But the manuscripts we have of the Gospel of Mark exhibit inconsistencies with each other. They don't meet a standard as high as you describe. Many of these are insignificant, to be sure, but scribal errors are thoroughly documented.
The verse that calls all scripture God-breathed refers solely to the OT, as the NT didn't yet exist.
I don't accept that any of it is God-breathed however, but just the documentation of how a given people at a given time wrestled with the idea of a god.
Correlation does not prove causation. Not everyone could afford schooling so if there are spelling errors in some of the copies you don't make my logic leap from spelling errors to "they changed the text".

Anybody can make mistakes and the fact that Vaticanus sat on the shelf for a thousand years and is in such good condition is because no one used it because everyone knew that the scribe made a mistake.
So what is your theory for why the Jesus story where he says "He who is without sin...." doesn't appear in any of the oldest manuscripts extant?
This story was a later addition to scripture that SOMEONE added.
Was that just a "mistake"? Did someone misplace it and then just found it hanging around and re-inserted it?
Like I said. They put some manuscripts aside when they made mistakes. That would account for why it wasn't included.
