Hey..you were the one who asserted:
That's why I replied,
No, you cannot what? Admit that Trent attached the Apocrypha/Deuterocanonicals to the Divinely-inspired Old Testament canon and that is why you defend them? Or, no, you cannot identify what Apocryphal books were included in the Septuagint in Paul's day and, therefore, you cannot say with any surety Paul meant any of them were part of sacred inspired Scripture ?
Let's not forget that it was your contention that Paul's use of the phrase "all Scripture is given by inspiration of God" in his letter to Timothy meant the Septuagint - and all the books that were part of it. Seeing as you aren't under oath and giving a deposition, I don't see how asking you to clarify yourself is a negative request. If you can't defend your statement or you want to reword or retract it, by all means please do so.
It is often the case that we read something in the scripture and not fully know the context; yet we obey the scripture as written, including admitting that if some detail is not provided then it is not necessary. The exact composition of “the scripture” is not given by St. Paul, but the qualification “known to thee since infancy” is given. Therefore, however imprecise the composition of the Septuagint was copy to copy (remember, they were not physically one object as modern books are), what was important to st. Paul is that the Septuagint is inspired in any of its configurations.
The issue of canon of the Old Testament did not concern the Church till about 3rd century. we see some fathers approve of the Deuterocanon and others disapprove. Prior to that, the Church was mostly concerned with the provenance and authenticity of the New Testament books. When the Church concerned herself with this issue, she worked out the canon by the early 5 c. The Council of Carthage is evidence that the matter was settled.
