God did not design for ANY of the species to cross-populate with each other. Hence the laws against bestiality in the OT.
Beastiality does not produce offspring so the laws against it had nothing to do with offspring.
This wasn't just humanity's flesh corrupting itself on earth. It was the sons of God marrying human women who had also corrupted their own flesh with those forbidden unions.
You have yet to prove scripturally that "sons of God" in that passage refers to angels. That expression only
sometimes refers to angels. All the redeemed are called sons of God, which only adds more credence that the Seed bearer was in focus here, and that line being corrupted by the practices of extremely corrupt and powerful men. Read about some of them that are related to the ones listed in Gen chapter 5. The chapter that leads to chapter 6. The Law had not yet come---those unions were not forbidden. The passage does not say they were forbidden unions. It tells us the result of it which is increased corruption, more and more vile. No different that what happened with Nimrod and His tower that prompted God to confuse the language and scatter the people. (A very interesting take on that can be found in
Far As the Curse is Found: The Covenant Story of Redemption by Michael D. Williams.)
And I believe it is possible that angels united themselves with the flesh of beasts as well in those days (giving rise to all the half animal / half human mythological creatures - Centaurs, mermaids, Sphinx-like creatures, all the Egyptian type of human/animal gods, etc.).
Saying things like that removes credibility. Basic biology shows us that even if differing species mate, the union cannot produce offspring. The necessary ingredients to do so or their ability to mix are not there.
God told us that in marriage, the two "become one flesh". With the sons of God marrying human women in Genesis 6, those angelic sons of God corrupted themselves by becoming united with the fallen daughters of Adam. Uncleanness resulted for those originally-righteous angelic sons of God. The hybrid angelic / human sons which their human wives gave birth to that grew to be giants were likewise born with an unclean spirit (which explains why there are multitudes of "UNCLEAN spirits" possessing many in Israel in Christ's days).
Credibility on the subject---- gone.
One flesh means joined in purpose and duty. Not that they now become a two headed, four armed etc. hybrid but an indivisible unit. It is the design that has been corrupted---not by fallen angels---but by fallen sinful man. The buck stops there.
A redeemer of fallen mankind was REQUIRED to be made just like them in order to take their place as their representative High Priest. If the human race had remained corrupted by being mingled with the angelic species of the sons of God, then there would have been no way for God to redeem the fallen human children of Adam.
The human race did remain corrupted since Adam, and not by fallen angels but by their own actions, thoughts, words, intents, desires. And even if what you said were true----and nonsense is never true---God could still come to us as the Son, Jesus, just as He DID. Do you not believe in the deity of Christ? I can't figure out your thought processes to arrive at the above. It did not take fallen angels propagating with human women in order for all of mankind to become corrupt. All it took was one bite of the forbidden fruit.
Satan wasn't stupid. He knew it was going to be the "Seed of the woman" who was predicted to crush his own head. Satan and the fallen angels did their best to ruin the race of mankind by interjecting the angelic species within it
The human race was already ruined. It had been since "she gave to her husband and he took and ate" and they were cast out of the Garden and away from the tree of life. Not even Satan that old serpent of old corrupted mankind. He only tempted them. Adam and Eve did the corrupting themselves.And we do likewise. It did not take angelic beings to do that. I have to lose my cool here for a second and ask "What is wrong with you?"
Where is this coming from? It is so anti biblical it is taking my breath away.
Again, I have not said that angels have DNA, and we don't know if their bodies had blood or not. That isn't the point. It was the fact that by their marital unions with the daughters of men and becoming "one flesh" with them and bearing hybrid angelic / human sons by them, they cross-populated the species which God designed to remain separate from each other. Christ didn't come to redeem angels. He came to redeem fallen mankind and become their representative high priest. To do that, He had to descend from a bloodline of a human-only species with no angelic mingling with it.
There is no such thing as cross populating of species. I think you need to go back to the beginning---Gen 1---and see exactly what God's order of creation is. Seriously.
Yes, Mary was likewise in need of a Savior as a fallen daughter of Adam. But God did not design for females to carry the representative role as Adam did. Christ needed to come from Mary as "the Seed of the woman" , but He simply could NOT come from an earthly father, because that would have endowed Christ with a sin nature through our representative Adam.
So why did God have to destroy all these cross populated and cross populating angels and humans again? You are boxing yourself in. Take heed, and change direction. Plus in your theory you have all these hybrids destroyed in the flood, those evil angels bound, and yet their offspring showing up in Canaan long after the flood.
That's good, because I have read others who do claim that angels never had a body form of any kind that could have engaged in marital relations with the daughters of men.
Just because they have a body does not mean they can engage in martial relations with the daughters of men. They do not have the same type of body as humans do. Remember 1 Cor 15?
Being "equal to the angels" in a resurrected person having a deathless body form like the angels in heaven is very much a description of what type of body that resurrected humanity will have. Our bodies in the resurrection process will share the same deathless condition that the bodies of the elect angels now enjoy.
Keep a distinction between the resurrected saints and the resurrected unbelievers. They do not receive the same fate. Jesus did not become and angel in His resurrection and He does not resemble an angel now. The resurrected Jesus---a resurrected human body--is what we will be like. 1 Cor 15.
As man, Jesus had human flesh and his human flesh died. Like we will. His human flesh was raised. He was recognizable. He had the wounds of his crucifixion on him. He was the first fruits of the resurrection, and our resurrection will be like his. Our bodies will come out of their graves if we have died in Christ before his return, immortal, imperishable, incorruptible. If we are alive when he returns, we will be changed in the twinkling of an eye, at the sound of the trumpet. But we will not have the same type of body as angels.
