The Church’s moral reflection, always conducted in the light of Christ, the “Good Teacher”, has also developed in the specific form of the theological science called “moral theology”, a science which accepts and examines Divine Revelation while at the same time responding to the demands of human reason. Moral theology is a reflection concerned with “morality”, with the good and the evil of human acts and of the person who performs them; in this sense it is accessible to all people. But it is also “theology”, inasmuch as it acknowledges that the origin and end of moral action are found in the One who “alone is good” and who, by giving himself to man in Christ, offers him the happiness of divine life.
Veritatis Splendor 29
The person, including the body, is completely entrusted to himself, and it is in the unity of body and soul that the person is the subject of his own moral acts. The person, by the light of reason and the support of virtue, discovers in the body the anticipatory signs, the expression and the promise of the gift of self, in conformity with the wise plan of the Creator.
