Tonight we take up the subject of C S Lewis' view of what is essential in Christianity. Here is the quote we will explore. "Ever since I became a Christian I have thought the best and perhaps the only service I could do for my unbelieving neighbors was to explain and defend the belief that has been common to nearly all Christians at all times." (Preface to Mere Christianity.) To help us explore Lewis thinking is Rev. Dr. Bryan Burton, Senior Pastor of John Knox Presbyterian Church. He is joined in segment two by Jennie Spohr, an ordained Presbyterian pastor and producer of TKM and Brian Luke who was raised and educated in South Africa and is a Microsoft executive. Segment three includes audience questions and response.
