As college students develop their identities and construct their worldviews, they commonly wrestle with fundamental questions such as "Why be moral?" Taking into account feedback he has received from students and colleagues, William Mattison has crafted Introducing Moral Theology, a masterful basic text on Catholic moral theology. This work provides a solid overview of classical virtue ethics (i.e., temperance, prudence, fortitude, and justice) as well as the theological virtues (i.e., faith, hope, and love). Professors and students alike will appreciate the study questions, terms and definitions, bibliographies, and case studies on timely, thorny issues such as premarital sex and euthanasia. Readers will also note that Introducing Moral Theology draws deeply on Thomas Aquinas’s Summa Theologiae. While written primarily to and from a Roman Catholic perspective, this text will appeal to a wide swathe of Christian academics and believers interested in theology and ethics.
