Tim Keller, in his three books, Reason for God, Generous Justice and Every Good Endeavor, markets Marxism as Democratic Socialism. Democratic Socialism rests on certain values. Values that we as Christians understand and often embrace: caring for the poor, feeding the hungry, helping the homeless, medical care for the sick. Democratic Socialists takes care of people and as Christians we want to take care of people, right? But Keller’s love for Karl Marx is rather disguised, dodgy, and suspect. Trying to cut and paste Marxism so that it fits into a biblical worldview is not only wrong and dangerous, it’s terrifyingly deceptive.
