Servais Pinckaers, O.P., is one of the preeminent Catholic moral theologians of his generation. His highly acclaimed works, among them The Sources of Christian Ethics, offer a thoroughly Thomistic and contemporary vision of the Christian moral life. They reflect the philosophical and spiritual prowess of a moral theologian who is estranged neither from philosophical ethics nor from dogmatic theology, neither from Scripture nor from spirituality. The first collection of its kind available in any language, this volume features the twenty most significant essays written by Pinckaers since his highly praised Sources. The essays offer profound reflections that are only possible by a contemporary moral theologian who knows the thought of Aquinas from lifelong study. Rather than taking a simply historical approach to Aquinas, Pinckaers seeks the basis of the intelligibility of the moral life, providing rich spiritual and theological insights along the way. He plumbs the depths of fundamental moral theology in these essays, where he treats Thomistic method and the renewal of moral theology, beatitude and Christian anthropology, moral agency, and passions and virtues, as well as law and grace. Such a detailed treatment of key issues in fundamental moral theology and Christian philosophical anthropology will certainly demand attention from every theologian and advanced student interested in Aquinas and in a virtue approach to Christian ethics. Pinckaers's work has been an important source for the revival of interest in virtue-oriented moral theology in recent years and will continue to be a major source for debates over the place of Scripture and the Holy Spirit in moral theology.
