The Summa Theologica (Thomas Aquinas)

The *Summa Theologica* is a comprehensive work by Saint Thomas Aquinas that outlines Christian theology and philosophy. Written in the 13th century, it systematically addresses key questions about God, ethics, human existence, and salvation. Aquinas employs a question-and-answer format, exploring arguments for and against various topics, ultimately aiming to reconcile faith with reason. His work is foundational in Catholic theology and has influenced Western thought, providing a methodical approach to understanding complex spiritual and ethical matters. It serves as a bridge between ancient philosophy and medieval Christian belief.
