Highlighting the demographic, social, and political character of the Evangelical movement in the 1980s and 1990s, Bowen pays particular attention to conversion processes, commitment mechanisms, schisms, and distinctive beliefs. He also considers the controversial issues of religious persecution and American missionary influence. Bowen reveals that Evangelicalism's appeal is so pervasive in Mexico that if Evangelical converts all remained faithful it could become Mexico's dominant religion by 2006. This projection, however, is improbable due to high drop-out rates. Bowen argues that Evangelical apostasy is rooted in the most basic beliefs and practices of its followers.
