Though the Bible is clear about helping the poor and charity to those who are in need, it should be from willing hearts. The Bible especially speaks against those who are lazy and unwilling to work for a living, and does not support them being given welfare.
The Bible does not support forced re-distribution of wealth, from those who work to those that don't want to work. The Bible speaks against tyrannical leaders who squeeze their people of their sweat and labor.
Jesus was not a community organizer. He came to save both the rich and poor and those in between from the enslavement of sin, and provide reconciliation with God.
I think Jesus himself said this. My kingdom is not of this world. The immediately prior Pope (Benedict XVI) said Christianity is neither a political system nor an economic system.
Just about all people of good will speak to the goodness and necessity of justice and charity, but if this Pope wants a shiny sticker for this, fine. What makes the Bible remarkable in this era of “social justice,” is the following: The BIble recognizes and accepts inequality; it describes God as intending inequality; and it describes inequality as characterizing many aspect of the human condition, not just money.
