This detailed historical study meticulously compiles the biographies and writings of notable Jewish converts to Christianity from the early Church through the post-Reformation period. The author addresses a profound historical and theological question: why prominent rabbis, scholars, philosophers, and physicians chose to abandon Judaism and embrace the Christian faith. The volume is structured around geographical and ecclesiastical divisions, tracing converts within the Eastern Church, the Roman Catholic Church, and later the various Protestant denominations. Throughout the text, the author examines the genuine convictions, intellectual pursuits, and public works of these historical figures, rather than relying on superficial generalizations.
Readers are introduced to significant personalities such as Pablo Christiani, Paul of Burgos, and numerous others who left behind voluminous theological, grammatical, and polemical works. The narrative explores the complex motivations behind these conversions, the severe persecutions and social pressures often faced by the converts, and their subsequent missionary zeal directed toward their former co-religionists. Special attention is given to institutional efforts to evangelize the Jewish population, including the history of the Domus Conversorum in London. The text balances biographical detail with deep theological inquiry, presenting primary source materials, personal letters, and confessions of faith that reveal intense inner spiritual conflict and resolution. Ultimately, the work serves as a comprehensive historical record of the intersection between Jewish heritage and Christian theology, culminating in a reflection on faith, identity, and spiritual transformation.
