He states in his blog:
In the debates about public policy, however, I know that I cannot simply quote Scripture or cite ancient theologians in order to defend my position. I do not believe that everything that is declared sinful in the Bible ought to be decalred illegal in contemporary pluralistic societies. Here we enter a more pragmatic arena where we need to explore with our fellow citizens whether we have any common assumptions about what makes for a healthy society, and whether we can then figure out a workable arrangement that can accommodate our respective moral convictions. Unfortunately, that is not an easy discussion to have in the present climate. Many of my fellow Christians simply want to condemn the idea of same-sex unions as sinful. And many defenders of those unions seem eager to use terms like “homophobia” in describing anyone who disagrees with their views. When both sides are shouting at each other, it is difficult to have a discussion that clarifies the issues.
