In Jamnia c 90, according to one theory now largely discredited, rabbis endorsed a narrower canon, excluding deuterocanonical works such as 2 Maccabees. This had little immediate impact on Christians, however, since most Christians did not know Hebrew and were familiar with the Hebrew Bible through the Greek Septuagint text from hellenistic Jews, although some researchers believe that under Christian auspices the books known to Protestants and Jews as apocryphal and to Roman Catholics as deuterocanonical were added to the Septuagint. In addition, the canonical status of deuterocanonical books was disputed among some notable scholars from early on and into the Council of Trent, which first definitively settled the matter of the OT Canon on 8 April 1546, after the death of Martin Luther.
