Some are trying to make a connection between Jude 1:6-7 to say it proves angels fornicated with humans. It say nothing of the sort. Their reasoning goes like this: the angels left their home in heaven to come to earth to fornicate with humans (verse 6) even as the men of Sodom did (verse 7). But that's not what the text says.
Jude 1:4-7 is a warning to be wary of ungodly men whose destiny is destruction. Jude 1:4 says ungodly men had crept in who were ordained to condemnation, and then 3 examples of this in former times are provided in verses 5-7
- I will therefore put you in remembrance, though ye once knew this, how that the Lord, having saved the people out of the land of Egypt, afterward destroyed them that believed not. Jude 1:5
- And the angels which kept not their first estate, but left their own habitation, he has reserved in everlasting chains under darkness unto the judgment of the great day. Jude 1:6
- As Sodom and Gomorrha and the cities about them similar to these gave themselves over to fornication, and went after strange flesh, are set forth for as an example of suffering the vengeance of eternal fire. Jude 1:7
A very similar passage occurs in 2 Peter 2:1-6. Verses 1-3 say there are false prophets in the church who will bring swift destruction upon themselves, and then 3 examples are provided of the ungodly being destroyed in former times in verse 4-6:
- For if God spared not the angels that sinned, but cast them down to hell, and delivered them into chains of darkness, to be reserved unto judgment; 2 Peter 2:4
- And spared not the old world, but saved Noah the eighth person, a preacher of righteousness, bringing in the flood upon the world of the ungodly; 2 Peter 2:5
- And turned the cities of Sodom and Gomorrha into ashes condemned them with an overthrow, making them an example unto those that after should live ungodly; 2 Peter 2:6
In this case there is no connection between the angels that sinned and the Sodomites that sinned, which disputes the connection between angels and Sodom some are trying to make in Jude. In all cases all examples are used as warnings of what happens to the ungodly
