I think his objection is to people who take verses out of context. Some people use the Bible like an oracle, opening it up to a random page. Some people find a verse that seems encouraging to them, or approving of their actions, without considering, what history was being told? Who was God speaking to? Does the verse apply to a specific time and place, or to all times?
To me that statement suggests that the stories in the Bible, you know, the ones we teach our children, such as the creation, Noah, Jonah, Adam and Eve are just "literature" and not Literal.
If Jesus referred to Noah (he did) Jonah (he did) and Adam and Eve (he did) as real people, then we best not try to treat those stories as anything other than the LITERAL truth.
This guy was not there. Jesus was.
