Cyril and Jerome were in Jerusalem they say the Jews had fixed Cannon.<quoted text>
The Essenes had Tobit and Sirach in their collection, what do you mean it doesn't mitigate against your belief? Protestants argue that there was an established Jewish canon of scripture around the time of Jesus, but there wasn't. It didn't happen in Judaism until 90 AD. The men who tried and executed the Lord, established the Protestant canon of scripture. This doesn't pose a problem for you?
So they found Essense had Sirach in a clay pot in the same cave as Isaiah, if you go to my house I have the book Lonely planet Brazil on the same bookshelf as my Bible does that make them both scripture?
If we think illogically and stupidly like you the answer is yes.
