John, "the disciple whom Jesus loved," also implicitly endorsed Enoch as a Prophet, because some of John's apocalyptic visions in the book of Revelation mirror those in Enoch.  Below are some close parallels between Enoch and Revelation.  The first describes the Great Tribulation, the second describes the Final Judgment, and the third describes the Regeneration: 

 

Enoch 100:3-4 – The horse will wade through the blood of sinners, and it will come up to their chest.  The chariots will be completely submerged [in blood].

compare with

Revelation 14:20 – Blood came out of the winepress and came up to the horse’s bridles for a distance of sixteen hundred stadiums.

 

Enoch 81:2 – I read the tablet that recorded all the works of everyone born of human flesh, everyone who lived on the face of the earth throughout all ages. 

Enoch 51:1 – The grave will give back everything it has received, and hell will pay back all of its debts.

Enoch 108:3 – (The transgressors') names will be blotted out of the Book of Life.

compare with

Revelation 20:12-15 – Books were opened.  And another book was opened, the Book of Life.  And the dead were judged by what things are recorded in the books, according to their works.  And the sea gave up the dead that were in it, and death and hell gave up the dead that were in them… and anyone who was not written in the Book of Life was thrown into the lake of fire.

 

Enoch 91:16-17 – The first heaven will pass away, and a new heaven will appear, which will shine seven times more billiant forever.

compare with

Revelation 21:1 – And I saw a new heaven and a new earth, for the first heaven and the first earth had passed away.

    

     Considering the fact that Revelation draws its metaphors from Old Testament books – from Daniel, Ezekiel, Zechariah, and Exodus – then it logically follows that Revelation draws from Enoch because its author believed Enoch was also part of the Old Testament.  Therefore, if one accepts the book of Revelation as divinely inspired, it is difficult to exclude Enoch, for Revelation implies that Enoch is likewise inspired.

     Saint Peter also makes reference to Enoch when he mentions that the condemnation of the evil angels was pronounced at the time of Noah's Flood.  Peter attained this information from Enoch chapter 10,

 

Enoch 10:2-3, 10:12-14 – The Flood is going to cover all the earth, and everything in it will be destroyed… bind them (the lustful angels) under the rocks of the earth for seventy generations, until their final judgment, the eternal judgment.  Then they will be led low into the fire, into torment, into prison, where they will be incarcerated forever.[1]

compare with

2^nd Peter 2:4-5 – For if God did not spare the angels who sinned, but cast them down into hell, and delivered them into chains of darkness, to be held until the judgment; and did not spare the old world, but saved Noah…

 

Notice how Peter's words in the New Testament assume familiarity with the Enochian legend.  Such evidence proves that Enoch was absolutely central to the worldview of the earliest Christians.

Other voices from the New Testament also quote the book of Enoch as if it were a scriptural authority, including Jesus, Jude, Paul, John, and Peter.  The book of Enoch should be in the Bible.
