[font="Arial, Helvetica"]At the time the Christian Bible was being formed, a Greek translation of Jewish Scripture, the [/font][font="Arial, Helvetica"]Septuagint[/font][font="Arial, Helvetica"], was in common use and Christians adopted it as the Old Testament of the Christian Bible. However, around 100 A.D., Jewish rabbis revised their Scripture and established an official canon of Judaism which excluded some portions of the Greek Septuagint. The material excluded was a group of 15 late Jewish books, written during the period 170 B.C. to 70 A.D., that were not found in Hebrew versions of the Jewish Scripture. Christians did not follow the revisions of Judaism and continued to use the text of the Septuagint.[/font]
[font="Arial, Helvetica"]Protestant reformers in the 1500s decided to follow the official canon of Judaism for the Old Testament rather than the Septuagint, and the excluded material was placed in a separate section of the Bible called the [/font][font="Arial, Helvetica"]Apocrypha[/font][font="Arial, Helvetica"]. Protestant Bibles included the Apocrypha until the mid 1800s, but it was eventually dropped from most Protestant editions.[/font]
[font="Arial, Helvetica"]The Roman Catholic and Orthodox Churchs continue to base their Old Testament on the Septuagint. The result is that these versions of the the Bible have more Old Testament books than Protestant versions. Catholic Old Testaments include [/font][font="Arial, Helvetica"]1st[/font][font="Arial, Helvetica"] and [/font][font="Arial, Helvetica"]2nd[/font][font="Arial, Helvetica"] [/font][font="Arial, Helvetica"]Maccabees[/font][font="Arial, Helvetica"], [/font][font="Arial, Helvetica"]Baruch[/font][font="Arial, Helvetica"], [/font][font="Arial, Helvetica"]Tobit[/font][font="Arial, Helvetica"], [/font][font="Arial, Helvetica"]Judith[/font][font="Arial, Helvetica"], [/font][font="Arial, Helvetica"]The Wisdom of Solomon[/font][font="Arial, Helvetica"], [/font][font="Arial, Helvetica"]Sirach[/font][font="Arial, Helvetica"] (Ecclesiasticus), additions to Esther, and [/font][font="Arial, Helvetica"]Susanna[/font][font="Arial, Helvetica"] and [/font][font="Arial, Helvetica"]Bel and the Dragon[/font][font="Arial, Helvetica"] which are included in Daniel. Orthodox Old Testaments include these plus [/font][font="Arial, Helvetica"]1st[/font][font="Arial, Helvetica"] and [/font][font="Arial, Helvetica"]2nd Esdras[/font][font="Arial, Helvetica"], [/font][font="Arial, Helvetica"]Prayer of Manasseh[/font][font="Arial, Helvetica"], [/font][font="Arial, Helvetica"]Psalm 151[/font][font="Arial, Helvetica"] and [/font][font="Arial, Helvetica"]3rd Maccabees[/font][font="Arial, Helvetica"].[/font]
