John Wesley Redfield (1810-1863), controversial 'lay' evangelist in the Methodist Episcopal and later Free Methodist churches, was the cofounder of the Free Methodist Church and in the 1840s and 50s had a broad ministry in the M.E. Church and beyond. An outspoken abolitionist, Redfield was controversial among Methodist leaders and in the M.E. press as his revivals typically were marked by dramatic emotional manifestations, including people being slain in the Spirit and dramatic conversions.
