I am reading David Bentley Hart's latest offering, The Experience of God: Being, Consciousness, Bliss (Yale, 2013). I came across it in a review in The Guardian newspaper written by someone sympathetic to atheism. This guy was raving about the book and described it as the one book every atheist should read. I am well into it now and I can see why he thought it was so good.
In essence all that the book seeks to do is to offer some generic clarification for the word "God." This is not a work in specifically Christian theology but it draws deeply on the classical Christian tradition.
The reason for the need for clarification is that much of the contemporary "God debate" begins with an assumption that we all know what we mean by "God" and so we can get on with the business of showing whether God does or does not exist. However, it is pretty clear from the arguments of the New Atheists that what they are arguing against is not God but a god; not Being Itself but a being, albeit a supreme being. And it is not simply them. The Intelligent Design movement also operates with a reduced notion of the divine as one causal agent operating in the world alongside others, i.e., a god, not God.
Not only does Hart beautifully spell out the classical notion of God but in so doing dissolves most of the so-called arguments against God and exposes the incoherence of naturalism.
