I have no clue how to find what books were actually used in the temple then ...all we have now is the offical cannon of the Jews..which was set after Jesus I believe
We do know that other books were referenced in the Epistles (like Jude)..once quoted in scripture I take that quotes inspired but not necesarily the entire text..
The Hebrew scriptural canon was sealed at the end of the Babylonian Exile by the Anshei Knesset Hagedolah (Great Synod), around 450 B.C.
I have many friends ... smart and dumb, Catholic and Protestant and Jewish, ... we can agree to disagree as long as we respect each other as children of God.
Besides, I haven't lost hope for you ... many "ex Catholics" come back to the church!
God bless.
