I am in complete agreement, you got it down pat.
By the way, the whole “Bible was corrupted” theory is sort of disproved by the dead sea scrolls, but let’s not confuse things with facts. It is likely that there were some revisions to the Quran, however, and the originals were hidden or conveniently lost, since only a few scribblings remain. We know that the Satanic Verses were later removed, anyway.
