Moral Re-Armament's followers hailed it as the most important spiritual movement of the twentieth century. It claimed supporters from Mohandas Gandhi to Mae West, who praised its contributions to global understanding and personal happiness. Critics saw MRA as naïve and possibly dangerous, cozy with fascism or a front for corporate power. Fundamentalists called it a cult. With its mixture of American evangelicalism, popular psychology, and show business, it attracted men and women on six continents. This book traces Moral Re-Armament's reinventions over fifty years, from its Ivy League beginnings to its spiritual heirs, Up With People and Alcoholics Anonymous.
