There was no "closed" Catholic canon until AFTER the reformation ... At that time Rome added books that had previously not been in the canon for their own purposes..
The New Testament was finalized for Catholics and Eastern Orthodox in the Forth Century by St. Athanasios. Luther deleted the Epistle of James from the "Protestant canon" but Protestants quietly put it back a couple centuries later.
Where is “sola scripture” written in the Bible?
And I don’t mean with the words that Luther added to the Bible!!!!
The books Baruch, Tobit, Maccabees, Judith, Sirach, Wisdom and parts of Daniel and Esther were all included in the Septuagint that Jesus and the apostles used. Here are references from the Septuagint that appear in the Gospels. There are many more that appear in the Acts and the Epistles. I would say if those books were good enough for Jesus to reference, they are good enough for me.
