4. The Books Of The Apocrypha Were Written During The Silent Years
5. The Septuagint Translation Proves Nothing
The fact that the Apocrypha is found in the Septuagint translation does not prove anything.

12. The Apocrypha Is Not A Well-Defined Unit
13. The Councils At Hippo And Carthage Are Not Definitive
The fact that the councils of Hippo and Carthage accepted the canonical status of the Apocrypha is not decisive. First, they were not larger more representative councils. In addition, these councils had no qualified Hebrew scholar in attendance. Basically the Apocrypha was canonized at these councils because of the influence of one person - Saint Augustine.
There was one great Hebrew scholar among the Christian Church living in the era of Saint Augustine - Jerome the translator of the Latin Vulgate. Jerome rejected the Apocrypha as Holy Scripture in the strongest of terms. He refused to place it in his translation of the Old Testament. It was only after the death of Jerome that the Apocrypha was placed in the Vulgate - the official translation of the Roman Catholic Church. His expert testimony was rejected.
