Jim Wallis is the founder of the social justice organization Sojourners. In the November 2011 issue of their publication he tells the story of how Sojourners began.
He and a core group met at Trinity Evangelical Divinity School in the northern suburbs of Chicago in 1971. Wallis says that many of them had decided to attend Trinity to argue with their own evangelical tradition as to what the Bible really says.
One way they did this was by finding every verse they could locate in the Bible about the poor, wealth, poverty, and social justice. They started in Genesis and worked their way through Revelation. Every time they found a passage on one of these topics they took their scissors and cut it out. (That may shock you. Does it help that they used an old Bible?)
