From Yours, Jack:

“You see, the question about Jonah and the great fish does not turn simply on intrinsic probability. The point is that the whole Book of Jonah has to me the air of being a moral romance, a quite different kind of thing from, say, the account of King David or the New Testament narratives, not pegged, like them, into any historical situation.

“In what sense does the Bible ‘present’ this story ‘as historical’? Of course it doesn’t say ‘This is fiction’: but then neither does Our Lord say that His Unjust Judge, Good Samaritan, or Prodigal Son are fiction. (I would put Esther in the same category as Jonah for the same reason.)” (201)
