I'm sympathetic to sola scriptura, and I have a lot of respect for the sincere attempts by generations of Protestant Biblical scholars to go back to the original text. But there is exegesis in every reading of a text no matter how neutral it tries to be, if for no other reason than the words in the readers' heads are changing their meanings from generation to generation. Throw in the incredible complexity, not to say self-contradictions, of the many voices captured in scripture, and the idea of the consistency of the text is a foreign concept slapped onto the source material later. Scriptural consistency is itself the most radical reinterpretation of scripture. The Pentateuch, just a small portion of scripture, was rehashed over by at least 4 different editors (JEDP), each of who had an agenda that was far more aggressive and invasive than just preservation of an existing work -- they were doing a complete rewrite.
So, the original texts came from many different cultures, often unrelated to one another, and the bundling of them together was artificial. There is overwhelming textual evidence of a continuous process of re-editing, censoring, and distorting these source texts over the many years prior to their canonization. Thus, even if it were true that the Bible had been somehow stored in pristine vacuum-lock purity from the moment of the Muratorian Canon in 170 onward, which is highly dubious, we have tons of evidence of tinkering and outright rewriting in the hundreds of years before.
Even granting there is a God (there isn't) and a divine sanction for the text (there wasn't), we still have incontrovertible evidence that the text has been constantly changed to suit the needs of the believing community and power structure. Given the fate of all the other scriptures that all the other cultures have had over the millenia, that should come as no surprise. Even if God actually was the first guy on the game of telephone, the message that we have now is hopelessly garbled.
