The Protestant Reformation placed intense scrutiny on religious belief in early modern England. But how did this belief work? What resources did it draw on? How did such a faith differ from other kinds of assent? In this interdisciplinary study, Joseph Ashmore argues that early modern literature became a key site for handling these questions. Focusing on late sixteenth- to mid seventeenth-century writing, he shows how Protestant authors turned to contemporary legal discourses to represent and analyse faith. Techniques for evaluating courtroom testimony became a powerful tool for investigating what was distinctive about religious belief. Examining the sermons of Lancelot Andrewes and John Donne, the philosophy and prose fiction of Francis Bacon, and the poems of Henry Vaughan, Ashmore shows how legal notions of evidence shaped discussions of faith across a number of different genres, and within a variety of social and political contexts.
