This work investigates the complex evolution of Christian theological and social attitudes toward Jewish populations throughout the medieval period. Michael Frassetto, a scholar specializing in medieval religious history, examines the shifting dynamics between these two groups from the early Church through the late Middle Ages. By analyzing primary ecclesiastical texts, legal decrees, and popular cultural expressions, the author argues that Christian perceptions were not monolithic but fluctuated based on shifting political power, theological disputes, and socioeconomic pressures.

Scholars frequently cite this text as a balanced and accessible overview of a highly contentious historical subject. It is widely regarded as a foundational resource for students and researchers seeking to understand the institutional roots of medieval religious intolerance.
