One in three Americans under the age of 30 reports being religiously unaffiliated, so it may be a surprise to learn that religion is making a comeback on American campuses. It’s not that campuses have become holy places, and religious zealots are not calling the shots. But religion is no longer marginalized from campus life as it was in the late 20th century. A generation ago, many Americans and most colleges and universities could live with the myth that religion was a purely private matter, but today no one questions that religion can have powerful effects on individuals and societies.
