Read what I have written again. You don't seem to have understood me and repeating myself is tedious.How does it ‘support’ a 39 book canon? Because we should trust the Jews regarding scripture? I certainly affirm that the 39 books of the Old Testament are the inspired word of God. I know why I believe that. Based on your answer, you seem to believe that the Bible is the word of God because some books of the canon refer to (an undefined list of) books as the word of God. This does nothing to help one understand which books are canonical.
But the Apocrypha cannot be the word of God, and its writers make no pretensions for it to be so. The phrase, 'Hear the word of the LORD' or similar which are common in the O.T. never appear in the Apocrypha. The writer of 1 Maccabees states three times that a prophet was no longer available in Israel (4:46; 9:27; 14:41). Then there are factual errors, especially in Judith and Tobit: for example, Judith 1:1 states that Nebuchadnezzar reigned in Nineveh instead of Babylon. The Prayer of Manasseh states that Abraham, Isaac and Jacob were not sinners.
As for the Church of Rome, 'pope' Innocent I included the Apocrypha in 405, at the very time that Jerome wanted to exclude it Another 'pope' excluded it around 600; 'Cardinal' Ximenes excluded it in the 16th Century only to be overruled by the Council of Trent. So any appeal to the 'Church fathers' fails.
