The title of this book may seem startling. But if you are no longer sure about Christian beliefs such as a literal incarnation or resurrection, yet still find church services aesthetically uplifting and being part of a community important, you may find this book a great help and comfort. Similarly, if you want to understand how it is possible to be pro-Christianity while not holding any supernatural beliefs, the interviews with various types of "Christian Atheist" will give you an insight into their thought processes. Mountford argues that there is much to be gained for the Church by embracing those in the grey area between ingroup and outgroup, that actually most of us can be found there, and that there are many shared values. These are not your hard line, reductionist atheists, but ones who have a "religious temperament": an interest in questions about the nature of reality, and a taste for what might be called transcendent (but not necessarily supernatural) experiences.
There are useful discussions about the relationship between faith and action, about the role of personality in faith, about the parallels between art and theology. I particularly liked a description of what is distinctive about Christian morals, and the conclusion that while Christianity may not provide a unique basis for ethics, I can still be proud of the traditions of Christ, such as loving your enemy, valuing the dignity of all human life, selling all you have and giving to the poor, the first being last, and so on.
Having read the book, I feel happier that the ongoing journey is about questions more than answers, about suffering more than solutions, and about change rather than preserving the status quo. And knowing that an Anglican priest, as well as fellow churchgoers, are happy with a metaphorical interpretation of the Bible and doctrine is very helpful.
