Mark Noll, quoted in the “Faith and Healthy Democracy” report with these surprising words (though perhaps they shouldn’t be):

I do not think that Christian believers, particularly in a large culturally pluralistic society, should ever expect to have Christian unity on public policy. Christian values need to be expressed and worked out in life situations. Life situations are always colored by historical forces, cultural assumptions, social realities. And because historical forces, cultural values, and social realities are going to be different for different communities, Christian teaching by its plentitude is going to nurture in different ways communities that have these historical, cultural, and social differences.
