I don't have the time nor inclination to prove that the earth is not flat again. Perhaps you should read other sources, some unbiased ones, perhaps, which would definitely prove that there was a Septuagint written hundreds of years before Christ, that there was a Bishop of Rome way before Constantine, and that Jerome accepted the Deuterocanonicals based on the Church's divinely given authority. No matter what evidence I bring out, it seems you will disregard it anyway - seeing you continue to argue such obvious errors...
Actually all you have done is assert what you believe.
There is no textual evidence for a BC Septuagint.
Nor did Jerome ever view the Apocrypha books as equal to scripture.
Until Trent, many other Catholic scholars felt the same way.
Those are simple facts.
