Karl Polanyi on the Christian roots of socialism:

Socialism is, essentially, the tendency inherent in an industrial civilization to transcend the self-regulating market by consciously subordinating it to a democratic society. It is the solution natural to industrial workers who see no reason why production should not be regulated directly and why markets should be more than a useful but subordinate trait in a free society. From the point of view of the community as a whole, socialism is merely the continuation of that endeavor to make society a distinctly human relationship of persons which in Western Europe was always associated with Christian traditions.
