I personally take statement quoted by Jude from Enoch as true, but I don't think that necessarily means he automatically endorsed everything that was written in that book.
> Jude 14–15 (CSB): “Look! The Lord comes with tens of thousands of his holy ones to execute judgment on all and to convict all the ungodly concerning all the ungodly acts that they have done in an ungodly way, and concerning all the harsh things ungodly sinners have said against him.”
