Sorry. According to my historical references the deuterocanonical books were not considered inspired scripture by the Hebrew fathers at the time of Christ. If you could point me to some sources that would say otherwise I'd be happy to review the material.
As I stated before, I'm really not interested in what the Sadducees believed because they were way off base as our Lord told them. He considered the Pharisees to be knowledgable in the scriptures but legalistic in practice.
At the time of Christ, everyone knew what our Lord Christ meant when He stated, "You search the scriptures...", "What does the scriptures say...", "The scriptures states...". People didn't run around saying, "Gosh, does He mean the Sadducees' version or the Pharisee's version?
The Septuagint was a Jewish Bible used by the hellenized Jews for two hundred years before Chirst and at the time when the Apostles wrote the NT, and it contained the books that the Pharisaical bible did not.
It is important because the Apostles quote from the Septuagint and not from the "Hebrew" Bible in over 93% of the cases. You figure out the rest.
I couldn't care less what the Sadducees believed either. I used them to show you that there was no such tinng as one Judaism or that the "Hebrew" Bible was one and the same book you read today in your Old Testament.
