Which medieval theologian is associated with the Summa Theologiae and the synthesis of faith and reason?

• A. Augustine of Hippo
• B. Thomas Aquinas
• C. Peter Lombard
• D. Hildegard of Bingen

Answer: (B)

This question tests recognizing who is famous for the Summa Theologiae and for marrying faith with reason. Thomas Aquinas is the best fit. A Dominican thinker of the 13th century, he produced the Summa Theologiae as a comprehensive guide to Christian doctrine that explicitly shows how reason and revelation illuminate each other. He argues that truth can be reached by reason and by faith, and that philosophy (especially Aristotelian thought) can clarify and support theological teachings. This synthesis—using philosophical argument to explore and explain faith while accepting revealed truth—became a hallmark of scholastic theology.

Augustine of Hippo contributed foundational ideas about faith and reason earlier in the medieval/late antique tradition, but he did not author the Summa. Peter Lombard wrote the Four Books of Sentences, a major medieval compendium used in theological education, not the Summa. Hildegard of Bingen was a mystic and writer, celebrated for visionary and devotional work rather than for organizing a systematic integration of faith and reason like Aquinas.
