We are up to chapter 3 in our discussion of Mere Theology: A Guide to the Thought of C. S. Lewis . Here are some discussion questions to get us started on this chapter on the Trinity: Do you think Norman Pittenger's criticism of Lewis's teaching on the Trinity was fair or not? Does Lewis's explanation of how the doctrine of the Trinity developed seem reasonable? Which one of Lewis's Trinitarian analogies best helps you to understand and embrace the Christian doctrine of the Trinity: the cube? the prayer closet? the books? the relationship between imagination, image and will? love? or the Great Dance? Why? What do you think of the Trinitarian images in Lewis's fiction? Do these images make the Trinity more attractive or understandable to you? Feel free to chip in your thoughts apart from these questions, or raise a question of your own.
