help! book on Christianity

[qatarperegrine]

A few months ago I read an LJ entry that discussed a book on the author's problems with Christianity. My LJ friend listed maybe 10 such problems; the only one I remember stated that progressive Christianity isn't any more useful than traditional Christianity, because it interprets Christianity in the light of an external value system and therefore adds nothing that can't be found outside religion.

If anybody knows what the heck book I'm talking about, please let me know.
