know where they are, where they are going, and how to get there. Moral theology examines the same three truths. The Christian Moral Life is a handbook for moral theology that uses the theme of a journey to explain its key ethical concepts. First, humans begin with their creation in the image of God. Secondly, the goal of the journey is explained as a loving union with God, to achieve a share in his eternal happiness. Third and finally, the majority of the book examines how to attain this goal. Within the journey motif, the book covers the moral principles essential for attaining true happiness. Based on an examination of the moral methodology in the bible, the book discusses the importance of participating in divine nature through grace in order to attain eternal happiness. It further notes the role of law, virtue, and the gifts of the Holy Spirit in guiding and transforming humans into friends of God, who participate in his happiness. Following this section on moral theology in general, the book analyzes the individual virtues to give more concrete guidance. The entire project builds upon the insights of great Christian thinkers, such as Thomas Aquinas, Thérèse of Lisieux, and John Paul II, to uncover the moral wisdom in scripture and to show people how to be truly happy both in this life and the next. This book will be of great interest to undergraduate students of moral theology, priests and seminarians, parents and teachers seeking to raise and to form happy children, and anyone interested in discovering the meaning of true happiness.
