See Dr Michael Heiser for further information The book “The Unseen Realm” by Dr Michael Heiser gives a lot of detail on this sort of thing. The linguistic and historical evidence leans very strongly towards Genesis 6 referring to fallen angels procreating with human women, as well as to the historical veracity of 1 Enoch (though that book is not inspired/inerrant/infallible).
Two things about the passage in Matthew: That passage doesn’t say that angels CAN’T marry, it only says they DON’T. It also says that “angels in Heaven” don’t marry, but Genesis 6 is specifically referring to angels who left their Heavenly abode and took up with human women (all in rebellion against God).
Unfortunately, a lot of literature on this topic is a load of sensationalistic nonsense about the End Times. However, I would highly recommend Doug Van Dorn’s book “Giants: Sons Of The Gods.
Another thing to mention is that just as there are civilizations around the globe that have legends and stories about a worldwide flood, many of those same civilizations ALSO have legends and stories about giants — including in the Americas.
You get what you pay for This is what happens when you allow civil government to define marriage. Once you allow the State to define marriage as one thing, you’ve automatically given them the right to define it (and redefine it) as whatever they wish. Marriage privatization was (and is) the only way to go in order to avoid this sort of thing.
We need more Rand Pauls Good, I’m glad CPAC loved him. He is easily the best Senator we have on Capitol Hill. Here’s hoping the rest of the country catches up with CPAC.
