If he runs, I’m voting for him, for several reasons. But, I think he made a great point in his “Call to Renewal” (for Sojourners) 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.
Of course, this is a hot issue. I definitely tend to agree with Hauerwas in his approach toward abortion, BUT not in his approach toward political involvement. So, I think Volf is right, Hauerwas has nothing helpful to say about this.
