Here is Lewis's essay on the founding of the Oxford Socratic Club. I am redating this post.
"We never claimed to be impartial. But argument is. It has a life of its own. We expose ourselves, and the weakest of our party, to your fire no less than you are exposed to ours... The arena is common to both parties and cannot finally be cheated."
C. S. Lewis, "The Founding of the Oxford Socratic Club."
Engagement in real dialogue about matters of religious faith is an act of faith. One must be so sincerely convinced of what one believes that one is prepared to trust one's ideas to the forum of open intellectual dialogue, playing as fair as it is possible to play. We have to trust that dialogue will be rational even if the people who engage in it are not. Honest philosophy and theology has to come first, the conversions have to be a by-product. Though I like seeing people embrace the positions I embrace as much as the next person.
