Charles Wesley was born in 1707 in Epworth, Lincolnshire, the eighteenth child of Samuel and Susanna Wesley. Educated at Christ Church, Oxford, he helped found the small disciplined circle of students that critics mockingly called the "Methodists" — a name that would outlast the mockery. He was ordained as an Anglican priest and, like his brother John, underwent a decisive evangelical conversion in May 1738, just days before John's more celebrated Aldersgate experience. He spent much of the rest of his life as a traveling preacher before settling in Bristol and later London, where he died in 1788.

Wesley lived through a period of considerable religious complacency within the established Church of England, alongside widespread poverty and social dislocation brought on by early industrialization. The Methodist movement arose partly in response to these conditions, carrying Christian proclamation to miners, laborers, and the poor through open-air preaching and tightly organized societies. Charles shared his brother's urgency but was more cautious about breaking with Anglican structures, a tension that shaped his later years.

His enduring contribution was not administrative but lyrical. He composed somewhere in the range of six thousand hymns — figures vary, but the output was extraordinary by any measure — including "Hark! The Herald Angels Sing," "O for a Thousand Tongues to Sing," and "Love Divine, All Loves Excelling." These were not mere versifications of doctrine but genuine theological poetry, drawing on scripture, patristic sources, and the cadences of classical literature to render grace, redemption, and sanctification accessible and emotionally immediate. His hymns functioned as a kind of portable catechesis, shaping the faith of generations who sang their way into understanding.

His legacy persists wherever congregations still lift those hymns in worship, finding in language written nearly three centuries ago a theology that continues to bear the weight of devotion.
