AnnetteJoan, your studying of the Hebrew Bible and Judaism is, permit me to say, a bit incomplete. In regard to the ORIGINAL Septuagint, yes, the early Jews did say it was divinely inspired, but why? The answer is that this Septuagint contained ONLY the Five Books of Moses, which are thought to be divinely inspired. Both Jewish and Christian scholars agree on this point. Later versions of the Septuagint, however, include additional books, such as the Prophets, which are those that contain the prophecies. These were added by the Church Fathers, such as Origen, but were NOT part of the initial Septuagint. So naturally these later versions written AFTER Jesus are more oriented toward the Christological aspects of Jesus as the Messiah, aspects which do not so readily appear in the original Septuagint, nor in the Masoretic Text. Further, the Dead Sea Scrolls confirm the Masoretic Text in its (near) entirety (the Scrolls themselves are fragmentary) to a remarkable degree and detail, significantly more so than the Septuagint. So your focus on the reworking of the Masoretic Text in the form of deleting references to the Messiah are quite misinformed.
