I think we must include the book of Enoch in the Catholic Bible (as well as other books). The book of Enoch is quoted by Jude and 2 Peter. However, Jehovah's Witnesses follow the Protestant's canon. Note how they argue against the Apocrypha in the Insight Book vol. 1 (it-1 pp. 120-125):
The internal evidence of these Apocryphal writings weighs even more heavily against their canonicity than does the external. They are completely lacking in the prophetic element.
Ohhh, really?, Was not the book of Enoch prophetic? What about the false prophecies of Ezekiel against Tyre and Egypt ?
Their contents and teachings at times contradict those of the canonical books and are also contradictory within themselves. They are rife with historical and geographic inaccuracies and anachronisms.
Ohh, really?....What about the geographic inaccuracies in Mark?, What about the many contradictions found in the entire canonical books of the Bible? see some of them here : http://www.answering-christianity.com/101_bible_contradictions.htm
The writers in some cases are guilty of dishonesty in falsely representing their works as those of earlier inspired writers.
OOOhhh, was the writer of the book of Daniel honest with his identity? How could he tell us that the son of Nabuchadnezzar was Belshazzar? The Jewish Encyclopedia says: "Nor would a contemporary of Nebuchadnezzar and his successors have written the stories of the Book of Daniel in the form in which they exist, since they contain many details that can not be harmonized with the data furnished in other historical sources."
The Watchtower shows its great ignorance.
