John Wesley (/ˈwɛsli, ˈwɛzli/; 28 June [O.S. 17 June] 1703 – 2 March 1791) was an Anglican cleric and Christian theologian who, with his brother Charles Wesley and fellow cleric George Whitefield, is credited with the foundation of the evangelical movement known as Methodism. His work and writings also played a leading role in the development of the Holiness movement and Pentecostalism.A key step in the development of Wesley's ministry was, like Whitefield, to travel and preach outdoors. In contrast to Whitefield's Calvinism, however, Wesley embraced the Arminian doctrines that dominated the Church of England at the time. Moving across Great Britain, North America and Ireland, he helped to form and organise small Christian groups that developed intensive and personal accountability, discipleship and religious instruction. Most importantly, he appointed itinerant, unordained evangelists to travel and preach as he did and to care for these groups of people. Under Wesley's direction, Methodists became leaders in many social issues of the day, including prison reform and abolitionism.Although he was not a systematic theologian, Wesley argued for the notion of Christian perfection and against Calvinism – and, in particular, against its doctrine of predestination. He held that, in this life, Christians could achieve a state where the love of God "reigned supreme in their hearts", giving them outward holiness. His evangelicalism, firmly grounded in sacramental theology, maintained that means of grace were the manner by which God sanctifies and transforms the believer, encouraging people to experience Jesus Christ personally.Throughout his life, Wesley remained within the established Anglican church, insisting that the Methodist movement lay well within its tradition. Although sometimes maverick in his interpretation and use of church policy, he became widely respected and, by the end of his life, had been described as "the best loved man in England".
Charles Wesley (/ˈwɛsli, ˈwɛzli/; 18 December 1707 – 29 March 1788) was an English leader of the Methodist movement, son of Anglican clergyman and poet Samuel Wesley, the younger brother of Methodist founder John Wesley and Anglican clergyman Samuel Wesley the Younger. He was father of musician Samuel Wesley and grandfather of musician Samuel Sebastian Wesley. Despite their closeness, Charles and his brother John did not always agree on questions relating to their beliefs. In particular, Charles was strongly opposed to the idea of a breach with the Church of England into which they had both been ordained. Charles Wesley is mostly remembered for the over 6,000 hymns he wrote. He ministered for part of his life in The New Room Chapel in Bristol. His house, located nearby, can still be visited.
