“The Orthodox believe they are the Catholic Church. I might add that they accept the same OT canon as the Catholic Church with the additions of the 3rd Book of Maccabees, the First Book of Esdras, and the Prayer of Manasseh. So what’s your point about the canon?”
Well, if the Orthodox have the same canon PLUS extra books, then the Orthodox do NOT have the same canon as the Roman Catholics.
Further, the Roman Catholic Church left unsettled at Trent if the Apocrypha was good for just reading, or if it was also good for determining doctrine. That remains an open question for Catholics.
That’s spurious. What happened at the Council of Trent was any debate over the canon was sealed and Tradition was reaffirmed.
My point is that the only people who dispute the canon of the Old Testament are the Protestants who preferred to listen to anti-Christian Jewish rabbis in selecting their canon rather than to the consensus of the early fathers and councils.
But Trent didn’t make any decisions on 3rd Maccabees, etc., so it is conceivable that they could be admitted as canonical by the Western Church at some point.
Referring to Judith, Maccabees, etc. was a Protestant innovation.
The Apostolic Constitutions c. 380 A.D., which constituted part of Roman Catholic canon law until 1917 and still do for the Orthodox:

Canon 85: Concerning Holy Scripture.
Let the following books be esteemed venerable and holy by all of you, both clergy and laity. Of the Old Testament: the five books of Moses, Genesis, Exodus, Leviticus, Numbers, and Deuteronomy; one of Joshua the son of Nun; one of the Judges; one of Ruth; four of the Kings; 1 two of Paralipomena (the books of Chronicles); two of Ezra; 2 one of Esther; [one of Judith;] 3 three of the Maccabees; one of Job; the one hundred and fifty Psalms; three books of Solomon: Proverbs, Ecclesiastes, Song of Songs; the sixteen of the Prophets. And see that those newly come to discipleship become acquainted with the Wisdom of the learned Sirach. 4 And ours, that is, of the New Testament, are the four Gospels, of Matthew, Mark, Luke, John; the fourteen epistles of Paul; two epistles of Peter; three of John; one of James; one of Jude; two epistles of Clement; and the Constitutions dedicated to you, the bishops, by me, Clement, in eight books, which it is not appropriate to make public before all, because of the mysteries contained in them; and the Acts of us, the Apostles.
