It is an interesting book. It isn't recognized as a canonized book of the Bible by Protestants.
There is a part of the book of Enoch that appears to be quoted in Jude.
However, the book of Enoch contradicts the Bible in at least 30 places.
Taking a cursory look at the text up through Chapter 59, The following false doctrines. (I may be off on one here or there, but it should be sufficient to get my point across.)
1:1 Implies restoration during tribulation - not congruent with scriptures.
1:8 In conflict with the doctrine that peace was made at the cross. Also, in the last days tribulation will increase for the righteous - this "verse" seems to dispute that.
2:2-3 Appears to contradict 2 Pet 3:3-7
5:4 Is an admonition to some unknown party - this is very irregular relative to the scriptures (i.e. authentic ancient writings by God-fearing Jews)
6:3 Semjaza seems to be listed as the leader of the angels, which is not scriptural
6:3,8 None of these angels are mentioned in the Bible
8:1 Azazel isn't even listed in 6:8 as one of the angels that fornicated with women
8:3 Araqiel and Shamsiel aren't listed in 6:8 either
10:2 Enoch allegedly wrote about Noah, even though the Bible teaches that Enoch was taken up to heaven years before Noah was born.
10:4-6,12 Implies angels can be bound & hid in holes under rocks. This is contrary to scripture.
10:8 Ascribes all the sin of the fallen angels to one named Azazel - not scriptural.
10:15-11:2 Seems to imply that permanent restoration took place after the flood - clearly not true. It seems the true author of this book confused scriptures pertaining to the future restoration.
13:5-6,14:4-5,7 Implies fallen angels can't talk to God - this contradicts Job. Also implies that angels were repentant, but weren't received back by God - very strange doctrine.
14 Gives a very strange description of Heaven that conflicts with many scriptures
15:8-10 Very strange doctrine about "evil spirits" proceeding from unredeemable giants
17-18,21,23 Gives a very strange description of the earth & universe which is clearly not true. Also alludes to the ancient model of astronomy that held that there were 7 stars (the closest planets) which burned like the sun (they don't.)
19:3 Discredits all other prophecy about the consumation of the ages.
20 Lists strange angels not in scripture, and incorrectly assigns the roles of Michael (the warrior) and Gabriel (the messenger)
21:7-10 Seems to contradict Biblical descriptions of the present & final judgement places for the fallen angels
22 Contradicts the Biblical descriptions of past, present & future dwelling places for the righteous who die
32:2-6 Seems to imply the Garden of Eden was still in existance after the Flood
33:1-2 Says Heaven rests on a foundation that is at the Eastern edge of the earth
33:3 He claims he counted the stars & individually mapped them, which is impossible scripturally (& scientifically)
34 Says the winds come out of a "portal" at the Northern edge of the earth
36:3 Says the stars come out of portals at the Eastern edge of the earth & move West
38:5-6 Contradicts Daniel & other prophecies about the Mellinial Reign
39:1-2 Very strange implications here about the "seed" of angels dwelling with men at the end... this contradicts the scriptures
40:7 Talks about the "Satans" - plural, different than the Bible, who gives that name to only one fallen angel. Also, implies Satan can't stand in God's presence, contrary to Job.
40:9 Once again mixes up the roles of the 2 Archangels & adds more names in. Michael's role in scripture is related to conquoring nations & fighting spiritual wars, while Gabriel's relates to bringing messages & visions to people.
41:1-2 Says the Kingdom of God is divided - it's not & can't be scripturally. Also describes sinners being repelled from a mansion, which is also not scriptural, unless you look at a parable Jesus told, which was not intended to be literal.
41:4-5 Says the sun, moon, winds, etc. are stored in chambers & released at appointed times.
41:6-7 Implies the sun & moon move opposite of each other
43:1-3,44 Very weird model of the nature of stars & lightning
47:4 Says God requires the blood of the saints... very strange
51:1 Says Sheol & Hell will give back to the earth, which isn't scriptural - also Hell is a NT term, not OT
51:2 Disputes the Biblical doctrine that we are chosen. (We don't have to wait until Christ's return to be chosen.) This isn't scriptural.
General: Seems to imply Enoch came back down to earth after being taken up to Heaven, which is not scriptural.
Also, the book of Enoch mentions things that happened long after Gen 5:24;
So there is no way Enoch could have written it.
