Methodism, or the Methodist movement, is a group of historically related denominations of Protestant Christianity which derive their inspiration from the life and teachings of John Wesley. George Whitefield and John's brother Charles Wesley were also significant leaders in the movement. It originated as a revival within the 18th century Church of England and became a separate Church after Wesley's death. Because of vigorous missionary work, the movement spread throughout the British Empire, the United States and beyond, today claiming approximately 80 million adherents worldwide.
Wesley's theology focused on sanctification and the effect of faith on character. Distinguishing Methodist doctrines include an assurance of salvation, imparted righteousness, the possibility of perfection in love, the works of piety and the primacy of Scripture. Methodism also emphasises charity and support for the sick, the poor and the afflicted through the works of mercy. These ideals are put into practice by the establishment of hospitals, orphanages, soup kitchens and schools to follow Christ's command to spread the Gospel and serve all people. Most Methodists teach that Christ 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 others were considered Calvinistic Methodists and held to the latter position.
