P31W (shortened),
I think I did answer your question, do we have all of God breathed words? And if we don't is it still without error? Textually, the bible itself admits that we DO NOT have all of what God gave these writers as I noted in my article:

I think this is stark! Secondly, do we have the original texts themselves? The answer to that is no way, just the same as the Mormons do not have the gold plats given to Joseph Smith. So we, just like they, cannot prove anything about the "origional God breathed words." And the attempt to do so is not a good or practical endeavor.
You asked about "special revelation." Who said anything about "special revelations?" This is a trick of language and religious teachers to differentiate "orthodoxy" from alleged "heresy."
How do we tell the difference between what the JW's and Mormons bring from that which we have from God? Easy! All that other stuff takes away from God and a focus on what He wants to do and has demonstratably done. Holding to the bible is really no guarantee of rightness either, because what happens when we twist what scripture says or means, or misinterpret it (purposely or otherwise). In that case we are no different than outright cultists and mystery religionists.
I guess we need to ask what is the purpose for taking a pro-view of inerrancy is all about. IF we genuinely plumb the depths of that question we'll be aghast at where we end up.
As far as christian cults go, more of the accepted/orthodoxy is cultish if not a cult than those believers who reject such. Lets talk about what "cult" is and what "heresy" is and then go back and look at so-called ecclesiastical history and we'll have to make some admission we'd not like to...
P31W, no doubt many believe these things for good reasons. But medieval believers also believed sincerely, and with good purposes in mind, that the earth was flat.
