The Disruption of Evangelicalism: The Age of Torrey, Mott, McPherson and Hammond - is the fourth volume in the A History of Evangelicalism series.

This volume provides the first comprehensive account of the evangelical tradition in the English-speaking world from the end of the nineteenth to the mid twentieth century. It offers fresh perspectives on conversionism, the life of faith, reflections on the Bible and theology, and social engagement. These trajectories, through a period of great turbulence in world history, furnished the setting for the deepening diversification of the movement. This led to the fragmentation of the once broad evangelical spectrum into various (and often competing) strands.

Division of the era into two phases - before 1914 and after 1918 - draws out the impact of the Great War of 1914 - 1918, as evangelical identity in the modern world was renegotiated. The book argues that the early twentieth century was primarily an age of disruption. The careers of Rubin Archer Torrey, John Mott, Aimee Semple McPherson and T.C. Hammond illustrate the very different responses of evangelicals to the demands of this time of transition.
