From an obscure Jewish sect to a dominant world religion, Christianity's transformation represents one of history's most consequential religious developments. But how did a movement that began with a Jewish teacher in Galilee evolve into a predominantly Gentile faith that would reshape Western civilization? This groundbreaking book reveals the complex and fascinating story of how early Christianity reinterpreted its Jewish origins as it forged a distinctive religious identity.

Drawing on the latest archaeological discoveries, forgotten manuscripts, and cutting-edge historical methods, this compelling narrative challenges the traditional view that Judaism and Christianity made a clean and immediate break. Instead, readers will discover a messier, more human story of gradual differentiation occurring at different rates across the Mediterranean world-a process shaped as much by political circumstances and social pressures as by theological debates.

The book takes readers on a journey from Jerusalem's Temple Mount to Rome's catacombs, from Alexandria's philosophical schools to Constantinople's imperial court. Along the way, readers will encounter Jewish-Christians who maintained Jewish practices while believing in Jesus, church fathers who consulted rabbis for biblical interpretations while claiming interpretive superiority, and ordinary believers navigating complex religious identities in an increasingly Christian empire.

This fresh examination of Christianity's Jewish roots illuminates pivotal questions that continue to shape interfaith relations today: How do related religious traditions distinguish themselves while acknowledging shared heritage? What happens when theological claims align with political power? How do sacred texts foster both connection and competition between communities? By exploring these questions through rich historical detail and compelling storytelling, this book offers valuable perspective on religious identity formation that remains relevant in our diverse contemporary world.

Perfect for readers interested in religious history, Jewish-Christian relations, and the origins of Western civilization, this accessible yet scholarly work challenges simplistic narratives of religious separation while revealing the complex human story behind ideas and institutions that continue to shape our world today.
