Very little for either one, if the truth be told. People being actively persecuted usually don't have much time for theological debates.
Jerome was also dead set against including the "deuterocanonical" books in the Bible.
Not "dead set" at all. When it became clear he was on one side and Rome was on the other, he obeyed the Pope like the good son of the Church he was.
I guess someone forgot to tell this to Jerome. In his Preface to "Proverbs, Ecclesiastes, and the Song of Songs," he wrote:
"As, then, the Church reads Judith, Tobit, and the books of Maccabees, but does not admit them among the canonical Scriptures, so let it read these two volumes for the edification of the people, not to give authority to doctrines of the Church. "Jerome plainly set aside the so-called "deuterocanonical" books apart from the rest of the Vulgate and it remained that way in most editions. This fact was understood up until the time of the Council of Trent. Indeed, the famous Cardinal Cajetan, in his "Commentary on all the Authentic Historical Books of the Old Testament," wrote:
"Here we close our commentaries on the historical books of the Old Testament. For the rest (that is, Judith, Tobit, and the books of Maccabees) are counted by St. Jerome out of the canonical books, and are placed amongst the Apocrypha, along with Wisdom and Ecciesiasticus, as is plain from the Protogus Galeatus.Remember, if you accept the "deuterocanonical" books as Scripture, you have to believe the following passage:
"If the Devil, or an evil spirit troubles anyone, they can be driven away by making a smoke of the heart, liver, and gall of a fish...and the Devil will smell it, and flee away, and never come again anymore." (Tobit 6:5-8)I stand on the side of Jerome, Athanasiusm, Origen, Epiphanius, Basil the Great, Melito, Gregory of Nazianzen, Hilary of Poitiers, and many others in rejecting these kinds of superstitions.
Yeah, funny what people will do to avoid being killed.
