Dweather; "the Bible says that the word of God would be preserved". Such a statement is characteristic with the craft of the scribe who is compelled to do the work of his master. Manuscript copies are fundamentally flawed in their ability to clinically transmit the text of the original writer.
The very reason why so many stories were concocted to plead the fidelity of copyists is because it was impossible to keep texts free from alteration with the human instinct to modify one with personal or sectarian biases.
One would be naive to imagine that there is an original Bible other than the first compilation of selected texts sacralised by the Roman Catholic bishops in the fourth century. Much of which was then recently syncretized or adapted to conform to the imperial demands for an orthodoxy of belief in the Roman world. This was, after all, the very meaning of catholic, i.e. a universal all encompassing belief system, which later emperors enforced on pain of death.
"Knowledge is power" but it has always been the powerful who determine what the knowledge should be.
