C.S. Lewis in Mere Christianity on the importance of theology:
They all say “the ordinary reader does not want theology”…I have rejected their advice. I do not think the ordinary reader is such a fool. Theology means “the science of God”, and I think any man who wants to think about God at all would like to have the clearest and most accurate ideas about Him which are available…If you do not listen to Theology, that will not mean that you have no ideas about God. It will mean that you have a lot of wrong ones–bad, muddled, out-of-date ideas.
