Back in September the Holy Father gave a brilliant address to the German Parliament on the origin of law and the ability of reason to discern what is right. I bookmarked it on my computer a while back and, after just revisiting it, I thought I'd share an excerpt here. It is so good that I found it very difficult to pull just one snippet. Every legislator in America should read this. It's a welcome dose of serious thought in an age of vapid talking points and appeals to emotions.
For the development of law and for the development of humanity, it was highly significant that Christian theologians aligned themselves against the religious law associated with polytheism and on the side of philosophy, and that they acknowledged reason and nature in their interrelation as the universally valid source of law. This step had already been taken by Saint Paul in the Letter to the Romans, when he said: “When Gentiles who have not the Law [the Torah of Israel] do by nature what the law requires, they are a law to themselves ... they show that what the law requires is written on their hearts, while their conscience also bears witness ...” (Rom 2:14f.). Here we see the two fundamental concepts of nature and conscience, where conscience is nothing other than Solomon’s listening heart, reason that is open to the language of being. If this seemed to offer a clear explanation of the foundations of legislation up to the time of the Enlightenment, up to the time of the Declaration on Human Rights after the Second World War and the framing of our Basic Law, there has been a dramatic shift in the situation in the last half-century. The idea of natural law is today viewed as a specifically Catholic doctrine, not worth bringing into the discussion in a non-Catholic environment, so that one feels almost ashamed even to mention the term. Let me outline briefly how this situation arose. Fundamentally it is because of the idea that an unbridgeable gulf exists between “is” and “ought”. An “ought” can never follow from an “is”, because the two are situated on completely different planes.
