William E. May writing at the Culture of Life Foundation:
Although the name is new, the reality is that for centuries there has been an ethical/moral discipline known as “medical ethics,” with a rich tradition in the Catholic Church and also in medieval Jewish and Islamic cultures. What is even more important is the fact that the normative principles and norms of the natural law, especially the natural law as “fulfilled” and perfected by the “new law” of the Gospel, are those that enable persons of upright conscience to make good moral judgments and choices regarding the issues debated among contemporary bioethicists.
