Nope...I'm not the one who is confused here. You stated:
It is obvious that the "Scriptures" to which Paul referred in his letter to Timothy mean the traditional Jewish Scripture that they kept in their synagogues, studied, used and obeyed because they came FROM Almighty God. We know for a fact that the Jewish Scripture NEVER included those Apocryphal books - they weren't even written in Hebrew which WOULD have been the case for any writings the Jews kept in their temple/synagogues. If you say you have to accept Paul's judgment, then accept that he would NOT have meant those extra-biblical books as Divinely-inspired Scripture. There IS a difference!
For a well done article on the Apocrypha, the Septuagint and the Canon, please read The Apocrypha, And Why It's Not Scripture
Indeed, but according to some Catholics, even some writings from some so-called church "fathers" and infallble pronouncements are inspired of God just like Scripture is - or they fail to make any real distinction - while this is rejected by other Catholics. Thus this issue needs to be clarified. Is plenary Divine inspiration restricted to the words of Scripture or do certain writings of church "fathers" and infallible pronouncements enjoy the same?
And it remains that
“No two Septuagint codices contain the same apocrypha, and no uniform Septuagint ‘Bible’ was ever the subject of discussion in the patristic church. In view of these facts the Septuagint codices appear to have been originally intended more as service books than as a defined and normative canon of Scripture,” (E. E. Ellis, The Old Testament in Early Christianity [Baker 1992], 34-35.
British scholar R. T. Beckwith states, Philo of Alexandria's writings show it to have been the same as the Palestinian. He refers to the three familiar sections, and he ascribes inspiration to many books in all three, but never to any of the Apocrypha....The Apocrypha were known in the church from the start, but the further back one goes, the more rarely are they treated as inspired. (Roger T. Beckwith, "The Canon of the Old Testament" in Phillip Comfort, The Origin of the Bible [Wheaton: Tyndale House, 2003] pp. 57-64)
Manuscripts of anything like the capacity of Codex Alexandrinus were not used in the first centuries of the Christian era, and since in the second century AD the Jews seem largely to have discarded the Septuagint…there can be no real doubt that the comprehensive codices of the Septuagint, which start appearing in the fourth century AD, are all of Christian origin.
Nor is there agreement between the codices which the Apocrypha include...Moreover, all three codices [Vaticanus, Sinaiticus and Alexandrinus], according to Kenyon, were produced in Egypt, yet the contemporary Christian lists of the biblical books drawn up in Egypt by Athanasius and (very likely) pseudo-Athanasius are much more critical, excluding all apocryphal books from the canon, and putting them in a separate appendix. (Roger Beckwith, [Anglican priest, Oxford BD and Lambeth DD], The Old Testament Canon of the New Testament Church [Eerdmans 1986], p. 382, 383; http://triablogue.blogspot.com/2008/01/legendary-alexandrian-canon.html)
Likewise Gleason Archer affirms,
Even in the case of the Septuagint, the apocryphal books maintain a rather uncertain existence. The Codex Vaticanus (B) lacks [besides 3 and 4] 1 and 2 Maccabees (canonical, according to Rome), but includes 1 Esdras (non-canonical, according to Rome). The Sinaiticus (Aleph) omits Baruch (canonical, according to Rome), but includes 4 Maccabees (non-canonical, according to Rome)... Thus it turns out that even the three earliest MSS or the LXX show considerable uncertainty as to which books constitute the list of the Apocrypha.. (Archer, Gleason L., Jr., "A Survey of Old Testament Introduction", Moody Press, Chicago, IL, Rev. 1974, p. 75; http://www.provethebible.net/T2-Integ/B-1101.htm)
The German historian Martin Hengel writes, “Sinaiticus contains Barnabas and Hermas, Alexandrinus 1 and 2 Clement.” “Codex Alexandrinus...includes the LXX as we know it in Rahlfs’ edition, with all four books of Maccabees and the fourteen Odes appended to Psalms.” “...the Odes (sometimes varied in number), attested from the fifth century in all Greek Psalm manuscripts, contain three New Testament ‘psalms’: the Magnificat, the Benedictus, the Nunc Dimittis from Luke’s birth narrative, and the conclusion of the hymn that begins with the ‘Gloria in Excelsis.’ This underlines the fact that the LXX, although, itself consisting of a collection of Jewish documents, wishes to be a Christian book.” (Martin Hengel, The Septuagint as Christian Scripture [Baker 2004], pp. 57-59)
Also,
The Targums did not include these books, nor the earliest versions of the Peshitta, and the apocryphal books are seen to have been later additions, and later versions of the LXX varied in regard to which books of the apocrypha they contained. “Nor is there agreement between the codices which of the Apocrypha include. (Eerdmans 1986), 382.
