From Malanga in City Journal, a quote:
The new Religious Left is in one sense not new at all. It draws its inspiration from the Christian social-justice movement that formed in the mid-nineteenth century as a response to the emerging industrial economy, which many religious leaders viewed—with some justification—as brutal and unfair to workers. In America, the movement gained traction thanks largely to the efforts of Baptist minister Walter Rauschenbusch, who served New York City’s poor. Unlike nineteenth-century reformers who sought to help the poor by teaching them the bourgeois virtues of hard work, thrift, and diligence, Rauschenbusch believed that the best way to uplift the downtrodden was to redistribute society’s wealth and forge an egalitarian society. In Christ’s name, capitalism had to fall. “The Kingdom of God is a collective conception,” Rauschenbusch wrote in Christianity and the Social Crisis, politicizing the Gospel’s message. “It is not a matter of getting individuals to heaven, but of transforming the life on earth into the harmony of heaven.”
Sounds like Obama. The whole thing, The Religious Left, is here.
I suspect this is a vocal, but not sizeable, group of people who will be given good media access despite their "theocratic" inclinations. The "Social Gospel," it seems to me, has very little to do with Christianity, which concerns itself with matters of the spirit and saving souls, and thus largely rejects earthly concerns about things like power as vain distractions and temptations. I would steer clear of churches that do politics, and I believe that Dr. Dobson (who is truly wise on the subject of Christian child-rearing) is similarly foolish to get involved in political matters. It should be beneath their dignity.
