I agree that only Christians should be debating the NT canon. That goes for today as well. We don't need the musings of non christian academics deciding what I believe to be foremost theological issue. However, The OT was pretty clearly understood by Jesus's time. The only lingering question was perhaps the inclusion of the Song of Solomon and Esther. This was issue discussed at the school of Jamnia according to Roger Beckwith. But also consider the words of Christ Himself in MATT 23:35:
Therefore, behold, bI am sending you prophets and wise men and scribes; some of them you will kill and crucify, and some of them you will cscourge in your synagogues, and dpersecute from city to city,
Matt. 23:35 so that upon you may fall the guilt of all the righteous blood shed on earth, from the blood of righteous aAbel to the blood of Zechariah, the bson of Berechiah, whom cyou murdered between the 1temple and the altar.
The events Jesus describes happen from the first book of the Jewish bible to the last book which is Genesis to 2 chronicles.
So He is saying from the beginning to the end of scripture. . . . . Perhaps He is limiting this to just the prophets. Yet I think there is a strong case Christ is giving us that canon. Something to think about.
