For the past 20-plus years, the overwhelming majority of my students have come from schools that could, to one degree or another, accurately be described as part of "evangelical" Protestant life here in America.

Yes, there are quotes around the word "evangelical," not because the word is scary, but because many people, including journalists, are not sure what it means.

Early on, most of my students -- when asked what kind of church they attend -- would have described themselves as part of flocks that were "independent," "nondenominational" and "evangelical." A few would have added the word "charismatic." The common denominator, however, was the word "evangelical."

Then, about six or seven years ago, that totally changed. Oh, most of my students still come from schools that can be called "evangelical." Most grew up in "evangelical" churches and most still attend churches that can be called "evangelical" to one degree or another. However, many if not most students are now backing away from that word -- "evangelical."

The reason why is pretty obvious: "Evangelical" has become a political term in public discourse.
