@AffableGeek. Lewis' "Lord, Liar, or Lunatic" trilemma is (a) full of rather nasty abelism, (b) ignores a bunch of other possibilities (most obviously, that he was misreported), and (c) doesn't actually help to answer this question, even if you accept its premises. (No matter how much of a liar or "lunatic" Jesus may have been, you may still find his philosophy useful in and of itself.) —