And Cyril of Jerusalem, whose list rejected the apocrypha (except for Baruch) exhorts his readers to “read the Divine Scriptures, the twenty-two books of the Old Testament, these that have been translated by the Seventy-two Interpreters,” the latter referring to the Septuagint but not as including the apocrypha. (http://www.bible-researcher.com/cyril.html)
And if quoting from some of the Septuagint means the whole is sanctioned, then since the Psalms of Solomon, which is not part of any scriptural canon, is found in copies of the Septuagint as is Psalm 151, and 3 and 4 Maccabees (Vaticanus [early 4th century] does not include any of the Maccabean books, while Sinaiticus [early 4th century] includes 1 and 4 Maccabees and Alexandrinus [early 5th century] includes 1, 2, 3, and 4 Maccabees and the Psalms of Solomon), then we would be bound to accept them as well.
Also, saying the church and church fathers recognized the deuterocanonicals from early one fails to admit that this was not a universally accepted, or a settled canon.
As the the Catholic Encyclopedia states,
At Jerusalem there was a renascence, perhaps a survival, of Jewish ideas, the tendency there being distinctly unfavourable to the deuteros. St. Cyril of that see, while vindicating for the Church the right to fix the Canon, places them among the apocrypha and forbids all books to be read privately which are not read in the churches. In Antioch and Syria the attitude was more favourable. St. Epiphanius shows hesitation about the rank of the deuteros; he esteemed them, but they had not the same place as the Hebrew books in his regard. The historian Eusebius attests the widespread doubts in his time; he classes them as antilegomena, or disputed writings, and, like Athanasius, places them in a class intermediate between the books received by all and the apocrypha. The 59th (or 60th) canon of the provincial Council of Laodicea (the authenticity of which however is contested) gives a catalogue of the Scriptures entirely in accord with the ideas of St. Cyril of Jerusalem. On the other hand, the Oriental versions and Greek manuscripts of the period are more liberal; the extant ones have all the deuterocanonicals and, in some cases, certain apocrypha.
The influence of Origen's and Athanasius's restricted canon naturally spread to the West. St. Hilary of Poitiers and Rufinus followed their footsteps, excluding the deuteros from canonical rank in theory, but admitting them in practice. The latter styles them "ecclesiastical" books, but in authority unequal to the other Scriptures. St. Jerome cast his weighty suffrage on the side unfavourable to the disputed books... (Catholic Encyclopedia, Canon of the Old Testament, eph. mine)
● The Catholic Encyclopedia also states as regards the Middle Ages,
In the Latin Church, all through the Middle Ages [5th century to the 15th century] we find evidence of hesitation about the character of the deuterocanonicals. There is a current friendly to them, another one distinctly unfavourable to their authority and sacredness, while wavering between the two are a number of writers whose veneration for these books is tempered by some perplexity as to their exact standing, and among those we note St. Thomas Aquinas. Few are found to unequivocally acknowledge their canonicity. The prevailing attitude of Western medieval authors is substantially that of the Greek Fathers. The chief cause of this phenomenon in the West is to be sought in the influence, direct and indirect, of St. Jerome's depreciating Prologus (http://www.newadvent.org/cathen/03267a.htm)
This issue has been settled many times by the RC propaganda continues.
What Jews kept in their temples is not relevant to what Christians realize that inspired. We, for example realize the Gospels and Epistles as inspired. The Jews put St. Paul to jail and ultimately engineered his execution for writing his letters. No wonder he wrote in Greek, the language of the Septuagint.
If St. Paul meant to say something like "Scripture in Hebrew" or "Scripture the Jews use in synagogues", or something similar to what you want to put in his mouth, he would have said that; he was not tongue-tied. He instead said "all scripture" -- not this and that scripture, and he said "known" not "approved by the Jews". Read the Scripture and respect it. Please. All of it.
