St. Thomas Aquinas and the Natural Law

The object of the moral act is a subject of some controversy in modern discussions of Christian ethics. Pope St. John Paul II, in the encyclical Veritatis splendor, speaks to the nature of the moral act with reference to Thomistic philosophy. This article discusses the foundational elements of Thomas Aquinas’s account of natural law and provides some important clarification of the nature of the moral act as addressed in the encyclical.
