Logical fallacy of false dilemma. Third option: those who wrote of him long after his death ascribed to him things he did not say or do.
Not quite. I wasn't discussing the possibility of a third option having merit -- with you or with anyone else. (Neither, in fact, was C.S. Lewis.) I was discussing Goldie Hawn's perception of Jesus as illustrated by her comments in the article. Notice that she says "when [Jesus] went to the desert" -- when, not if. She's not debating whether someone invented the story of Jesus' sojourn in the desert, she's simply interpreting the story in a nonsensical way.
C.S. Lewis's point was that people will read -- and believe -- the words attributed to Jesus in the gospels but then completely miss their significance. They believe he said he was able to forgive sins, but at the same time they say he was nothing more than a wise man. Hence the poached egg problem.
