Please be aware that it was not "Rome" that changed the Old Testament Canon, but the Jews. In the first century there was not just one "Jewish Canon", but at least four. There was the Sadducetic canon which taught that only the Torah, the first five Books, were Scripture, the Pharisaic, the one used in the Protestant Bible, that taught that the entire Hebrew Tanakh was Scripture, the Essene canon and the Hellenistic canon, used my the vast majority of first century Jews, forms the basis of the Catholic canon. There is some evidence that each of the many qahals had a particular derivative canon.
Peace be with you.

I see. So when Protestants don’t keep up with the canon pronounced at Trent, we are accusing of “changing” the canon, but when Rome doesn’t keep up with the most recent canon pronounced by the Jewish authorities, that is “okey-dokey”.
