First, we need to note that what Lewis considered "good" was heavily influenced - even defined by - his religion. Yes, that applies to most religious people. But the point remains.Mark Chance said:I don't see how anyone can reach that conclusion if they've honestly studied his theological works. Lewis was certainly Christian, and he certainly believed Christianity was the most true system of belief, but he was hardly unable to admit that there is a great deal of good to be found in almost all systems of belief.
Look at the example of Emeth. There may have been "good" in him, but not in the religion he followed.
