I will not debate with you when you cited a work of a biased and anti catholic author.
I have only one question to prove/test the lie that you propagate.
If indeed there was no Septuagint Version of the OT before the birth of Jesus Christ, why are the Ethiopian Jews using the Siptuagint Version until now? These were the Jews who did not follow the insecure European Jews who composed the Council of Jamnia before 100 AD whose desire was only one, bring down christianity.
Furhtermore, you could not even say about the hypocracy of your cult when you followed luther who followed jamnia to denounce the 7 deuters but defied the same council when it denounced the NT which you retained. Hahahaha, Hypocrites.
Dont tell me that they adopted the LXX in 300 AD in exchange of the original hebrew that they had been using. for one source you can read this credible site: http://en.wikipedia.org/wiki/Septuagint
