What Protestants call "the Apocrypha" is what Catholics call "the Deuterocanon".
What
Catholics call "apocrypha" is what Protestants call "pseudepigrapha".
Anyone ever hear of the Book of Jasher?
I believe it was referred to in the KJV.
"Is not this written in the Book of Jasher?"--Joshua, x. 13.
"Behold it is written in the Book of Jasher."--II Samuel, i. 18
And not only the Book of Jasher, but a whole boatload of Scriptural books are mentioned in Scripture that we just plain don't have any more. What we know as the Old Testament is only a
part of the writings produced by the ancient Jewish people. For example:
The Acts of Solomon (see 1 Kings 11:41)
The Book of the Wars of the Lord (Numbers 21:14)
The Book of Nathan the Prophet (1 Chronicles 29:29)
The Book of Gad the Seer (1 Chronicles 29:29)
The Prophecy of Ahijah the Shilonite (2 Chronicles 9:29)
The Visions of Iddo the Seer (2 Chronicles 9:29)
The Book of Shemaiah the Prophet (2 Chronocles 12:15)
The Story of the Prophet Iddo (2 Chronicles 13:22)
The Chronicle of Jehu, Son of Hanani (2 Chronicles 20:34).
Who knows what these books might have contained??? We'll never find out, since all of them were destroyed or lost over the long course of Israelite history.
Is the Bible incomplete without them? Maybe. But then, the Jewish folks have their rabbinic schools and the Talmud to "fill in the gaps" left in the Bible, and the Catholics have Sacred Tradition and the Magesterium of the Church to do the same. The Protestants believe the Bible to be sufficient unto itself, so if there are troublesome passages or apparent gaps, then they live with them.
