Christianity and Marxism are not merely alternative theories about economics and governance; they are rival religions, resting on mutually exclusive claims about metaphysics, morality, and eschatology. One begins with “In the beginning, God . . .”; the other with “In the beginning, there was nothing. . . .” One exalts the triune Creator as the source of authority and blessing; the other enthrones an atheistic State as the final arbiter of law, conscience, and property.
