Jan, it should be remembered that a whole host of internet debate took place several weeks BEFORE the book by Rob Bell was actually published - and was based on the editor's comments on the back of the cover, which Collins released to Amazon because of the high level of pre-orders they were receiving. Don't know of anyone who has read the book in its entirety, nor do I know when Pastor Holtz made his Facebook post, but it does seem to have been "in defence of a forthcoming book", so it seems unlikely that he had read the book either.  The only person I know to have read any of it says that the first 3 1/2 chapters (ie as far as he had read at that point) have absolutely nothing controversial or unorthodox in them.
