Perhaps because it's content speaks of a spiritual war...it was decided that the more general population would just not understand it and even become frightened by it or that they may learn things they really shouldn't know...if we are to encounter a spiritual war the likes of which none of us could concieve...we may see armor in its content instead of darkness??? Maybe???
Maybe
something along those lines ...
I might view it a bit more like this, along those similar lines, but taking into account an idea from the following scripture from 2 Thessalonians:
"Concerning the coming of our Lord Jesus Christ and our being gathered to him, we ask you, brothers and sisters, 2 not to become easily unsettled or alarmed by the teaching allegedly from us—whether by a prophecy or by word of mouth or by letter—asserting that the day of the Lord has already come. 3 Don’t let anyone deceive you in any way, for that day will not come until the rebellion occurs and the man of lawlessness[a] is revealed, the man doomed to destruction. 4 He will oppose and will exalt himself over everything that is called God or is worshiped, so that he sets himself up in God’s temple, proclaiming himself to be God.
5 Don’t you remember that when I was with you I used to tell you these things? 6 And now you know what is holding him back, so that he may be revealed at the proper time. 7 For the secret power of lawlessness is already at work; but the one who now holds it back will continue to do so till he is taken out of the way. 8 And then the lawless one will be revealed, whom the Lord Jesus will overthrow with the breath of his mouth and destroy by the splendor of his coming. 9 The coming of the lawless one will be in accordance with how Satan works. He will use all sorts of displays of power through signs and wonders that serve the lie, 10 and all the ways that wickedness deceives those who are perishing. They perish because they refused to love the truth and so be saved. 11 For this reason God sends them a powerful delusion so that they will believe the lie 12 and so that all will be condemned who have not believed the truth but have delighted in wickedness."
From the beginning of the accounts in the scriptures, you can see where man kind chooses time and again to go their own way, or the way of others in opposition to God. Or, they continually choose other mediators instead of God Himself. Instead of dealing with God directly, they chose Moses to do so. Instead of having God as King over them, they wanted men like the other nations. Instead of working through the desert to the Promised Land, they preferred slavery in Egypt. False gods, luxuries of the flesh, magic, sorcery, serving other spirits ... humans continually build societies that attempt to be "Godless".
In Enoch, we see even farther back, to where some of the origins of the very things that help to make society what it is, come from. Everything from weapons, to cosmetics, to weather, to writing. If you put it into a certain type of context, it's as though the beginnings of what we call "civilization" were mostly the result of Watcher influence. What they thought culture could be like, is what we "became". Fast forward to Babel, where the plans of mankind were thwarted ... and you begin to see a sort of perspective take shape:
With the influence of fallen Watchers, and spirits, and mankind combined ... a type of advancement happens in society, but one that leads to Godlessness, enslavement, and destruction.
Yet ... this is typically the very type of society mankind has strived for, to achieve.
So now consider the idea that if you remove the fallen Watchers from the equation for a time, that their influence would continue to grow and expand. Especially so if the disembodied spirits of their offspring were still on earth, and able to influence and occupy other living things (like people obviously). It could make sense that the spirits, and/or sympathizers, would try to disconnect mankind from some of their actual origins, and cast confusion and doubt upon ideas like "Watchers" and "angels influencing man", etc. ... all whilst furthering their agenda, and the growth of their own societies and influence on earth.
Opponents do this all the time: manipulate each other, use misinformation to confuse and hide agendas, etc. Governments use spies, dictators use lies. Often times, if you can control information and resources, people can be motivated to do things that otherwise would be detrimental to themselves. Look at the way people slave away for "money", or specific luxuries and such. Look at what people go to war over. And look at how easily people are deluded, and believe lies ... even to the degree they do not realize the evil atrocities that are taking place in their own backyard. Nazi Germany and the concentration camps are a great example, as are some of the atrocities the North Korean government has committed on it's own people. The United States is no exception with some of the experiments performed on the public, admitted to later by the government.
In other words .... delusion is a powerful tool, and one that people actually accept and end up condoning, if it suits them. Do you really care if your boss means what they say, so long as you get the nice paycheck ? Do you really care if you are lying to your child, so long as it makes them smile ? Do they care ? So it's already in our nature to often desire delusion in order to cope, and live on earth ... so it's not a stretch to consider the idea that over the centuries, the enemies of God have helped to push a *secret power* that is at work, to further the goals and agendas of those behind the power.
Now imagine what an advantage it would be to you, if you wanted to enslave a society ... what an advantage it would be if not only did they not believe in your existence, but even if they did, they wouldn't even care, because you have rewarded them so greatly for their loyalty, service, etc. ... to the degree that they have taken your own desires for them as their own and are in full agreement with you. So even if you remained in the shadows, pulling the strings ... it ultimately didn't matter. They would still willingly want the world to turn out the same as you did, to their own demise. What I might do then, to achieve that goal ... would be to try and erase all ideas that I was "evil", and pull the strings in secret. I would wait, and let them get to a point of complete agreement with me ... and then, when it was "safe to come out", I would make myself known. By then, they would no longer view me as mythical, or even an enemy ... they would view me as beneficial, because they had been *
soaking in my goals for them all along, to their own ignorance*. Perhaps I might obscure the ideas of what I even look like, so that when I was revealed, they wouldn't even recognize me ... their ideas of what spiritual beings should look like having been completely skewed and misinformed through delusion.
Now fast forward all the way to the events in Revelations, and you begin to see the Beast, the Dragon, the angels, the whole world worshipping this and that, things that "once were, now are not, yet will come", things coming up from out of the Abyss, secret powers of lawlessness being revealed, those whose names aren't written in the Book of Life being astonished ... and people believing powerful delusions and lies and serving evil ... and you begin to look around you at the state of society today, and things start to fall into place.
Had the Book of Enoch been canon in the early centuries, perhaps, and it's ideas been viewed as a "manual for spiritual warfare", then perhaps as modern civilization and culture was attempting to bud, there would have been more people who viewed it's growth as spiritual, and perhaps seen the Enochian accounts as enlightening them to fight a spiritual war, and refuse to bow down, and refuse to partake in the growth of a system of lies, deceit, and evil. Perhaps those in power and authority would have been more easily threatened by those who fear God, etc., and things like the joining of church and state would have been avoided. The church would have become a bastion for those who stand up against "the system" and the power behind it, rather than marrying it and working with it to build empires. So in that regard, one can see why perhaps there might have been a desire to suppress these types of accounts, or mar them, or warp them ... would the general population not know what to do with such knowledge ? Or perhaps would they actually be SAVED with such knowledge and so, the less they know the better ?
But now, in today's society ... anyone with a computer can read these accounts. And if you believe some of them, and begin to put the pieces together ... is it really going to effect the average person's life ? The average person is already familiar with ghosts, spirits, angels, demons, aliens, the supernatural, etc. There are a million and one tales, accounts, explanations, theories, religions, etc, to tell him what to think and consider. The ignorant view it as ENTERTAINMENT. Furthermore, if the average person began to view their own country and society as a "tool for the Beast" and the power of demons and Watchers at work ... would he change ? Would he quit his lifestyle ? If he learned that all those deals, contracts, and pacts he made throughout his life ... and all the good that science had discovered and attained, were actually to achieve some other goal and end, would he actually stop participating now ? So from that perspective, what would it matter anymore if the Book of Enoch was canon or not ? Even if the general population viewed it as a guidebook for spiritual warfare, and that it was vital information that we all should really know .... would anyone really care and see it as armour in a way that would matter any longer ?
