Q. Why does the Catholic Bible have seven more books than other Bibles?
A. Seven Old Testament books are found in Catholic Bibles but not in Protestant ones. Catholics call them the deuterocanonical (literally, “second canon”) books; Protestants call them the apocryphal (literally, “hidden,” thus “unknown, spurious”) books. These books include Baruch, Tobit, Judith, 1 and 2 Maccabees, Wisdom (or Wisdom of Solomon), and Sirach (or Ecclesiasticus).
They were included in the Septuagint, a third-century-B.C. Greek translation of the Old Testament, which served as the Scripture of the apostles and the generations that followed them. The earliest Greek manuscripts of the Old Testament, such as Codex Sinaiticus (fourth century) and Codex Alexandrinus (c. 450), include the deuterocanonical books with the others.
