When we examine the Christian interpretation of images, what strikes us at once is that fact that the opposition, light-dark, is polarized in all these images.  The metaphysical split in the god-image of Christianity, which sees God as the summum bonum and excludes evil from the image, ascribing it either to man or to the devil, runs through the whole field of ontology.  Just as Christ represents the incarnation of the good God, so the Antichrist represents the power of evil.  Hence all images can refer, at one and the same time, either to Christ or the devil.  P&R 47
