Something great was that John, vast merit, great grace, great loftiness! Admire, by all means, admire; but as it were a mountain. But a mountain is in darkness unless it be clothed with light. Therefore only admire John that you may hear what follows, “He was not that light;” lest if, when thou thinkest the mountain to be the light, thou make shipwreck on the mountain, and find not consolation. But what oughtest thou to admire? The mountain as a mountain. But lift thyself up to Him who illuminates the mountain, which for this end was elevated that it might be the first to receive the rays, and make them known to your eyes. Therefore, “he was not that light.”
