This is incorrect. There were a number of competing canons in the first century AD, ranging from the Sadducees' canon (which was just the 5 books of the Torah) to the Septuagint canon (46 books). There was vigorous debate between Beth Shammai and Beth Hillel over the Chronicles and the Song of Songs, and so forth. A twenty-four book canon is mentioned in the Midrash Koheleth. Both Jesus and His Apostles accepted the full Septuagint canon, since 85% of the OT verses quoted in the NT are quoted directly from the Septuagint.
This was the situation confronting the anti-Messianic faction of the Jews led by Rabbi Yohanan ben Zakkai. After the Temple was destroyed they were facing an existential threat, being increasingly challenged by the growing Messianic (Christian) movement. Whether at a hypothetical Jewish Council of Yavneh/Jamnia or elsewhere, Yohanan ben Zakkai and his halachic school eventually came up with their own canon (an anti-Messianic canon) sometime between 90 AD and 100 AD.
This scaled-down canon included 39 books and excluded 34 books. All of excluded books were written in Greek: the 7 Deutercanonicals and the entire collection of 27 more books we now know as the New Testament. (Whether John 1, 2, 3 and Revelation had been written yet I do not know, but I am including them in the count because they were all excluded by the circa 90 AD rabbinical reaction against Christianity.)
They excluded them because they supported so directly to the beliefs and practices of the rival Christian community.
The limitation of the TaNaKh to the 39 Hebrew manuscripts, while accepted by the anti-Messianic Jews (Ben Zakkai) was not accepted by the pro-Messianic Jews (Christians) nor by the Gentile converts to the Christian faith. Consider also, that the Masoretic Text, the authoritative Hebrew text of the Tanakh for Rabbinic Judaism, was was primarily copied, edited and distributed by a group of Jews known as the Masoretes between the 7th and 10th centuries AD.
In other words, what is now known as the 39-book Masoretic Text, pointed for vowels and all, did not reach its completed form until 700-1,000 years after after the beginning of the Christian Church.
If you want to abide by the Rabbinical Councils, and St. Jerome finally decided to abide by the Christian Councils, I would argue that Jerome made the better choice.
I’m at work now and cannot respond thoroughly. But, your remarks deserve a response. Yet, there is language in here which does not sound like you...
Before I waste a bunch of time here, I am curious about two things...
1. Is this really you writing this post?
2. If I rebut your (or the ghost writer’s) claims and demonstrate that the 66 books known as the Scriptures (without the Apocrypha) were in place long before there was such a thing as a “Roman Catholic Church” (which I assume are intended to support RCC authority to tell the world what is true), will you swim back over the Tiber?
