The author did his best given the task he set for himself, that being trying to define the minimum doctrine that might represent as wide as spectrum of people professing faith in Jesus Christ. However he did not insist on sola fide and sola scriptura, so for all his effort he left real Christianity out of the discussion. Also, his latest revision was in the 1950s so both the building of the Berlin Wall and the final, absolute evidence of Marx and Engel's failure in the fall of said wall, not to mention the USSR's breakdown and dissolution, was not in evidence for Mr. Lewis so his positive view of Marxists being "advanced" he could not know was laughable. For his time though, Mr. Lewis provided Britain the encouragement they needed in their time of great crisis.
I have read the Mere Christianity part of the two-book volume. C.S. Lewis is at his finest in this book. Originally delivered as a series of radio talks to servicemen in England just after WWII, the text is an edited transcription of these broadcasts. As such, it is divided up into many little chapters of about six pages each (about 20 minutes of airtime). Relaying his thoughts in a conversational manner, Prof. Lewis starts out at the beginning assuming the reader/listener has no knowledge or belief in Christianity at all. He then progresses logically through reasons to believe, giving examples from the recent war, philosophy, history, and his own journey from atheism to Christianity. This book should be in every Christian's personal library.
