By Father Jerry J. Pokorsky, Catholic World Report - Every person, from king to commoner, lives by a moral code. Catholic moral theology is grounded in the Ten Commandments and the principles of Natural Law.... The Catholic Church clusters its moral precepts—Natural Law, God’s positive law, and Church discipline—around the Ten Commandments. Catholic moral theology is reasonable and governs human acts. The deliberate violation of a moral precept, with freedom and full consent, renders a person guilty. Although most sins are venial and weaken the soul, some sins are mortal and rob it of sanctifying grace. God grants His grace and the sacraments to restore that grace and return us to the path of salvation.
