F.J. Sheed's Theology and Sanity is a classic Catholic book that explains how theology, often considered complex, is actually a practical guide to sanity and meaningful living in the real world, showing how the Catholic faith shapes everyday experiences into experiences that make sense and connect with God, ideal for laypeople who want to understand the relationship between doctrine and real life. In this book, Sheed argues that theology is not just an intellectual study, but the foundation for understanding reality and living a 'sane' life according to divine truth, not just human reason. Bridging the gap between complex Catholic teachings and the daily lives of laypeople, using logic and clear language to make it easy to understand.
