The encyclical Veritatis splendour established certain authoritative directions for doing Christian ethics from a Catholic perspective. The Moral Thought presents the foundations of moral theology and sets out parameters for the discipline that will continue to shape how the Church teaches about both the good of the human person and the norms that guide human action. This text explores the basic and central elements of the theological thinking behind the encyclical. It considers the principal methodological issues and substantive questions that must shape any adequate moral theology in the post-Veritatus period.
