This was never a topic we discussed growing up as a Protestant. In school, I heard and read about the various reasons why we don’t include what we call the Apocryphal books. Below is partly what I remember, partly what I found in a quick look on-line. Its not meant to be inclusive or even what I personally believe, but I think it is representative of various Protestant views I’ve ran into.
The Luther Bible included what Protestants call the Apocrypha, labeling them: "APOCRYPHA, that is, Books which are not to be esteemed like the Holy Scriptures, and yet which are useful and good to read”. Calvin wrote, “I am not one of those, however, who would entirely disapprove the reading of those books”.
Edward F. Hills wrote in The King James Version Defended:
But although all Protestants rejected the Apocrypha as canonical Old Testament Scripture, there was still considerable disagreement among them as to what to do with these controversial books. Luther rejected 1 and 2 Esdras, and placed the other apocryphal books in an appendix at the close of the Old Testament … The early English Bibles, including finally the King James Version, placed the Apocrypha in the same location, and in addition the Church of England retained the custom of reading from the Apocrypha in its public worship services during certain seasons of the year. In opposition to this practice Puritans and Presbyterians agitated for the complete removal of the Apocrypha from the Bible. In 1825 the British and Foreign Bible Society agreed to this, and since this time the Apocrypha has been eliminated almost entirely from English Bibles (except pulpit Bibles).
Examples of Protestant Bibles that included the Apocrypha: Tyndale’s Bible (1525 A.D.), Coverdale’s Bible (1535 A.D.), Matthew’s Bible (1537 A.D.), Taverner’s Bible (1539 A.D.), the Great Bible, (1539 A.D.), the Geneva Bible (1560 A.D.) and the Bishop’s Bible (1568 A.D.).
Another reason sometimes cited is that these books were not formally added to the Canon of the Catholic Church until the Council of Trent:
*And it has thought it meet that a list of the sacred books be inserted in this decree, lest a doubt may arise in any one’s mind, which are the books that are received by this Synod. They are as set down here below:
Of the Old Testament: the five books of Moses, to wit, Genesis, Exodus, Leviticus, Numbers, Deuteronomy; Josue, Judges, Ruth, four books of Kings, two of Paralipomenon, the first book of Esdras, and the second which is entitled Nehemias; Tobias, Judith, Esther, Job, the Davidical Psalter, consisting of a hundred and fifty psalms; the Proverbs, Ecclesiastes, the Canticle of Canticles, Wisdom, Ecclesiasticus, Isaias, Jeremias, with Baruch; Ezechiel, Daniel; the twelve minor prophets, to wit, Osee, Joel, Amos, Abdias, Jonas, Micheas, Nahum, Habacuc, Sophonias, Aggaeus, Zacharias, Malachias; two books of the Machabees, the first and the second.*
Some of the other reasons cited:
• They are not, and have never been, in the Jewish canon.
• Josephus explicitly excluded them from his list.
• Philo (20 B.C.-50 A.D.) neither mentions or quotes them.
• They were never quoted or alluded to by Jesus Christ or any of the apostles. The sermons in the Book of Acts, which outline Jewish history, do not included apocryphal events.
• Jewish scholars meeting at the Council of Jabneh did not recognize them.
• None of the Apocrypha claim inspiration or divine authority.
