Anthony Sacramone has it exactly right in an entry in the First Things weblog:
Because we are faced with the fact of ecclesiological chaos does not make it healthy or desirable. I would argue that it may even be spiritually corrupting. Look, I’ve been there myself. As I wrote a while back in this space, I spent a good, long time—years—collecting church bulletins like frequent fliers collect air miles. But I never considered potluck Protestantism a great good. I was church shopping because I was looking for The Church and kept getting bounced back like an email with an old Prodigy.com domain name. I found the multiformity baffling, the sheer subjectivity and inconstancy depressing.
I confess that I, too, find church shopping – what a horrible phrase – oppressive and depressing.
