We have already spoken, in the first chapter, on the identities existing in all the religions of the world, and we have seen that out of a study of these identities in beliefs, symbolisms, rites, ceremonies, histories, and commemorative festivals, has arisen a modern school which relates the whole of these to a common source in human ignorance, and in a primitive explanation of natural phenomena. From these identities have been drawn weapons for the stabbing of each religion in turn, and the most effective attacks on Christianity and on the historical existence of its Founder have been armed from this source. On entering now on the study of the life of the Christ, of the rites of Christianity, its sacraments, its doctrines, it would be fatal to ignore the facts marshalled by Comparative Mythologists. Rightly understood, they may be made serviceable instead of mischievous. We have seen that the Apostles and their successors dealt very freely with the Old Testament as having an allegorical and mystic sense far more important than the historical, though by no means negating it, and that they did not scruple to teach the instructed believer that some of the stories that were apparently historical were really purely allegorical. Nowhere, perhaps, is it more necessary to understand this than when we are studying the story of Jesus, surnamed the Christ, for when we do not disentangle the intertwisted threads, and see where symbols have been taken as events, allegories as histories, we lose most of the instructiveness of the narrative and much of its rarest beauty. We cannot too much insist on the fact that Christianity gains, it does not lose, when knowledge is added to faith and virtue, according to the apostolic injunction.[158] Men fear that Christianity will be weakened when reason studies it, and that it is "dangerous" to admit that events thought to be historical have the deeper significance of the mythical or mystical meaning. It is, on the contrary, strengthened, and the student finds, with joy, that the pearl of great price shines with a purer, clearer lustre when the coating of ignorance is removed and its many colours are seen.
