This groundbreaking study traces the transformative power of Renaissance humanism in reshaping religious thought and practice across Europe. Centered on the principle of ad fontes—a passionate return to the original sources—humanists revived the languages, texts, and moral philosophies of classical antiquity, sparking a profound renewal in biblical scholarship, theological inquiry, and devotional life. Through meticulous recovery of Greek and Latin manuscripts, the study of the Church Fathers, and innovative educational reforms, humanism challenged medieval scholasticism, inspired ecclesiastical reform, and paved the way for the Reformation and Counter-Reformation.

Benjamin Shaw offers a rich, nuanced exploration of key figures such as Erasmus, Luther, and Catholic humanists, revealing how their engagement with classical learning redefined Christianity's intellectual foundations. This book illuminates the enduring legacy of Renaissance humanism, whose call to critically engage sacred and classical texts continues to shape modern religious scholarship and spiritual practice.

For scholars, students, and readers fascinated by the intersection of culture, faith, and history, this work offers a compelling narrative of how the revival of classical learning catalyzed one of the most dynamic periods of religious transformation in Western civilization.
