Which work is associated with Thomas Aquinas as a synthesis of faith and reason?

• A. Proslogion
• B. Summa Theologiae
• C. Confessions
• D. The City of God

Answer: (B)

The idea being tested is how medieval thinkers connected faith with reason. Thomas Aquinas is best known for showing that faith and reason can inform and support one another rather than contradict. The work that embodies this synthesis is the Summa Theologiae. It is a comprehensive, systematically organized guide to Christian theology that uses careful argument and philosophical methods—from Aristotle and natural philosophy—alongside revealed doctrine. Aquinas frames questions, presents objections, and then offers thorough answers, demonstrating how rational inquiry can illuminate truths of faith and how faith can direct and elevate reason. The other works listed come from different authors: the Proslogion is Anselm’s work focused on proving God’s existence via the ontological argument; the Confessions and The City of God are Augustine’s, exploring personal faith and Christian philosophy, not Aquinas’s synthesis.
