It has been discussed here and elsewhere that generic American Evangelicalism is having a negative, destructive affect on many denominations, turning many churches into generic, cross-less, positive-thinking social clubs. Bunnie Diehl blog writes about the effect that American Evangelicalism is having on denominations that used to keep more to themselves, see Not Liberal, but Generic.
I just started reading D.G. Hart's Deconstructing Evangelicalism. I found it ironically interesting that Hart proposes that:
"Evangelicalism needs to be relinquished as a religious identify because it does not exist. In fact, it is the wax nose of American Protestantism...it is a face void of any discernible features. The nonexistence of an evangelical identity may prove to be, to borrow a phrase from (Mark) Noll, the real scandal of modern evangelicalism."
So then, if D.G. Hart, who is a Presbyterian (I believe) sees the dangers of the American Evangelical movement, then we, as Lutherans, need also to be ready to defend gospel when fellow Lutherans suggest creating "seeker-friendly" worship, less "offensive" communion practices, etc.
I've only read one chapter of this book and can't wait to keep reading.!
