Your Particular Judgment will, to put it mildly, be interesting.
The Latins to their detriment never accepted the canons of the Sixth Ecumenical Council, and thus point to the Seventh and a papal assent to the Council of Carthage.
Nonetheless, the conclusion is the same: the entire Septuigent is a part of the canon of Holy Scripture, and has been since the Church decided which books should be read in the Church.
Incidentally, I'm not sure what to make of your screen name. I don't think one of the sons of Feanor is someone after whom I'd name myself. Not exactly a wholesome bunch, even if they were High Elves.
