Sodom and Gomorrah Sexual Immorality

Jude says Sodom pursued "strange flesh" - in Greek, sarkos heteras, other flesh. That adjective is doing specific work, and it is the reason Jude reaches for Sodom at all.
Heiser follows the argument bluntly: the phrase "cannot, as many commentators and most translations assume, refer to homosexual practice," and "must mean the flesh of angels." The logic is simple once you see it. Homosexual practice is sex with the same flesh, not different flesh. If that were Jude's point, why would he call it strange flesh rather than the same flesh?
So look at what Jude has just said in verse 6. Angels who left their proper dwelling. Then, in the very next breath, a city that went after beings from that dwelling. Two crossings of the same line, from opposite directions. That is why the two verses sit together.
Scripture links:
- Jude 6-7 - "the angels who did not stay within their own position of authority, but left their proper dwelling... just as Sodom and Gomorrah... indulged in sexual immorality and pursued unnatural desire."
- Genesis 19:1-5 - The visitors the men of Sodom demanded are identified as angels.
Jude is not making a general point about immorality. He is describing a boundary between heaven and earth being crossed twice.
