Well, now, that’s silly. Some books in the Bible are absolutely historical. They may not be historical the way we think of histories, but they’re a hundred percent more historical than a lot of stuff on the History Channel. They include many historical facts, and many interpretations of historical facts, and many stories about history. This is standard for histories written in the ancient world; and the Bible has been discovered to be historically trustworthy for many purposes.
Now, if you only think of histories as being modern histories, no doubt you will also think that Thucydides is nothing but stories, and that you can’t rely on Xenophon to tell you the truth, and that Julius Caesar wrote pure fiction about the Gallic War. In which case, I’d like to know how you propose to find out anything about Greek and Roman history except archeological sites. You don’t even know the names of towns if you don’t accept “stories”. (Or travelogues and guidebooks from the ancient world, which also are full of “stories”.)
Now, the Bible does have other kinds of books besides historical chronicles. Many many kinds of books, primarily prophecy, wisdom/proverbs, and poetry.
Job is a great piece of poetry. The chances are that it was written about some famous story, which was probably based on historical stuff that happened to some guy. However, since we also believe that Job is inspired prophetic poetry, and since it is part of the Bible, we can suspect that it’s extremely, extremely true.
Look - in every country in the ancient world, everybody knew that poets dealt with legends and fictionalization. But it was also widely accepted that poets were prophets, and great poets were great prophets. Poets could understand truth and people at deep levels, see the past and predict the future. God spoke through poets. God told people the truth through poets. Poets wielding their office were a fearful thing, upholding the order of the world.
So I have very little patience for “it’s just poetry,” because in the ancient world there’s no such thing.
Now, in the Hebrew world, it was even more true. God created language. His every Word had power, and so poetry about Him had power, and wordplay had power. Job is inspired Biblical poetry, so it’s not just words on a page that sit there. The story of Job does things in the world, because the Word of God is active and not empty.
However… don’t be too hard on priests who say silly things about the Bible. Oftentimes, they don’t really mean it the way it comes out. If they downplay the Bible a lot, they may have gotten bad information in their seminary classes back in the day.
