actually, this really raises the issue of what, at a bare minimum, we must get from Biblical history. On the one hand, Fundamentalists insist every freaking detail of Scripture is absolutely true in a literalistic sense, both in figures, places, chronology, statistics, etc. Hence, when one book reports there were 800 baths in a particular temple, and another account says 1800, they call in bug and crease investigators to tear through every detail and nook and crany to try to say it must reconcile. On the other hand, you have ultra liberals who essentially regard the totality of Scripture as nothing but mostly fictitious stories that are merely meant to illustrate some moral lesson and that have little or no connection to history that is real.
Firmly in between these extremes is the Church: Essentially, the overall major history of the OT is true, for God indeed needed to prepare, within human history itself, through mighty deeds and Revelation, the coming of His Incarnate Son. But the Church does not insist that Scripture is necessarily without error in regards to minor temporal details that are not directly pertinent to Salvation.
So, it is one thing to say that a date here or certain temporal details there are little inaccurate, versus, “there never was any flood, nor a calling of Abraham, nor any real major Exodus, etc.”. In regards to this, certain Early Fathers, including Augustine, seem to spell out the bare minimum great subages of OT history, which they delineate as five (hint, seems well gelled with Revelation 17 and the beast: “five have fallen”).
As Augustine spells out the five ages of the old law:
I. From Adam to Noah
II. From Noah to Abraham
III. From Abraham to David
IV. From David to the Babylonian Captivity
V. From the Captivity to Christ
and just for the record, the general data strongly suggests three ages for the Church, corresponding to the three of the Jews:
I. From Christ to Catholic Christendom
II. From Catholic Christendom to the Coming Age of Peace (Millennium of Rest)
III. From the Age of Peace to the New Creation (Christ again, i.e., Second Coming)
