YOUCAT Question n. 333 – Part VI. Is there a natural law that everyone can know?

(Youcat answer - repeated) If people are to do good and avoid evil, certainty about what is good or evil must be inscribed within them. In fact there is such a moral law that is, so to speak, “natural” to men and can be known in principle by every person by reason.

A deepening through CCC

(CCC 1958) The natural law is immutable and permanent throughout the variations of history (Cf. GS 10) it subsists under the flux of ideas and customs and supports their progress. The rules that express it remain substantially valid. Even when it is rejected in its very principles, it cannot be destroyed or removed from the heart of man. It always rises again in the life of individuals and societies: Theft is surely punished by your law, O Lord, and by the law that is written in the human heart, the law that iniquity itself does not efface (St. Augustine, Conf. 2, 4, 9: PL 32, 678).

Reflecting and meditating 

(Youcat comment) The natural moral law is valid for everyone. It tells men what fundamental rights and duties they have and thus forms the real foundation for life together in the family, in society, and in the State. Because our natural knowledge is often troubled by sin and human weakness, a person needs God’s help and his Revelation in order to stay on the right path.

(CCC Comment)

(CCC 1959) The natural law, the Creator's very good work, provides the solid foundation on which man can build the structure of moral rules to guide his choices. It also provides the indispensable moral foundation for building the human community. Finally, it provides the necessary basis for the civil law with which it is connected, whether by a reflection that draws conclusions from its principles, or by additions of a positive and juridical nature.
