I got another email asking: "If Job is pious fiction, I've read about other folks who think the Book of Mormon is too. What do you think of that?"
I responded: Since Moroni came to and was seen by Joseph Smith, Oliver Cowdery, David Whitmer and Martin Harris we know at least one of the book's characters was a real person. Which implies the others were also. Personally, I think they were all real people.
