Summary of Catechism paragraphs 1949-1986:
- The moral law arises from God’s Wisdom; reflecting the harmonious beauty of His design for us, it points out the right path for us to take for our own good, and our ultimate happiness in eternal life.
- Its elemental expression is “natural law,” referring to the moral compass inscribed within human nature and discernible by our reason.
- Implanted in our hearts by God, natural law serves as the building block of civil law and social norms of morality.
- But since our human nature has been wounded by sin, our ability to discern this natural law readily, and with clarity, has been weakened as well.
- God, ever desirous of drawing us to Himself, has devised another expression of His Law, through divine revelation; as St Augustine phrased it, “God wrote on the tables of the Law what men did not read in their hearts.”
- The first stage of this revealed Law was given to the people of Israel: the Law of Moses, enshrined in the Ten Commandments, builds on natural law and teaches us about right and wrong.
- Although the Law of Moses defines sinful behavior, it does not strengthen us to overcome it; hence the Old Law serves as a preparation for the fullness of revelation in Christ.
- Christ gives us the New Law, the perfection of divine Law on earth; He fulfills the Law of Moses by deepening the meaning of the Ten Commandments and by purifying our hearts.
- The Law of the Gospel is a Law of love; of grace, for we are empowered by the Holy Spirit and the sacraments to live accordingly; and of freedom as God’s children, not as slaves.
- Expressed most vividly in the Sermon on the Mount, the New Law is summed up in the Golden Rule, “Do to others whatever you would have them do to you,” and even more profoundly in Jesus’ new commandment, “Love one another as I have loved you.”
Live Your Faith
The moral law is not a mere checklist of rules, imposed upon us from without.
Rather, it is deeply bound up in our design as human beings: we were created to live in intimacy with God, Whose perfect holiness is reflected in the moral law.
When we sin, we violate this very order within us, in ways that are self-defeating and self-destructive. But we have a sure way out through the grace of God, Who heals us and strengthens us.
As we grow in union with Christ, we become more like Him, and experience greater freedom to live the moral life that is best for us.
