Why is the Book of Enoch not considered canon?
I have been reading through various apocryphal texts recently. Many of them I fully understand why they were excluded (i.e. the Nag Hammadi texts).
But I don’t understand why the Book of Enoch was not canonized. I consider it to be a very valuable text that does not seem to contradict scripture or the Gospel. It further provides details about the Fallen Angels, the flood, the Nephilim, proclaims the coming of the messiah, and even describes God as a man!
Many of the Church Fathers/theologians from antiquity seemed to view it in high regard. Justin Martyr used it as a source when writing his book the Second Apology about the Fallen Angels. Tertullian went as far to state it was divinely inspired & stated that non-believers and Jews rejected it because it plainly tells of Christ.
Many scholars view Jude 1:14-15 as a direct citation of the Book of Enoch. Yet, only the Oriental Orthodox consider it part of biblical canon.
Why was it not canonized? Does anyone else find it to be a valuable & reliable apocryphal resource on the Fall?
