The Formation Of The Canon: The Old Testament

"The Hebrew Scriptures were recognized as authoritative at their inception, and were immediately accepted as such by the Jewish people. The acceptance of the Pentateuch, for example, is recorded in Deuteronomy 32:46-47, and in Joshua 1:7,8. As a matter of course, the Church of the first century regarded the Hebrew Scriptures as inspired. Jesus, in Luke 24:44, refers to the Law, the prophets, and the psalms (or the writings) as divinely authoritative and canonical. The Jews accepted all of the 39 books of the Old Testament as inspired. A confirmation of public opinion along these lines was made at the synod at Jamnia." Also mentions briefly about Philo, Josephus, and Origen.
