Why Do Protestants and Catholics Have Different Bibles?
During the 16th century Protestant Reformation, reformers including Martin Luther returned to the Hebrew canon (Tanakh) as the standard for the Old Testament. The Hebrew Bible did not include the deuterocanonical books, which were written in the Intertestamental period and found in the Greek Septuagint (the translation used by the early church).
Catholics point out that the early church used the Septuagint and that these books were considered Scripture by many church fathers. The Council of Trent (1546) formally defined the Catholic canon in response to the Protestant challenge.
The Ethiopian Orthodox Canon: 81 Books
The Ethiopian Orthodox Tewahedo Church has the broadest canon of any Christian tradition — 81 books, including texts not recognized elsewhere such as 1 Enoch and Jubilees. Ethiopian Christianity is one of the oldest in the world, dating to the 4th century, and developed its canon somewhat independently of Western Christianity.
