Abstract
John Wesley (1703 -1791) was a pioneer of the 1730s British evangelical movement. While best known as founder of Methodism, his intellectual interests included a lifelong engagement with the ideas and activities of the natural philosophers (scientists) of his day. He encouraged his preachers to become conversant with science, incorporated scientific topics in his sermons and other writings, and used electro therapy apparatus in his medical clinics. Science correctly understood was to serve the cause of Christ rather than be feared.
