“...Wow!! that really doesn’t make much of an argument against Sola Scriptura...”
Sola Scriptura is a man made tradition not found in the bible. Where does the bible list its own canon? It does not.
The Alexandrian Canon used by Jesus includes the deuterocanonical books rejected by protestants. This canon is referred to by Jesus Himself in the New Testament.
The false argument that the “extra” Alexandrian canon books were only found in the Greek and not the Hebrew or Aramaic was discredited when the Dead Sea Scrolls were found and all of the books except Esther (including Maccabbees that speaks of purgatory) were found in the ancient languages.
The Jewish people did not settle their canon until after Jesus. They rejected the biblical books used by the early church (Alexandrian canon) after they had also rejected Jesus, so thier judgment is no longer valid at that point; Jesus did use the Alexandrian canon and his judgment is valid. Since Jesus used it, it is good enough for the Catholic Church.
Simply false. To the best of my knowledge, all that supports the deuterocanonical books within the DSS are four: Sirach, Tobit, Jeremiah's Epistle (Baruch 6), and Psalm 151.
One might add that there was only one copy of Sirach found, and but fragments of Tobit, While there were (around) dozens of copies of Enoch 1 and Jubilees (both rejected by western canon), and between four and dozens of every book contained within the (proto)Masoretic scriptures (excluding Esther, of course).
Likewise, one might also note that without a doubt, DSS supports the Masoretic Tradition to a very high degree...
And lastly, of all books which might be found, the most doubtful of all would be Maccabees - a book which glorifies everything the Qumran community hated.
The Alexandrian Canon used by Jesus includes the deuterocanonical books rejected by protestants. This canon is referred to by Jesus Himself in the New Testament.
Again, false. Jerusalem and environs used the Hebrew Scriptures authorized by the Temple. Synagogues used Hebrew Scriptures authorized by the Pharisees. The only people using otherwise would have been the Hellenists, who were not favored by the population at large, and certainly not by Jewish governing bodies.
