My church doesn't consider Enoch canonical, so I approach it with caution, if at all.
That doesn't mean I consider everything in it wrong. I don't. But I believe that if it were worthy to be considered scripture it would be in our Bibles today.
You were looking out for some other authority to convince you of things on more than one thread, and the authorities you were seeking are not Canonized authority.
The link you gave is not canon, but you are convinced by him of something, while all the time the entire foundational doctrines are all laid in "Enoch the prophet the seventh from Adam" and all those fully laid out foundational doctrines are corroborated in the Tenach and NT.
Satan is an entire class of evil spirits with one Chief. Their dwelling is in heaven until they are cast down, then they are bound up for the millennial reign; and then let loose for one more gathering up of a harvest of souls which will be food for them forever, to feast upon in the Lake of Fire.
The Lake of fire is prepared "for the devil and his angels". It is their kingdom of darkness, and they have to gather their harvest in for food forever while they have the time....
Their food is to torment and afflict and punish:
#1 fallen unrepentant Adam souls [cast into the Lake of Fire forever, "soul in body" [and forever in their own bodies which Jesus died to cover the sin of Adam for, and they are resurrected and/or cast in alive at His coming, who never repented of their own sins].
# 2 fallen holy angels =the Watchers who fell and fall.
# 3 the demons who are at this time roaming earth as evil spirits dwelling on earth, while the satans are evil spirits dwelling in heaven.
At this time, the demons are subject to the satans. CS Lewis got it right out of Enoch for his fiction book, The Screwtape letters, but he added his fiction to it: he read Enoch and Jasher before he incorporated things from them for his fictions.
To believe that Satan is a fallen holy angel named Lucifer
is an unbiblical myth without support in the Word of God, but many Christians think that is Bible doctrine based on nothing but hear-say and tradition.
Enoch lays it all out, and it is in Enoch as "Thus saith God the Great Glory from His throne", when he spoke to Enoch those words.
The evil spirits whose dwelling is in heaven are satans with one chief. They were made to do what they do, and for doing it well, they are rewarded with their own kingdom of darkness forever, in which they will afflict and torment their captives, which is their "food".
in 1 Kings A Satan, a lying spirit in heaven, serving God, seen in heaven:
1 Kings 22:
And he said, Hear thou therefore the word of the Lord: I saw the Lord sitting on his throne, and all the host of heaven standing by him on his right hand and on his left.20 And the Lord said, Who shall persuade Ahab, that he may go up and fall at Ramothgilead? And one said on this manner, and another said on that manner.
21 And there came forth a spirit, and stood before the Lord, and said, I will persuade him.
22 And the Lord said unto him, Wherewith? And he said, I will go forth, and I will be a lying spirit in the mouth of all his prophets. And he said, Thou shalt persuade him, and prevail also: go forth, and do so.
23 Now therefore, behold, the Lord hath put a lying spirit in the mouth of all these thy prophets, and the Lord hath spoken
Another Satan serving God by cursing King Saul after he rebelled -which rebellion is as the sin of witchcraft:
1 Samuel 16:14
King James Version (KJV)
14 But the Spirit of the Lord departed from Saul, and an evil spirit from the Lord troubled him.
And Paul had an angel of Satan sent to "buffet him as a thorn in his flesh" to keep him from exalting himself above measure because of the abundance of revelations [understanding what is written in the Word]
Satan has to ask permission to test God's people, and Jesus said Satan had asked for Peter, to sift him like wheat, but Jesus prayed for him to make it through and to strengthen his brethren afterwards.
There are Holy angels whose eat and drink is to worship and praise God. The opposite is true of the Satans, who are unholy angels whose eat and drink is to curse the Adam creation they deceive with lies, and also the fallen Watchers who became subject to them by receiving their lies, and the demons -who serve them now, but will be tormented by them in the Lake of Fire.
At this time, before they are bounded in their kingdom of darkness, their food is to "eat dust", of this creation which is the dominion of Corruption/Destruction and Death that this creation is cursed by the Creator to be subject to the satans to, becasue of the defilement of its -now dead in spirit- firstborn son, the king, and the priest of it; Adam, and to hold the departed and captive unrepentant souls in Sheol, "in the belly of the earth", until the day of judgment.
Jesus comes to free us from the curse and we are no longer captive to that death which is spiritual, since we are born again, but we are still in the bodies of death that "satan" has dominion over because God gave it to "him" -the entire class of evil spirits called Satans.
By God's mercy and favor we can come boldly to the throne of grace and receive deliverance from the curses over our bodies, as we seek him for individual afflictions to be removed, but until Jesus comes to remove the curse from the earth and bind the Satans this present creation will be subject to Sin, Death and Corruption: They are "Satans" in the very "dust" of this present creation since the fall, and all the animal kingdom suffers from the same, and shall all be free when Jesus comes to reverse the Curse and bind the Satans and the "sons of God are manifest".
The only human being ever born since the fall of Adam in whom Satan -the whole class of evil spirits- has had "nothing in", is the New Man flesh body of the LORD Jesus Christ. His body could not corrupt because there was no "Sin/Corruption/Destruction" in His flesh of New Man creation.
John 14:30
King James Version
30 Hereafter I will not talk much with you:
for the prince of this world cometh, and hath nothing in me.
Satan is not a fallen holy angel, but an entire class of created evil spirits/princes who have been given the dominion over "the dust of this creation" and Sheol below, and over the Lake of Fire forever.
