You should read this only as a historical reference and not allow yourself to apply it as you do the inspired scriptures. I personally enjoyed reading this one and the Book of Jasher, but would never teach/preach anything out of either one.
There is credible evidence that Enoch had some very powerful revelations from God, but God chose not to allow the Book of Enoch to be put into the Bible. I also agree with your stance on Jude and Jude did quote directly from Enoch, but that does not make the Book of Enoch part of Holy cannon.
Take as historical and interesting, but don't ever confuse it with the truth of the Bible.
K here's the problem that I have with not putting the book of Enoch in the actual Bible...it's quoted in Scripture, it's been found with the Dead Sea Scrolls. And you say that God chose not to allow the book of Enoch to be put into the Bible, when in fact it was the Catholic Church that chose this (you know, the same church that we all broke away from, saying that many of the things they did/do was heretical.). Many of them didn't want to put the Book of Revelation in the Bible either, claiming that it was too dangerous of a text. It BARELY made it in the Bible.
So what happened? God inspired the Catholic Church to throw the Bible together and then quickly left them, turning their future actions into uninspired mistakes and booboos?
OR
Did the Catholic Church just make another booboo in their long historical list of booboos?
I haven't even read the entire book of Enoch, but from what I have read, it explains A LOT about how/why ancient civilizations knew about a lot of things that they could have never known otherwise without modern technology. It kicks the ancient aliens theories in the butt and gives a Biblical answer. Also, it follows the anti-gnosis (unless given by God) theme of the Old Testament.
Also, I have yet to read anything from the book that would incredibly change Christianity like trying to give new paths to redemption or any junk like that
