Can you imagine when the last apostle was gone and the wars that took place and how many were killed for processing copies or even original or seal of approval!
I cringe at how many scared manuscripts were destroyed or burn!
Such is the stuff of imagination ... or speculation (at best).
Do you not believe that God would be able to protect His scriptures ?
I think history speaks for that and manuscripts were burn and just asked Tyndale?
there are others and more is starting to surface!
Do you believe there are no outright contradictions and changes (some simply due to copy errors, some deliberate changes over the various iterations) contained in the current Bible(s)?
