"This much-needed volume opens up the history of eighteenth-century Calvinistic Methodism as a single narrative embracing both England and Wales. It offers superb treatment of the larger-than-life individuals who made this Calvinistic movement nearly the equal of its Wesleyan counterpart - including Griffith Jones, Daniel Rowland, and Howel Harris (Wales), the Countess of Huntington and Thomas Haweis (England), and George Whitefield (everywhere). The book also succeeds in explaining why Calvinistic Methodism faded in England while becoming a permanent part of the Welsh religious landscape. This is an important history very well told." Mark A. Noll, Francis A. McAnaney Professor of History at the University of Notre Dame, is the author of "The Rise of Evangelicalism: The Age of Edwards, Whitefield and the Wesleys"
