Writing in a conversational style filled with stories and examples, Jim Keenan breaks open the treasure trove of resources in the Catholic tradition for developing moral wisdom. He reclaims four key texts that bishops and lay people alike appealed to in nurturing their moral wisdom–the person of Jesus in the New Testament, the ten commandments in the catechism, the practice of the corporal works of mercy, and the development of the four cardinal virtues–and lifts up the lessons on love, conscience, sin, and suffering within these texts that form the content of the Catholic moral tradition.
