Hey Rightlydivide, did you read this article?
the arguements are not only weak but inaccuate… "In his later years St. Jerome did indeed accept the Deuterocanonical books of the Bible. In fact, he wound up strenuously defending their status as inspired Scripture, writing, “What sin have I committed if I followed the judgment of the churches? But he who brings charges against me for relating the objections that the Hebrews are wont to raise against the story of Susanna, the Son of the Three Children, and the story of Bel and the Dragon, which are not found in the Hebrew volume (ie. canon), proves that he is just a foolish sycophant. For I wasn’t relating my own personal views, but rather the remarks that they [the Jews] are wont to make against us” (Against Rufinus 11:33 [A.D. 402]). In earlier correspondence with Pope Damasus, Jerome did not call the deuterocanonical books unscriptural, he simply said that Jews he knew did not regard them as canonical. But for himself, he acknowledged the authority of the Church in defining the canon. When Pope Damasus and the Councils of Carthage and Hippo included the deuterocanon in Scripture, that was good enough for St. Jerome. He “followed the judgment of the churches.”
Shea not only claims that Jerome accepted them, but that he “strenuously” defended them. A word used to intrigue the reader, but there is no evidence that he defended them, let alone “strenuously.” Furthermore, from the citation above, he states that Jerome followed the “judgment of the churches”, which Shea translates as the synods of Hippo and Carthage, but he is mistaken. Contextually, the “judgment of the churches” refers to Theodotion’s translation of Daniel which the churches were using instead of the Septuagint version. To add to this, he couldn’t have followed Carthage considering they met 17 years after Jerome penned the above. Both Hippo and Carthage were regional councils, didn’t speak for the entire church, thus it wasn’t mandated that Jerome submit to their decisions. Yet, it was Theodotion’s version Jerome refers to when he mentions the “judgment of the churches” and not their decision on canon:"
the problem with this is there was more than one council of carthage and the council that was about the cannon was in 397
