Yeah...infallability...here we go. The Vulgate was the source for proper canon. Let's get it right here.
The Vulgate confirmed by the Synods of Carthage in 397 and 418 weren't good enough of the church leaders....so over the years they just decided here and there to add one or two or three extra courses of material....But oh, that a reform movement upset with obvious church abuses and corruption had no right to strip those added non-inspired books from what was once only sacred, inspired scripture.
Sheesh...if your gonna try to present history at least paint a complete picture man!
In doing some follow-up research I note that Origen in 225 seems to expressly discount First and Second Maccabees as Holy Scripture and implicitly reject the remaining Apocryphal books.
Later, Augustine argues for and Jerome against counting the texts as scripture. I find Augustine's argument that the Septuagent (Greek translation of the old Hebrew Pentateuch) was more accurate than the Pentateuch very interesting. Augustine seems to also be the first church father that accepts what appears to be the lesser regarded Apocryphal books from the Pentateuch stand point....against the strong arguments of Jerome who was ordered by Pope Damasus I in 382 to include them in sacred scripture. Jerome was then tasked with producing the Vulgate including the Apocryphal books that everyone before Augustine (including Origen) had rejected as less than Holy books.
So we have books in the Canon that everyone agrees are God breathed, then we also include books that there was significant doubt about whether it was Holy or not.
I will need to find out what Jerome and Augustine's arguments were.
