Far from being the immutable 'Rock of Ages' He is often assumed to be, the God of Christian history and tradition has had many different and often conflicting faces. Rock of Ages? opens with the emergence of the Biblical God from the pantheon of deities in bronze age Canaan, and culminates in the radical images of God that were appearing at the end of the twentieth-century, providing a historical overview of the different and sometimes conflicting ways in which He has been understood.

By examining the ideas of key writers down the ages, whose ecclesiastical or intellectual power has allowed their insights to become embedded in the mainstream traditions of the Christian churches, Butler seeks to answer one central question: Why is it that people across the ages have claimed to have seen so many different and sometimes contradictory faces of the Christian God? Or more specifically: If there is one true God, and if He is known to those who believe in him through the revelation of Himself in history, why hasn't a consistent and unified understanding of Him emerged in the witness and testimony of those who claim to have seen his face? In the best of scholarly traditions, Butler presents his work as a clear account of his own quest for an answer; but although suggesting possibilities, he leaves others to come to their own judgements using the evidence available. Written in a clear and attractive style, this is a book for anyone without any prior knowledge of history, theology or philosophy, be they atheists, Christians looking to explore their faith, students or simply anyone interested in the history of religion.
