Human rights are increasingly being presented as the common language and the ethical substratum of international relations. At the same time, the universality, indivisibility, and interdependence of human rights all serve as guarantees safeguarding human dignity. It is evident, though, that the rights recognized and expounded in the [U.N. Universal] Declaration [of Human Rights] apply to everyone by virtue of the common origin of the person, who remains the high point of God’s creative design for the world and for history. They are based on the natural law inscribed on human hearts and present in different cultures and civilizations. Removing human rights from this context would mean restricting their range and yielding to a relativistic conception, according to which the meaning and interpretation of rights could vary and their universality would be denied in the name of different cultural, political, social, and even religious outlooks. This great variety of viewpoints must not be allowed to obscure the fact that not only rights are universal, but so too is the human person, the subject of those rights.
