Doctrines You Least Like

A clearly maintained distinction between what the Faith actually says and what you would like it to have said or what you understand or what you personally find helpful or think probable, forces your audience to realize that you are tied to your data just as the scientist is tied by the results of the experiments; that you are not just saying what you like. This immediately helps them to realize that what is being discussed is a question about objective fact - not gas about ideals and points of view.

The new truth which you do not know and which you need must, in the very nature of things, be hidden precisely in the doctrines you least like and least understand. It is just the same here as in science. The phenomenon which is troublesome, which doesn't fit in with the current scientific theories, is the phenomenon which compels reconsideration and thus leads to new knowledge. Science progresses because scientists, instead of running away from such troublesome phenomena or hushing them up, are constantly seeking them out. In the same way, there will be progress in Christian knowledge only as long as we accept the challenge of the difficult or repellent doctrines. A "liberal" Christianity which considers itself free to alter the Faith whenever the Faith looks perplexing or repellent must be completely stagnant. Progress is made only into a resisting material. (C. S. Lewis, Christian Apologetics)
