This Book Takes One Step Further The Long-Standing Debate Among Scholars Of Religious Antiquity Over When And Why A Parting Of The Ways Happened Between Judaism And Christianity In The Early Centuries Of The Common Era. It Explores Three Interrelated Questions: What Might Have Happened To Prevent That Split; How Might Western Religion Have Looked Had The Split Not Occurred; And How Might Features Of That Religion Which Never Existed Nonetheless Manifest In Some Of The Literature And Artworks Of The Past Half Millennium. The Book Envisions A Religion That Stands Between Historical Judaism And Christianity—A Counterfactual Construction That Challenges Jews And Christians To Rethink Their Actual Identities Today.
