Someone was helpfully passing this article around on social media today.
I read it as a lament from someone critiquing the current Evangelical culture that is (once again) trying to remake itself.
A church trend I’d be more than happy to add in as likewise immature is the tendency to be so self-congratulatory about how socially aware we are, and the perverse delight in seeing how “transgressive” we can be. (This last particularly after almost straining my face muscles from an extended session of eye-rolling after discovering the bookstore of a certain major church in a certain northeastern city stuffed to the gills with Elaine Pagels’ books as she was coming to speak there…)
I wouldn’t say that these are so much “childish” as quite “adolescent.”
