In the present day, American politics has become deeply entangled confluence with materialist, grand-scale Protestantism. To great aggravation, Christianity has been tied not only to constitutional self-governance (as this recent best-selling painting shows in a way that strongly resembles parody), but the laissez-faire economic system that has segregated its people and eroded liberty over the past two centuries. It has been used to argue for capital punishment, and for centuries has been used to create the idea of "just war"
The issue is that Jesus was not a fan of exploitative commerce. In fact, he led the first occupation- he was the founder of Occupy Jerusalem. In the gospels, he enters the Temple of Jerusalem, where commerce has defiled the holy place. He takes those around him to task, and uses the popular support for his actions to defy authority.
On reaching Jerusalem, Jesus entered the temple area and began driving out those who were buying and selling there. He overturned the tables of the money changers and the benches of those selling doves (Mark 11:15)
Later Jesus calls the Temple he cleared a "den of robbers" (Mark 11:17)
We can all learn from the example of Jesus. The idea of commerce and profit-making entering a place of worship is cringe-worthy- and indeed I have a visceral reaction when I read about megachurches with cafés and merchandise stores. But even if you're mostly secular like me- there is something that you think should not be messed with; something that must remain pure and not tainted by money. It could be anything from politics to college sports; from education to healthcare. You probably know of some money changers you'd like to drive out.
And that's really what Occupy is all about. Driving away the money changers, and improving society rather than let profit dominate over people.
