"Idolatry entails putting alien gods before the true God of the Bible, worshiping something which is not divine. In the Latin American situation these gods are money, the comforts it brings, and the power necessary to make and keep it. Starting with the conquistadores and continuing for five centuries through successive ruling systems up to multinational corporations today, greed has divinized money and its trappings, that is, turned them into an absolute. Core transgressions against the first commandment have set up a belief system so compelling that it might be called moneytheism, in contrast to monotheism.
Like all false gods, money and its trappings require the sacrifice of victims. Whether the poor are offered up indirectly through the economic conditions necessary to produce profit, or directly through the violence necessary to sustain those conditions, their lives are the sacrifice. What is most insidious is the way traditional preaching and theology put a superficial veneer of Christian belief over the face of these idols...Neutral in the face of injustice, the racist, sexist, classist image of God perverts the actual contours of the living God in the service of moneyed interests" (79-80).
It won't fit on a sign. But it is to the point. I don't know if Jesus would #ows, but I wouldn't be surprised to see Sister Elizabeth there.
