A revisionist study of the political and ecclesiological theories of the fourteenth-century philosopher John Wyclif.John Wyclif was the fourteenth-century English thinker responsible for the first English Bible, and for the Lollard movement - persecuted widely for its attempts to reform the church through empowerment of the laity. Several of Wyclif's formal, Latin works proposed that the king ought to take control of all church property and power in the kingdom, a vision close to what Henry VIII was to realise 150 years later. This book argues that Wyclif's political programme was based on a coherent philosophical vision ultimately consistent with his earlier reformative ideas.John Wyclif was the fourteenth-century English thinker responsible for the first English Bible, and for the Lollard movement - persecuted widely for its attempts to reform the church through empowerment of the laity.
