Regarding Jerome - you consider that authoritative? One person is to overthrow the entire rest of the Church's mind on this subject? Of course Jerome was biased towards the Hebrew Scriptures - it was he who was tasked with interpreting it. Naturally, he would feel that his work was more important than those looking to the Septuagint.
I have already explained Athanasius, and can provide similar quotes for Hilary and for Cyril. They use them when making theological statements, using the Word of God and interpreting it. If they consider Isaiah and Wisdom as equal and without distinction when making a theological statement, it would appear that these saints considered the writings in question as inspired by God, although NOT part of the canon. Remember, canon referred to the writings that were read during the Mass, not writings that were considered inspired by God. That is a relatively new definition.
There are more. Some accepting of the Apocryphal books, some not, some with mixture. But this should suffice to answer your assertion that "Jerome was the ONLY one."
As I said, you are assuming you know what I have found. I disagree with your presumptions, and continue to say that I have found ONLY Jerome as a Catholic saint of the era who was strongly against the idea of including the OT Deuterocanonicals into the Canon that was being formed at the turn of the 5th century... What you ALSO forget is that Jerome, unlike Luther, accepted the decision of the Church, understanding that GOD guides the Church as a whole, not as individual disembodied folks who have thousands of different opinions on an assundry of topics...

Don't give them ideas Jo! Next thing we will see will be someone posting an 'authoritative' Protestant article claiming that, since the Eastern Orthodox Church never reads from the book of Revelation, it must not be part of the EO canon!
