Vavasor Powell was born in Cnwc-glas, Radnorshire and died in Fleet prison on 19 September 1691. He was educated at Jesus College, Oxford and converted on reading Richard Sibbes's The Bruised Reede and hearing Cradock preach. Powell took part in the civil war, led the opposition to Goodwin, the most formidable exponent of universal redemption, and dedicated himself to Wales as an itinerant preacher under the 1650 Act for the better propagation of the Gospel in Wales. He was more orthodox than some of the more radical Puritans in Wales, despite his adhesion to the cause of the Fifth Monarchy Men. He organized opposition to Cromwell in Wales in his manifesto A Word for God (1655), and was arrested following the Restoration, spending most of the time between 1660 and 1670 in prison.
