The mystery of the seven stars which thou sawest in my right hand, and the seven golden candlesticks. The seven stars are the angels of the seven churches: and the seven candlesticks which thou sawest are the seven churches.
— Revelation 1:20
There’s some scripture that conflicts with what you’re stating. The angels of the seven churches received epistles from John.
Is your point that John never actually gave a copy of the book of Revelation to any human? Then I guess you can explain how any one received a copy of the book then, and how it was distributed.
If your argument means angels were actually on earth as the leaders of these churches instead of humans, then you must think John was not even born a human but was a mere angel himself like Paul? Evidently God allows humans to be able to kill even angels?
I guess you can justify your erroneous doctrine that states God allows some angels to leave their estate and live on earth, based on the symbolism in the book of Revelation?
Personally I don't see stars as humans do, just bodies of gas out there in the cosmos. Do you think all those stars a few hundred miles away from the surface of the earth make up a gigantic universe or just a lot of angels only a few hundred miles above the earth? Why would a star/angel not stand as a guard or representative over a church, in the spiritual fight of demonic forces sent by Satan to destroy that church? Ephesians 6:12
"For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places."
Don't you think humans can, in prayer and obedience to God, wrestle against demonic forces, or do some humans have to be literal angels?
I think the point was that John was supposed to write what he saw. Even if what he wrote was to be given to an actual angel. That still is not proof angels are humans, nor sons of God. It could mean that Satan has the whole world deceived about the stars and some non existing universe. This virtual universe that will dissolve at the Second Coming, along with the erroneous notion angels are the sons of God.
Angels are the stars created on the 4th Day.
The sons of God are adamkind/humankind created on the 6th Day.
That is why in Job we are told the angels sang, and the humans shouted back that first week of creation. Obviously humans were giants compared to Adam's dead state that he was placed in after he disobeyed God, and thus introduced sin into creation, that had not been there prior to Adam's disobedience. Adam did physically die. He was no longer a son of God, but now the father of dead corruptible flesh. As a son of God, Adam was not a sinner. Now in dead corruptible flesh, Adam lived in the bondage of sin and death. Adam and Eve passed that state of physical death on to Seth, and all their offspring after Seth.
"And Adam lived an hundred and thirty years, and begat a son in his own likeness, and after his image; and called his name Seth:"
Adam was no longer a son of God, and passed the image of sin and death on to Seth.
The other point is that male offspring of Adam and Eve cannot carry a conception to term in their womb. Thus not viable to the sons of God. The daughters, or female offspring could carry a conception to to term.
