Lewis on "new" interpretations

From "Why I Am Not a Pacifist":

If Our Lord's words are taken in the unqualified sense which the Pacifist demands, we shall be forced to the conclusion that Christ's true meaning, concealed from those who lived in the same time and spoke the same language, and whom He Himself chose to be His messengers to the world, as well as from all their successors, has at last been discovered in our own time. I know there are people who will not find this sort of thing difficult to believe, just as there are people ready to maintain that the true meaning of Plato or Shakespeare, oddly concealed from their contemporaries and immediate successors, has preserved its virginity for the daring embraces of one or two modern professors. But I cannot apply to divine matters a method of exegesis which I have already rejected with contempt in my profane studies. Any theory which bases itself on a supposed "historical Jesus" to be dug out of the Gospels and then set up in opposition to Christian teaching is suspect. There have been too many historical Jesuses - a liberal Jesus, a pneumatic Jesus, a Barthian Jesus, a Marxist Jesus. They are a cheap crop of each publisher's list, like the new Napoleons and the new Queen Victorias. It is not to such phantoms that I look for my faith and my salvation.
