“Trent only reaffirmed the Canon that had been established in 381 AD in response to the Reformation.”
You’re speaking of the First council of Constantinople? What canon, in respect to books of the Bible, did they establish? I’m going to need a link on this claim, because your Catholic Encyclopedia doesn’t even try to claim such a thing. The Vulgate hadn’t even begun to be translated yet at that time!
No, I am referring to the Council of Rome, called in 381 and concluded in 382. Pope Damasus did not attend the First Council of Constantinople making its standing dubious for another 70 years.
Peace be with you
