Obama on Decision making in a Democratic Society - 2006 speech

Democracy demands that the religiously motivated translate their concerns into universal, rather than religion-specific, values. It requires that their proposals be subject to argument, and amenable to reason. I may be opposed to abortion for religious reasons, but if I seek to pass a law banning the practice, I cannot simply point to the teachings of my church or evoke God's will. I have to explain why abortion violates some principle that is accessible to people of all faiths, including those with no faith at all.

Now this is going to be difficult for some who believe in the inerrancy of the Bible, as many evangelicals do. But in a pluralistic democracy, we have no choice. Politics depends on our ability to persuade each other of common aims based on a common reality. It involves the compromise, the art of what's possible. At some fundamental level, religion does not allow for compromise. It's the art of the impossible. If God has spoken, then followers are expected to live up to God's edicts, regardless of the consequences. To base one's life on such uncompromising commitments may be sublime, but to base our policy making on such commitments would be a dangerous thing. And if you doubt that, let me give you an example.

We all know the story of Abraham and Isaac. Abraham is ordered by God to offer up his only son, and without argument, he takes Isaac to the mountaintop, binds him to an altar, and raises his knife, prepared to act as God has commanded.

Of course, in the end God sends down an angel to intercede at the very last minute, and Abraham passes God's test of devotion.

But it's fair to say that if any of us leaving this church saw Abraham on a roof of a building raising his knife, we would, at the very least, call the police and expect the Department of Children and Family Services to take Isaac away from Abraham. We would do so because we do not hear what Abraham hears, do not see what Abraham sees, true as those experiences may be. So the best we can do is act in accordance with those things that we all see, and that we all hear, be it common laws or basic reason. read it all here
