  4. Sirach (Ecclesiasticus)

Why Are There Differences in the Number of Books?

The differences in the number of books in the Bible stem from historical debates about which texts should be considered Scripture.

  1. Jewish Canon:
    Jewish religious leaders finalised the Hebrew Bible (Tanakh) around the 1st century CE, excluding texts found in the Septuagint.
  2. Christian Canon:
    Early Christians used the Septuagint, which included additional books. However, during the Reformation, Protestant leaders chose to exclude these Deuterocanonical books, considering them non-canonical.
  3. Catholic and Orthodox Views:
    The Catholic Church reaffirmed the inclusion of the Deuterocanonical books at the Council of Trent in the 16th century. The Orthodox Church retained even more texts based on long-standing tradition.
