Sociologist Alan Wolfe, Director of the Boisi Center at Boston University, spent several years studying the beliefs and practices of evangelical churches. Specifically, he studied whether evangelicals actually practice what they profess to believe.

“In every aspect of the religious life, American faith has met American culture–and American culture has triumphed. Whether or not the faithful ever were a people apart, they are so no longer; . . . Talk of hell, damnation, and even sin has been replaced by a nonjudgmental language of understanding and empathy. . . . far from living in a world elsewhere, the faithful in the United States are remarkably like everyone else.” p. 3

“[W]atching sermons reduced to PowerPoint presentations or listening to one easily forgettable praise song after another makes one long for an evangelical willing to stand up, Luther-like, and proclaim his opposition to the latest survey of evangelical taste.” p. 256
