Saint Thomas Aquinas has been admired throughout the ages for his philosophical brilliance and his theological sanity, but author and professor Peter Kreeft thinks the practical spiritual wisdom of Aquinas is just as amazing. In this book, Kreeft brings together 358 useful, everyday insights from Aquinas' masterpiece the Summa Theologiae. He pairs these easily digestible quotes from the Summa with his own delightfully written commentary in order to answer the kinds of questions real people ask their spiritual directors. These 358 passages from the Summa have helped Kreeft in his own struggles to grow closer to the Lord. His practical, personal, and livable advice is the fruit of his labors to apply the insights of Aquinas to his own quest for sanctity, happiness, and union with God.
