreading further afield in the 19th, 20th and early 21st centuries.
Its origins are usually traced to 1738, with various theological streams contributing to its foundation, including English Methodism, the Moravian Church (in particular its bishop Nicolaus Zinzendorf and his community at Herrnhut), and German Lutheran Pietism. Preeminently, 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.[4] Among leaders and major figures of the evangelical Protestant movement were John Wesley, George Whitefield, Jonathan Edwards, Billy Graham, Bill Bright, 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 Great Britain and the United States.
In 2016, there were an estimated 619 million evangelicals in the world, meaning that one in four Christians would be classified as evangelical.[5] The United States has the largest concentration of evangelicals in the world.[6] American evangelicals are a quarter of the nation's population and its single largest religious group.[7][8] The main movements are Baptist churches, Evangelical Anglicanism,[9] Wesleyanism,[10] Confessional Reformed churches, including the Presbyterian Church in America, Pentecostalism, charismatic Evangelicalism, neo-charismatic Evangelicalism and nondenominational Christianity.
