Charles Wesley was the eighteenth child of Susanna Wesley and Samuel Wesley. He was born in Epworth, Lincolnshire, England, where his father was rector. He was educated at Westminster School and Christ Church, Oxford, where he was ordained. At Oxford, Charles formed a prayer group among his fellow students in 1727; his elder brother, John, joined in 1729, soon becoming its leader and moulding it in line with his own convictions. They focused on studying the Bible and living a holy life. Other students mocked them, saying they were the "Holy Club", "Sacramentarians", and "the Methodists", being methodical and exceptionally detailed in their Bible study, opinions and disciplined lifestyle. George Whitefield joined the group. After graduating with a master's degree in classical languages and literature, Charles followed his father and brother into Anglican orders in 1735.
