Nathan Johnstone looks at the ways in which beliefs about the nature of the Devil and his power in human affairs changed as a consequence of the impact of the Reformation. Departing from the established focus on demonology as a component of witchcraft, he examines a wide range of religious and political milieux, such as practical divinity, Puritan godliness, anti-popery, polemic and propaganda, and popular culture. The concept of the Devil that emerges not only had a profound impact on the beliefs and practices of committed Protestants, but influenced the political debates of the reigns of Elizabeth I, James I and Charles I, as well as popular culture, "engaging book" - Jonathan Wright, Independent Scholar, Hartlepool, UK "Johnstone's ambitious book gets to the core of early modern English culture by giving serious attention to a society's gravest fears." Gregory Dodds, Renaissance Quarterly "Johnstone has presented a lively and thoughtful piece of scholarship and has offered some stimulating perspectives from which to view the troubled minds and hearts of early modern English." -David Parnham, Victoria, Australia, Church History "...Johnstone presents a valuable picture of the integral role of the devil and suggests new ways of analyzing demonism in the English Protestant experience." -Amy Rebok Rosenthal, The Historian An original and powerful examination of the concept of the Devil in early modern England.
