This article will address three specific questions within a Catholic framework: 1) What is the justification for asserting that objective moral norms apply to the content of the civil law?; 2) Why is not the law's "secular" character a barrier to enactments, based on objective moral norms?; and 3) Why is not the "private" character of reproductive and other activities a barrier to the enactment of legal regulation affecting them?
