Here is something that I think I understand (unless I don’t):
There are NO KNOWN original texts of any part of the Bible. The ancient manuscripts were copied and re-copied and re-re-copied, etc. – And throughout history (especially during ancient history), the copyists did not necessarily hesitate to do some re-editing as well, according to their doctrine or ideology or their own interpretations, or the political propaganda needs of the time and place. All of the “ancient manuscripts” we have today are those copies, many times removed from the originals. ETA: Even if they didn’t edit the text, they often added additional commentary, which later copyists (deliberately or otherwise) then incorporated into the text.
Serious biblical scholars, therefore, understand that the Bible we have today is a corrupted version of whatever God originally divinely dictated to the inspired writers. That is exactly why they have such an obsession with finding and studying as many ancient manuscripts as possible, to best reconstruct as nearly as possible what the original text may have been.
Many editions of the Bible have a phrase on the title page something like “…with all the ancient manuscripts carefully compared…” or some such. Some editions have all those footnotes indicating how a particular word or phrase appeared in various other manuscripts.
Serious scholars hold periodic international symposiums, where they argue and debate every little phrase that’s in doubt, pray for divine guidance, and then vote on which wording they believe best re-captures the original. Whoda thunk Bible text would depend on modern democratic majority rules?
Thus, serious thoughtful believers should also understand that the Bible today may contain errors, inaccuracies, and contradictions, and they could simultaneously believe, without contradiction, that the original Bible was inerrant and infallible. But even that is beyond the cognitive skills of many small-minded Bible-thumping fundamentalist preachers and their congregants, as described in some of the posts above.
Serious scholars, they ain’t.
