WHY THE BOOK OF ENOCH IS NOT INSPIRED?

In 1956, during the excavation of the Dead Sea Scrolls, a book called "1 Enoch" (a.k.a. The Book of Enoch) was discovered. (NOTE: The excavation uncovered a variety of texts, many of which were not Scriptural.)

Enoch 1:9 says this:
And behold! He cometh with ten thousands of holy ones to execute judgement upon all, and to destroy [all] the ungodly: and to convict all flesh of all the works [of their ungodliness] which they have ungodly committed, and of all the hard things which ungodly sinners [have spoken] against Him.
Clearly this is very similar to Jude 1:14-15.
•    Was Jude quoting The Book of Enoch?

NO! Consider what Jude 1:14-15 says in the NASB - God's Word says that there will be a judgment executed upon all. But there is no stipulation that they will all be destroyed at that time:

Jude 1:14-15 (NASB)
14  "It was also about these men that Enoch, in the seventh generation from Adam, prophesied, saying, "Behold, the Lord came with many thousands of His holy ones,
15  to execute judgment upon all, and to convict all the ungodly of all their ungodly deeds which they have done in an ungodly way, and of all the harsh things which ungodly sinners have spoken against Him."

•    If so, does this mean the Book of Enoch should be considered Scripture?
•    Were The Book of Enoch and Jude both quoting from an earlier text (i.e. the actual account of Enoch)?
•    Was the author of The Book of Enoch actually quoting from Jude to make their book look more credible?
What we don't know is when The Book of Enoch was written, who the author was, or what Jude was quoting. :)

The best one can tell, the Biblical figure Enoch was not the author, but rather, someone who lived closer to the time of Christ, or possibly even after, based on some of the references. There are many arguments on all sides of this debate, but the real question in the back of many Christian minds is:
Is it Scripture?
Is this the Holy-Spirit inspired word of God? This is where we can pretty confidently say "no". If it were Scripture, we would expect it to be free of false doctrine. What we find instead is that false doctrine is one of the most prevalent themes in the book!
Taking a cursory look at the text up through Chapter 59, are found the following false doctrines.
•    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.

notes from www.refuteit.com/the-book-of-enoch-debunked.html below

Jude never said he was quoting from the book of Enoch.
Jude: to convince all that are ungodly.
Enoch: to destroy all that are ungodly.
Jn 16:8: to convict the world about sin - nothing mentioned about destroying all the ungodly, especially since all men but Christ are ungodly.

Ac 17:8; Titus 1:12: Paul quotes from pagan sources in order to convince pagans of the gospel. But that does not make these sources Scripture.

Enoch 5:6 - in end times - those living in Tribulation times: sinners find no mercy, no salvation
Rev 14:6: I saw an angel flying in mid heaven, having an eternal Gospel to proclaim...
cp 2 Pet 3:9, Rev 7:14; 9:20, 16:9; 20:4

Enoch 7:2 450 foot giants and 4,500 foot giants
Dt 3:11 Kg Og largest 9 cubits ~13 feet

Enoch 10:8 - sin entered the world through a fallen angel named Azazel.
Ro 5:12 - sin entered the world through one man [Adam]

Enoch 10:20-21 - Michael the Archangel was to cleanse the world from sin - before the flood.
Gen 6:5 states that men even after the flood were sinful. So there was no cleansing of sin by the angels.
Dan 9:24 - Yeshua would put an end to sin
Acts 4:12; 1 Tim 2:5; Col 1:19-22 - salvation only through Christ

Enoch 19:2 - women will become mythical like creatures
 The siren was a pagan, mythical creature that took for the form of a half woman and half bird that lured sailors into danger with their singing. It was believed that they were cannibals.

The Bible has no such passage. Species do not evolve into other species, they create after their own kind.

Enoch 39:1 - people will descend from heaven and their children will become one with the children of men.

This passage implies that the elect and holy children will come down from heaven in the last days with their 'seed' (children) and the children will become one with the children of men.

The Bible does not support this.

Enoch 41:1 - the kingdom of God is divided.
Mt 12:25 - If a kingdom is divided it cannot stand.
Dan 2:44 - God's Kingdom will never be destroyed.

Enoch 41:2 - Sinners will be evicted from the Mansions in Heaven.
Jn 14:2 - the mansions were built in heaven for the saved, not sinners

Enoch 46:1-3; 48:1-3, 6 - Jesus the Son of Man was created, therefore not God
Enoch 71:14 - Noah was taken up to heave like his grandfather (Enoch) "he translated my spirit into the heaven of heavens" (71:5) and Noah said he saw the "Son of Man." Noah sujpposedly writes, "This is the Son of Man who is born unto righteousness of the Head of Days forsakes him not." - again it claims Jesus was born (created) in heaven before he came to earth in the form of a man. Not scriptural.

The Book of Enoch claims Noah was translated to heaven prior to the flood and this "Son of Man" figure was already born and seated on a throne. The Sonof Man also participated in the judgment of the flood as seen in Enoch 69:26-28. Strangely, the Book of Enoch also calls Noah the "son of man" in Enoch 60:10. However, all of this is contradictory to the scriptural account.

The wording in the above posted portions gives the impression that Jesus is nothing more than a man who was selected before the earth was created -- This is all incorrect. Jesus is God and not a creature of God.
The bible clearly teaches that Jesus was not just a man, nor was He an angelm, and He was not a special creation. Jesus always existed with the Father, becaue Jesus, with the Father, and the Holy Spirit are God.
Compare Jn 1:1-3, 14; Titus 2:13-14.

Enoch 47:4 - God requires righteous blood offerings.
God requires the shedding of human blood for a sacrifice. So Christ's blood was insufficient.
Heb 10:10, 12, 14, 26 - Christ's offering is final, not other is required.
Compare 1 Pet 3:18
