I'm not the target audience (agnostic) for this book, so I predictably hated it. Why then am I reading it? The main reason is because my wife attends a Presbyterian church and the preacher gave me this book to read because she told him I wasn't sure about most of these issues.
I didn't like the 200 pages or so I read of it because it's an intolerant little book. The author goes so far as to say that the point of the book is the "proper indoctrination" of believers in the preface. He uses Biblical scripture alone as a reference/support system for making hugely generalized claims in regards to Christianity in general -- just to name a few, a lot of people would disagree with him about the idea of predestination, the Bible as a sacrosanct, divine text, and the idea that we simply have no way out of the idea of original sin.
None of this is set in stone. The Reformed Church's take on it is simply one of many that have existed throughout history. Even when I attended an Anglican church with my parents, I would have struggled to wrap my head around the ideas in this book from time to time.
I really have to wonder if the author ever thought about the kind of philosophical system that he was propounding to his students. Unconditional obedience to God despite his many contradictions and complexities. The convoluted mental gymnastics needed to justify sin in the world if God had the ability to make a world without any sin. The inability to question and the need to worship out of fear of going to hell and punishment. It reminded me a lot of watching a Bergman film -- that very dour, stark world of Protestant guilt and hell that swallows people alive without any sort of happiness or light.
In other words, it's a rather stark worldview and one that I'm not in any way prepared to endorse. There are far better, more modern books to read about Christianity, as well, if you want to learn more about it.
The strange thing is, I think I would have given this book 3 stars if he had simply title the book a bit differently -- if, for example, it had been called "Our Version of Reformed Christianity and Why We Think the Way We Do." That would have been fine and much less frustrating for this reader anyway. It's the author's attitude and his claims about it being for Christianity in general that got me so upset.
