I purchased this book on the recommendation of Dr. Robert M. Price on his "Bible Geek" podcast.
The book was a disappointment. It covers a lot of ground, in a lot of chapters, but the discussion of any one subject is very brief and occasionally superficial. There are far better books available covering all the aspects of theism in general and Christianity in particular covered here.
The author's purpose is to recommend Christian Nontheism, a philosophy that retains what he admires about Christianity but jettisoning the supernatural or mythological aspects. I remain unconvinced that this is a practical proposition. The phrase Christian Nontheism seems to be an oxymoron. Christianity is all about theism. The author points out that there are over 20,000 denominations that call themselves Christian so that precisely what constitutes Christianity has always been somewhat fuzzy so perhaps an entirely nontheist view can slip into the tent. Again, I remain skeptical. At some point words have to retain some meaning and Bennett is stretching the meaning of "Christian" beyond the breaking point.
The author writes well and has a friendly style with plenty of personal anecdotes and touches of humor. This makes for a quick and easy read. He sincerely feels he has something of value to share. I am sympathetic but can't help but feel that he just can't bring himself to take that final step of abandoning Christianity altogether.
