Yup, the C.S. Lewis “Lord, Liar, or Lunatic” argument. Very well thought out, however, one has to believe that Jesus said the things he is claimed to have said in the bible in order for this argument to hold water. And just so someone doesn’t jump on me with flying accusations, yes I believe Jesus said those things.
I thought that argument came from Chesterton, not Lewis, or at least from Chesterton first.
