In this study of Madame Guyon and, her defender, Francois de Fénelon, the Archbishop of Cambray, Patricia Ward demonstrates how the ideas of these seventeenth-century Catholics were transmitted into an ongoing tradition of Protestant devotional literature—one that continues to influence American evangelicals and charismatic Christians today. Down a winding (and fascinating) historical path, Ward traces how the lives and writings of these two somewhat obscure Catholic believers in Quietism came to such prominence in American spirituality—offering, in part, a fascinating glance at the role of women in the history of devotional writing.
