Previously, I noted the importance of hospitality in early pastoral civilizations and how the theme of hospitality to strangers is important in the epic poem The Odyssey. It is also a major theme in The Iliad. In particular, the downfall of Troy is occasioned by the Trojan prince, Paris, being a lousy guest in the home of Menelaus, the King of Sparta. In one sense, Paris having stolen away Helen, the wife of Menelaus, is an understandable slight from a romantic perspective: who wouldn’t be hurt and offended in this situation?
But it’s also understandable as a violation of the laws of hospitality. In fact, Menelaus describes it this way on the battlefield, after having killed the Trojan soldier Peisander:
“That’s how you’ll be retreating from the Greek ships, you insolent Trojans, always spoiling for a fight! Not that you are amateurs in other forms of abusive and shameful behavior. Look at how you abused me, you dirty dogs, when you broke the laws of hospitality and defied the wrath of loud-thundering Zeus, protector of guests, who is going to bring Ilium tumbling down before long.” (translation: E.V.Rieu)
So violating the laws of hospitality is a transgression of the order of things and provokes the wrath of the gods. I think a similar thing takes place in the book of Genesis when Sodom and Gomorrah are destroyed after the guests in the town are abused by the townsfolk without the permission of their host Lot, who is saved. In other words, I think the issue here is not homosexuality as much as hospitality.
