Simplified: The disputed books are often called the Biblical apocrypha , a term that is sometimes used specifically ( and possibly pejoratively in English ) to describe the books in the Catholic and Orthodox canons that are absent from the Jewish Masoretic Text ( also called the Tanakh or Miqra ) and most modern Protestant Bibles . Catholic Christians , following the Canon of Trent , describe these books as deuterocanonical , meaning of `` the second canon , '' while Greek Orthodox Christians , following the Synod of Jerusalem ( 1672 ) , use the traditional name of anagignoskomena , meaning `` that which is to be read .
