In this book, Debray traces the episodes of the genesis of God, his itinerary and the costs of his survival, going back from the Law to the Tablets themselves and scrutinizing Heaven at its most down-to-earth.

Throughout this beautifully illustrated book, he is able to focus his attention not just on what was written, but on how it was written: with what tools, on what surface, for what social purpose and in what physical environment. God: An Itinerary takes the reader from the invention of a God for nomadic cattle herders to a world dominated by God's own moralizing 'cowboys'. In doing so, it links the history of the Everlasting with the history of the West, illuminating both in the process, and throwing light on contemporary civilisation itself.
