Can the Christian Left Be a Real Political Force?

If liberal Christianity is ultimately going to thrive, however, it’s hard to imagine it doing so without reviving the local churches that have been shrinking over the decades. Conservative congregations ask for serious commitment; they expect their people to show up, and they ask them to adhere to a narrower set of beliefs and behaviors. There’s a cost associated with membership. The political economist Laurence Iannaccone observed in the early 1990s that churches that ask more from their followers tend to be stronger. As an evangelical sociologist once told me, people are drawn to beliefs that make ‘demands of the flesh.’

Many progressive churches, by contrast, barely demand a pinky toe. ... The Christian left would benefit from Christian right’s urgency not just with politics but with religion itself.
