YOUCAT Question n. 333 – Part V. 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 1956) The natural law, present in the heart of each man and established by reason, is universal in its precepts and its authority extends to all men. It expresses the dignity of the person and determines the basis for his fundamental rights and duties: For there is a true law: right reason. It is in conformity with nature, is diffused among all men, and is immutable and eternal; its orders summon to duty; its prohibitions turn away from offense.... To replace it with a contrary law is a sacrilege; failure to apply even one of its provisions is forbidden; no one can abrogate it entirely (Cicero, Rep. III, 22, 33). 

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 1957) Application of the natural law varies greatly; it can demand reflection that takes account of various conditions of life according to places, times, and circumstances. Nevertheless, in the diversity of cultures, the natural law remains as a rule that binds men among themselves and imposes on them, beyond the inevitable differences, common principles.
