Did Christianity as it's practiced today come from Jesus or from a man who never met him? This book traces how Paul of Tarsus, a former persecutor of Jesus's followers who based his authority on a private, unwitnessed vision, introduced theology that diverged sharply from Jesus's own recorded teaching: salvation by faith rather than the Law, a Gentile-focused mission rather than one to "the lost sheep of Israel," and a Christology later ratified politically at the Council of Nicaea under Emperor Constantine. Framed honestly as one contested interpretive tradition rather than settled consensus, it asks a question many believers are never encouraged to ask: how much of mainstream Christianity reflects the religion of Jesus, and how much reflects a religion built about him.
