That sounds contradictory. First, they say that the book of Enoch is unreliable and full of myths. Then they say that because Jude was inspired that this one quotation from the book of Enoch is accurate. How stupid to reason that a book that is almost all fiction has one fact in it, therefore it can be quoted.
