Jude considered the book of Enoch inspired and that is why he quoted a prophecy from this book.
Lovelylil,
Sure Enoch prophesied and so did a lot of others. Sometimes they were right and sometimes they were wrong. This does not mean that they did not prophesy. Jude, like James his brother was writing to Jews that once supported the Law while also Christians to make the point that this Law was no longer valid for salvation. And such Jews would have read the book of Enoch because it was also included with their scrolls in their temples but kept separated. That is why Jude could quote from it. It would still have been considered sacred to them but not inspired. And to who did Jude apply such words? To such Jews of course to whom he was writing like this: 15 To execute judgment upon all, and to convince all that are ungodly among them of all their ungodly deeds which they have ungodly committed, and of all their hard speeches which ungodly sinners have spoken against him. 16 These are murmurers, complainers, walking after their own lusts; and their mouth speaketh great swelling words, having men’s persons in admiration because of advantage. It was not to their benefit that he did this. Bur to other Jews also reading this letter not keeping the Law or under such condemnation Jude said: 17 But, beloved, remember ye the words which were spoken before of the apostles of our Lord Jesus Christ; Not Enoch's words but who's? The words of the apostles of our Lord Jesus Christ. Not the same picture you are painting is it Lovelylil, and he made his point to them in a forceful way.
