So, to arms! Here are a few quotes:
When Christians and other people of good will talk about "the dignity of the human person" and "the sanctity of human life," they're putting into words what we all instinctively know – and have known for a very long time. Something elevated and sacred in men and women demands our special respect. When we violate that human dignity, we do evil. When we serve it, we do good. And therein lies one of many ironies. We live in a society that speaks persuasively about protecting the environment and rescuing species on the brink of extinction. But then it tolerates the killing of unborn children and the abuse of human fetal tissue as lab material.
There's a proverb worth remembering here: "To a man with a hammer, every problem is a nail." If modern man is scientific man, technology is his hammer. But every problem isn't a nail. Knowledge without the virtues of wisdom, prudence, and, above all, humility to guide it is not just unhelpful. It's dangerous.
Science involves the study of the material world. But human beings are more than the sum of their material processes. Trying to explain the human person with thinking that excludes the reality of the spiritual, the dignity of the religious, and the possibility of God simply cripples both the scientist and the subject being studied – man himself. To put it another way, we can destroy what we mean by humanity while claiming, and even intending, to serve it.
Most of us here tonight believe that we have basic rights that come with the special dignity of being human. These rights are inherent to human nature. They're part of who we are. Nobody can take them away. But if there is no Creator, and nothing fundamental and unchangeable about human nature, and if "nature's God" is kicked out of the conversation, then our rights become the product of social convention. And social conventions can change. So can the definition of who is and who isn't "human."
The irony is that modern liberal democracy needs religion more than religion needs modern liberal democracy. American public life needs a framework friendly to religious belief because it can't support its moral claims about freedom and rights with secular arguments alone. In fact, to the degree that it encourages a culture of unbelief, liberal democracy undermines its own grounding. It causes its own decline by destroying the public square's moral coherence.
