What, give names of Orthodox Jewish academics?
Haha, no my friend I was just joking with you. Of course I believe they exist!
like ben-Sira, Judith, Tobias, Maccabees
Fascinating works.
I highly recommend you check out 2 Esdras though. Not just for the allusions of Messiah but also because of the detail of how Scripture came to be after the Yahudah's return from Babylon - including the formation of an early canon.
other books were dismissed, such as Judith, Susanna
As I understand it, Susanna may have been deliberately left out due to the controversial depiction of the leaders in the book. It didn't paint them a great light at all, and so may have been "edited" out along with other books that didn't harmonise with the Pharisaic standpoint. This is a slippery slope. Removing a second book will be twice as easy as removing the first. Unfortunately, this is still happening today.
We may therefore assume that it was obvious to the sages that works such as the Testament and Enoch were post-prophetic works
One could assume that, but should they?
Which do you think is wiser? Assessing a book for yourself, using your acute powers of analysis, or assuming someone else has done so adequately before? If we assume real infallible geniuses have gone before us, then what new ground can we ever hope to break? With that assumption, over time wouldn't we slowly and consistently become reductive in our own opinions and experiences?
I remember seeing an explanation for this, but can't quite remember. Possibly because it contradicts way too many Jewish traditions. Another possibility is that it was concluded, as mentioned above, to not have been from the era of prophecy.
It's another one worth checking out. Even if it's as approached as a fiction novel.
