You might think it is an excuse, Satanus... but Christ said that it is the Spirit who will guide and teach us. One cannot understand the scriptures without the Spirit. Nowhere does He say that one cannot understand the Spirit without the scriptures.
As to the rest, we know that would have happened, because it did (and does) happen with just the bible. People owning one were killed for it (or is that a lie?). The bible was read in latin (what purpose would that serve anyone who did not speak latin). It was a source of power... the 'word of god'. And it did give power to men who lorded that power over others. We also know that there are as many different interpretations of the written word as there are variations of christians. Some use those words to hate and to hurt; some use them to love and to show compassion.
Peace,
