Again you are absolutely correct! The religions of "authority" while motivated to preserve truths important to them in one age, end up petrifying those truths AND adding their own speculative interpretations about those truths, speculations which ALSO become part of the now diluted and compromised truth, which is further preserved in scripture, which is further edited and refined by still other adherents to "the only truth". So we end up with what we have in the collection of Bible books, a layer cake of preservation, revision, reinterpretation, additional revelation, preservation, revision, prophecy, revision, reinterpretation, editing etc. Its exactly what we should expect to find.
The inconsistency and evolution in the so called "scripture" add to their authenticity rather than detract in my opinion. There is evidence of real confliction in the authors between the old ways and the new with the audience in mind.
The church is afraid that if you discover inaccuracies and inconsistencies in the record, that it may lead one to loose faith, when in fact their pride and cover up has lead directly to the very thing they had hoped to avoid!!! Religion lags behind in reformation, it must have change forced upon it!
