I can't compare this to other works on the history of Christianity because I've never read any... which demonstrates, perhaps, that this book is attractive and accessible to people who don't normally pick up that sort of thing.
I found it a useful and entertaining overview. It put my vague and half-understood notions about the history of the faith into context and I now feel as though I have some sort of framework in which to find out more.
It was also, in places, extremely funny. Money well spent.
