Book excerpt: The comprehensive introduction to Catholic moral theology by the leading theologian and author of The Moral Virtues and Theological Ethics. In Introduction to Moral Theology, Father Romanus Cessario, O.P. presents and expounds on the basic and central elements of Catholic moral theology written in the light of Veritatis splendor. Since its publication in 2001, this first book in the Catholic Moral Thought series has been widely recognized as an authoritative resource on such topics as moral theology and the good of the human person created in God’s image; natural law; principles of human action; determination of the moral good through objects, ends, and circumstances; and the virtues, gifts of the Holy Spirit, and the Beatitudes. The Catholic Moral Thought series is designed to provide students with a comprehensive presentation of both the principles of Christian conduct and the specific teachings and precepts for fulfilling the requirements of the Christian life. Soundly based in the teaching of the Church, the volumes set out the basic principles of Catholic moral thought and the application of those principles within areas of ethical concern that are of paramount importance today.
