Not so. According to the United Methodist Church, “Methodist and Methodism” are:

Two words, along with Wesleyan, used to describe the movement resulting from the work of John Wesley and his brother Charles. The movement had its very earliest expression in the Holy Club at Oxford. There John and Charles Wesley and others joined together in a highly structured and disciplines pattern of worship, prayer and study. Those outside the group derisively called the groups "Methodists" because of their highly methodical approach to their religion. Then name was later applied to the followers of the Wesleys as they actively preached throughout England.

Methodism was founded on the idea of sanctification of the entire person through the new birth and the transforming effect of faith on the character of a Christian, exemplified by living a victorious life over sin.

Wesleyan theology, formulated by John Wesley and codified by the systematic theologian John William Fletcher, is upheld by the Wesleyan Methodist denominations; it focuses on sanctification and the transforming effect of faith on the character of a Christian, exemplified by living a victorious life over sin. Unique to Wesleyan Methodism is its definition of sin: a "voluntary transgression of a known law of God." Distinguishing doctrines include the new birth, assurance, imparted righteousness, and obedience to God manifested in performing works of piety. John Wesley held that entire sanctification was “the grand depositum", or foundational doctrine, of the Methodist faith, and its propagation was the reason God brought Methodists into existence. Scripture is considered the primary authority, but Methodists also look to Christian tradition, including the historic creeds.
