the angels yes. But never were OT saints or people called the Bene-Elohim or sons of God.
Now I am going to ask you to think. Why is there no mention of the "daughters of god"? Because angels are all male!
Notice the passage:
Genesis 6
King James Version
6 And it came to pass, when men began to multiply on the face of the earth, and daughters were born unto them,
2 That the sons of God saw the daughters of men that they were fair; and they took them wives of all which they chose.
Men in verse 1 is generic- it means mankind without distinction to spiritual state.
Then the B part of the verse simply declares- daughters were born unto them or mankind!
Verse 2 Teh bene Elohim saw the daughters of mankind were pretty! Were the daughters of God all ugly so that the sons of Seth would not have sex with them?? Is that another conclusion you want us to swallow as well? and if the line of Seth was already corrupted for the passage says mans thoughts were to evil, why would they still be called the sons fo God?
Your hypothesis requires you to draw too many conclusions that the Bible does not address at all!
but if we follow consistency and normal rules of grammar (exegesis) then the Sons of God were angels. And these are the angels in Jude who left their first habitation.
We know in the satanic rebellion, those angels became demons and are not chained as those angles who left their frist estate ( as jesus said in heaven the angels do not practice sex, which does not mean they are eunuchs)
Because the bible only gives the male linage
