Sin of Sodom: Inhospitality, as in Lot’s wife entertaining his guests with pretzel nuggets and celery sticks filled with generic cream cheese and saving the salted almonds and brie en croute for herself, thus bringing divine annihilation upon her fellow townsfolk.
(For other items in Lexicon, see First Things, October 2000)
It does not sound like St. Jude had inhospitality in mind when he said the Sodomites "indulged in unnatural lust." (v.7) See also Ezekiel 16:50.
