The Only One That Fits
The prevailing modern view of the sin of Sodom and Gomorrah is that the attempted rape of Lot's visitors violated the Mid-East's high code of hospitality (19:9). This inhospitality, however, is an inference, not a specific point made in the text itself.
Further, the inhospitality charge is dependent upon—and eclipsed by—the greater crime of rape, yet neither could be the sin of Sodom and Gomorrah because God planned to judge the cities long before either had been committed. What possibility is left? Only one.
We know the men of Sodom and Gomorrah were homosexual, "both young and old, all the people from every quarter" (19:6), to the point of disregarding available women (19:5-8). After they were struck sightless they still persisted (19:11). These men were totally given over to an overwhelming passion that did not abate even when they were supernaturally blinded by angels.
Homosexuality fits the biblical details. It was the sin that epitomized the gross wickedness of Sodom and Gomorrah—the "grave," "ungodly," "lawless," "sensual conduct of unprincipled men" that tormented Lot as he "saw and heard" it "day after day," the "corrupt desire" of those that went after "strange flesh."
In their defense, some will cite Ezekiel 16:49-50: "Behold, this was the guilt of your sister Sodom: she and her daughters had arrogance, abundant food, and careless ease, but she did not help the poor and needy. Thus they were haughty and committed abominations before Me.
[8] Therefore I removed them when I saw it." No mention of homosexuality here.
Clearly, the general wickedness of Sodom and Gomorrah was great. That's not in question. Our concern here is whether homosexuality was part of that wickedness. Our analysis of Genesis shows that homosexuality was the principle behavior at issue in that passage. Ezekiel simply enumerates additional sins. The prophet doesn't contradict Moses, but rather gives more detail.
Stinginess and arrogance alone did not draw God's wrath. Ezekiel anchored the list of crimes with the word "abominations." This word takes us right back to homosexuality. The conduct Moses refers to in Genesis 18 he later describes in Leviticus as an "abomination" in God’s eyes.
