who have wounded eyes are able to see a wall illuminated and enlightened by the sun, or a mountain, or a tree, or anything of that sort; and, by means of another body illuminated, that arising is shown to those who are not as yet able to gaze on it. Thus, therefore all those to whom Christ came were not fit to see Him: upon John He shed the beams of His light; and by means of him confessing himself to have been irradiated and enlightened, not claiming to be one who irradiates and enlightens, He is known who enlightens, He is known who illuminates, He is known who fills. And who is it? “He who lighteth every man,” he says, “who cometh into the world.” For if man had not receded from that light, he would not have required to be illuminated; but for this reason has he to be illuminated here, because he departed from that light by which man might always have been illuminated.
