The Limits of a Catholic Spirit presents an extraordinary, in-depth study of John Wesley's relationship with Catholicism, examining the limits to which Wesley, as an evangelical Protestant, practiced his ideal of a Catholic spirit. Through the use of rare primary sources from the National Archives, Kelly Diehl Yates provides a refreshing investigation of Wesley's interaction and strained relationship with Catholicism, taking the path less trodden in studies of his theology. While revisionist scholars argue that Wesley proposed principles of religious tolerance in his sermon, Catholic Spirit, Yates argues that he did not expect unity between Protestants and Catholics, remaining wedded to anti-Catholic beliefs himself. By paying attention to this previously unfilled gap in Wesley studies, Yates' exemplary historical and critical study tackles questions which have beset Wesley scholars for decades, including Wesley's relationship with the Jesuits, Jacobitism, the anti-Catholic Gordon Riots of 1780, and his time in Ireland. Grounded in historical case studies, Yates explores these questions from a fresh perspective, providing answers to these questions, and more.
