The ability of Evangelicals to tap popular trends has always been ambiguous. At once it makes faith available to many, and yet it always threatens to careen of track, to make faith less transcendent and more cultural. The movement needs its prophets.
Sharon Hodde Miller has been thinking about this in particular, and tapping into Walter Breuggeman, as in this quote
“I believe the crisis in the U.S. church has almost nothing to do with being liberal or conservative; it has everything to do with giving up on the faith and discipline of our Christian baptism and settling for a common, generic, U.S. identity that is part patriotism, part consumerism, part violence, and part affluence” (A Way Other Than Our Own, p. 3)
