Can angels have sex with people?
We do not know for sure if angels can have sexual relations with women because the Bible doesn't tell us. Nevertheless, some Christians think it is possible and others do not and various scriptures are used for both sides of the argument. Let's take a look at some of them.
We can see from Matt. 22:30 and Luke 20:34-36 that angels do not marry, but this does not mean they can't take human form and have relations. I am not here advocating that they do have sexual relations with people. It is just that we cannot assert either position from this passage, especially when the Bible tells us that people have entertained angels without even knowing it (Heb. 13:2). This means that angels can take on human appearance to such a convincing state that they can't be distinguished from people. If this is the case, then it would seem logical that an angel (a fallen one) could imitate a human physical form including the sexual organs. On the other hand, I see no biblical support for such a manifestation of fallen angels in human form. Therefore, we are still left without an absolute answer.
Gen. 6:1-4 above is a more controversial passage. The question is who are the sons of God? Are they angels or people? Some commentators think that the Sons of God were the descendents of Seth:
"By the former is meant the family of Seth, who were professedly religious; by the latter, the descendants of apostate Cain. Mixed marriages between parties of opposite principles and practice were necessarily sources of extensive corruption. The women, religious themselves, would as wives and mothers exert an influence fatal to the existence of religion in their household, and consequently the people of that later age sank to the lowest depravity."1
Other commentators teach that the Sons of God were angels since the term "Sons of God" is used elsewhere to refer to angels as the following scriptures suggest:
However, the term "sons of God" also refers to Christians in the New Testament, "For you are all sons of God through faith in Christ Jesus," (Gal. 3:26). Since the question at hand deals with an Old Testament scripture, we must examine the context of that scripture to see how it is used.
Whichever the case, we do not know the abilities of angels. Given that they are very powerful and intelligent creatures, it is possible that they could manifest themselves as humans which has been verified in scripture: "Do not neglect to show hospitality to strangers, for by this some have entertained angels without knowing it," (Heb. 13:2). If this is possible that they can appear in human form and people not know it, then if a fallen angel would take human form, it would seem that it would be able to have sexual relations with a person.
