Methodism, also known as the Methodist movement, is a group of historically related denominations of Protestant Christianity which derive their practice and belief from the life and teachings of John Wesley. George Whitefield and John's brother Charles Wesley were also significant early leaders in the movement. It originated as a revival movement within the 18th-century Church of England and became a separate denomination after Wesley's death. The movement spread throughout the British Empire, the United States, and beyond because of vigorous missionary work, today claiming approximately 80 million adherents worldwide.
Wesleyan theology, which is upheld by the Methodist Churches, focuses on sanctification and the effect of faith on the character of a Christian. Distinguishing Methodist doctrines include the new birth, assurance, imparted righteousness, the possibility of entire sanctification, the works of piety, and the primacy of Scripture. Most Methodists teach that Jesus Christ, the Son of God, died for all of humanity and that salvation is available for all; in theology, this view is known as Arminianism. This teaching rejects the Calvinist position that God has pre-ordained the salvation of a select group of people. However, Whitefield and several other early leaders of the movement were considered Calvinistic Methodists and held to the Calvinist position. In addition to evangelism, Methodism emphasises charity and support for the sick, the poor, and the afflicted through the works of mercy. These ideals, collectively known as the Social Gospel, are put into practice by the establishment of hospitals, orphanages, soup kitchens, and schools to follow Christ's command to spread the good news and serve all people.
The movement has a wide variety of forms of worship, ranging from high church to low church in liturgical usage. Denominations that descend from the British Methodist tradition are generally less ritualistic, while American Methodism is more so, the United Methodist Church in particular. Methodism is known for its rich musical tradition, and Charles Wesley was instrumental in writing much of the hymnody of the Methodist Church.
