Your own St. Jerome and St. Augustine, for starters.
This would be the same Jerome that translated the Bible into Latin from the original Greek and Hebrew, the same Jerome that even though he was not certain bowed to the wisdom of those that came before him.
Would it be this same Augustine that refuted Mani with this quote: "If you should find someone who does not yet believe in the gospel, what would you [Mani] answer him when he says, I do not believe? Indeed, I would not believe in the gospel myself if the authority of the Catholic Church did not move me to do so"
The same Augustine that quoted extensively form those same "disputed" books in his sermons and refutations of heretics?
The truth is protestants are trying to hand their hat on the same nail as the very people that rejected the entire New Testament. Do you really want to use the OT only?
And of course the ever popular: "Roma locuta est, causa finita est." -St Augustine Roughly translated: Rome has spoken, it is settled.
