It is difficult for individualist-minded Christians to join a populist movement. This is because we want to intellectually assent, as we would to articles of faith, to the intellectual propositions of Occupy Wall Street. But popular movements are living, breathing entities.
When we join a political movement, like when we join the church, we gain brothers and sisters we are sometimes ashamed of. There are missionaries who we dislike, dogmas and creeds that we disagree with. But we are still part of the church, following Christ, for better of for worse.
