Graetz is wholly discredited, and has been for a long, long time. From your own source:
In 1871 Heinrich Graetz, drawing on Mishnaic and Talmudic sources, concluded that there must have been a late 1st century Council of Jamnia which had decided the Jewish canon. This became the prevailing scholarly consensus for much of the 20th century, but from the 1960s onwards it came increasingly into question. In particular, later scholars noted that none of Graetz's sources actually mentioned books that had been withdrawn from a canon, and questioned the whole premise that the discussions of the rabbis were about canonicity at all.
And the Dead Sea Scrolls, with a very few exceptions, tend to support the Jewish notion, being for the large part a proto-masoretic collection. The very idea of 'canon' is a Greek/Roman (pagan) construct. The Jewish 'canon' would be the Torah, which is held paramount even against the rest of the Tanakh.
So you are siding against Christ with a Jewish synod that anathematized the same Septuagint scriptures that the Apostle Paul used to prove the divinity of Christ to the Bereans. Kind of ironic. ROME DID NOT CHANGE THE OLD TESTAMENT SCRIPTURES. HOW MANY TIMES DO WE HAVE TO CITE THE ANCIENT CANONS. The Council of Carthage decreed in the year 419
I find it HIGHLY unlikely that Paul, a student at the feet of Gamaliel, and quite likely a member of the Sanhedrin, was using anything but Hebrew scriptures. Again, the DSS puts to shame the idea that anything but Hebrew was being used within the Temple precinct, and calls into serious question the idea that Hebrew was a dead language at all in the first century. Rather that it was a living language, and quite likely used among the general public.
The Ethiopian Jews, for example, consider those books you and the Palestinian Jews consider "apocryphal" to be part of the Bible. http://biblescripture.net/Canon.html http://en.wikipedia.org/wiki/Dead_Sea_Scrolls#Significance_to_the_Canon_of_the_Bible
So what? Ethiopia naturally looked to Alexandria. No one would dispute that the official Hebrew Scriptures and the authority for them was undoubtedly Jerusalem.
