I have two things. First a question and then a comment.
The question:
The arguments about whether the events in Gen chap.6 really happened aside, and assuming that the "sons of the true God" were angels and the "Nephilim" were their hybrid offspring - Where does the idea come from that these angels materialized human bodies and lived like men? And then, of course, the flood would have forced them to return to their original spirit selves.
For several years I have tried to figure out how the Society came up with that aspect of the story.
Jude 6 says they "did not keep their original position but forsook their own proper dwelling place."
Peter says they "had once been disobedient when the patience of God was waiting in Noah's days" (1 Pet 3:20) and "sinned" (2 Pet 2:4).
Genesis 6:2, 4 says "the sons of the [true] God began to notice the daughters of men, that they were good-looking; and they went taking wives for themselves, namely, all whom they chose ... the sons of the [true] God continued to have relations with the daughters of men."
Of course, they had to do it in some way. But these verses are the only ones I know of that describe those events and they fall short of saying anything about where they lived or how they accomplished their deeds or what type of bodies they assumed. Yet the Society describes it and illustrates it as if it was beyond questioning.
That is my question, but what follows is what I've considered as impacting my viewpoint so far.
"Wives" in Gen 6:2 is simply a translator's choice. "Wives" could just as rightly be translated "women" or "females." I have a problem with "wives" because Jude 7 describes the people of Sodom as having "committed fornication" like these angels. If the women of these angels were really their "wives," could the angels be described as 'committing fornication' with them?
Another problem I have with the idea of the angels living as men is that Genesis 6:4 says, "the Neph′i·lim proved to be in the earth in those days, and also after that, when the sons of the [true] God continued to have relations with the daughters of men." The verse isn't conclusive, but the statement about 'the Nephilim being in the earth in those days' would seem like 'less-than headline news' if superhuman angels were living there too.
"Have relations" in Genesis 6:4 is interesting also. The KJV is more literal, saying "came in unto." (ESV has "came in to") I've read that this might have the idea of an invasion, with the possible idea of rape or something like that. Maybe I'm mistaken, but somehow I've acquired the idea that in those times it was more customary for the women and men of a family to live in seperate quarters and for the man to bring his wife or concubine to his quarters for relations. That is why the word used for "have relations," or more literally "come into" suggests to me that these angels did not live like married men.
The final problem I have with the angels living as men is one of logic. If they are capable of changing form/ materializing at will, why give up a spirit body for one that has to go to the bathroom, eat, sleep, travel at much less than light speed, use doors, etc. Why not just materialize - if they need to do that - make love, and then go back to the spirit realm? (The best of both worlds, as it were.)
At any rate, that is the extent of my research on the matter, and since this was part of the (extended) topic, I was curious to see if there was any more opinions or info that could be added or used to correct.
Since the question turned out to be so long, I'll save my comment for later. It was about the phrase "marry and being given in marriage."
Thanks and Take care
