Truth or fiction -- that is an overly simplistic division if I ever saw one. Fiction expresses truth about life that is difficult to express with non-fiction. And non-fiction is filled with illusionary forms of reality like ideology. What the disjunct is doing is opposing a literary genre (fiction) with a truth value (truth). That already expresses an ideology that only non-fiction can express truth. In point of fact, the Bible contains a range of literary genres -- including fiction. The book of Jonah is pure fiction as I previously showed in the forum; it is a satire, and like any ancient satire it has a serious point. It uses comedy to give a searing critique of the prophetic profession. By giving us the improbable example of a prophet who is simultaneously the worst of all time and the most successful of all time, the author is able to show us what he considered to be the moral flaws of the prophets of his own day. In my opinion, fundamentalists who see in Jonah a story that must be defended as a literal 100% historical report (such as trying to prove that a man could really be eaten by a fish and survive) completely miss the point of the story.
In contrast to this, there are the more purely historiographical works like 2 Kings, 2 Chronicles, Ezra-Nehemiah, 1 Maccabees (in the Roman Catholic deuterocanon), Acts, etc. These compare rather well with other exemplars of ancient historiography. But these two have varying elements of ideology and "spin"; the authors of all of these have an agenda, and they present history only in one particular light.
And what is a "fulfilled prophecy"? Do you mean instances in which a description of past events is attributed to a figure who lived centuries before (as in Daniel and pseudepigrapha like 1 Enoch, the Assumption of Moses, the Sibylline Oracles, etc.)? Or instances in which an anonymous prophetic writing was later copied onto a scroll containing a much older prophecy like the case of Deutero-Isaiah in Isaiah (in which case the "fulfilled prophecies" weren't even intended to be predictions, but were simply references to the author's own time). Or instances in which later authors were literarily influenced by the older prophecies and composed their stories with an eye to "fulfill" the prophecies (such as the author of Aramaic Daniel making a Mede responsible for the overthrow of Babylon [cf. Isaiah 13:17-19] or the gospel writers freely taking passages out of the OT out of context to make them "prophesy" Jesus [cf. the use of Jeremiah 31:15 in Matthew 2:18, although the original passage has an entirely different meaning])? Or other "fulfillments" that are similarly created through eisgetical interpretation (such as the Society's references to the events of 1914, the League of Nations, etc. as "modern-day fulfillments" of prophecy)? When I look at the gamut of prophetic interpretation in Jewish and Christian tradition, I see a whole series of "unfulfilled prophecies" that are reinterpreted over and over again to make them fulfilled. Tyre is not uninhabited to this day, Egypt was not made completely uninhabited, Antiochus IV did not launch a third campaign against Egypt, the "end of the world" and the resurrection did not occur in the second century BC, the "end of the world" and the judgment of the righteous and wicked (with the Son of Man seen coming on the clouds of heaven) did not occur within the lifetime of those who heard Jesus, the battle of Armageddon and the fall of Rome did not occur in the lifetime of John of Patmos, etc. Although there is an Deuteronomistic ideology that true prophets must have their words come true, the reality is that unfulfilled prophecies by "true prophets" (i.e. prophets believed to have been genuinely commissioned by God on account of their moral or religious stance) were readily tolerated, as these could easily be taken as fulfilled in some other more obscure, esoteric way, or fulfilled at some later time in the future. This is especially the case with the prophets' failed hopes for the glorious restoration of Israel -- these are continually deferred to the future. The Society's paradise-earth eschatology is entirely made up of unfulfilled prophecies that have continually been deferred for over two thousand years and which can be deferred indefinitely as long as there are future days to come.
