The Protestant OT vs
the Catholic/Orthodox OT:
Why do they have different books?


The short answer: The last book in the Protestant OT is technically the same last book in the Catholic and Orthodox OT’s: Malachi. But Catholic and Orthodox Bibles have additional books in between the OT and NT. But why? Malachi lived around the year 450 BC. That means that there was a gap of 450 years between the OT and NT. Since Malachi was a prophet, that means that he was the last OT prophet, and his book is the last book in the Protestant OT. No other prophet lived until John the Baptist. Protestant theologians since the time of Martin Luther (1500s) have taught that only books that came from prophets should be in the OT.

But Catholics and Orthodox decided long ago to include books written during that 450-year gap period. Some of the books were supposedly written at the same time as the last of the OT books, but most of the “extra” books were written later. Also, Catholics and Orthodox do not believe that those extra books are not on the same spiritual level as the other 39 OT books. To show that, a special name was given to the extra books: Deuterocanonical. This word sounds intimidating, but not once you break it in two: “deutero” means “secondary” and “canonical” (in this word) means “Scripture. So, deuterocanonicals are “secondary Scripture.” Although Catholics and Orthodox include “extra” books in their Bibles in between the OT and NT, they use this word to show that those books are not on the same “spiritual” level as the 39 OT books, but still should be read.

On the other hand, Protestant scholars rejected the deuterocanonicals and instead refer to them as “Apocrypha,” meaning that they contain false teachings or heresies. But that is why there are no “extra” books in the Protestant OT: the general feeling is that only those books that are truly from God and on a certain spiritual level (such as all the OT and NT books are) get to be in the Bible. No matter how popular a book was, and some books were very popular, Protestants believed that no book should be in the Bible unless it was from God; Catholics and Orthodox believed differently.

Note: Protestant, Catholics, and Orthodox all use the same 27 NT books.
