The issue is what is commonly called "systematic injustice" — sources of unnecessary human misery created by unjust political, economic, and social systems. . . . This is what the political passion of the Bible is about. Its major voices protest the systemic injustice of the kingdoms and empires that dominated their world. They do so in the name of God and on behalf of the victims — slaves in Egypt, exiles in Babylon, exploited peasants in the time of the monarchy and again in the times of Jesus, and the most vulnerable in all times — widows, orphans, the poor, and the marginalized. And in the name of God, the major figures of the Bible advocate a very different vision of our life together.
