Leviticus is the source for the moral code that is cited in support of the Christian objection to gay sex. It talks about women quite a bit and at length. The first twenty out of twenty three precepts of sexual morality in Leviticus 18 focus on women. Leviticus talks about women, but not in relation to homosexuality.
It is true that Leviticus seems to be written from a hetero male point of view. Seems like if people saw homosexuality as intrinsically morally wrong, there should have been some mention of lesbian sex. Maybe something along the lines of: "Don't let your wife or female slave partake in lesbian sex because it is an abomination in the eyes of G-d, who created man and woman to be together." Or something like that.
The "oversight" would suggest that lesbian love was not an issue. This weakens the notion that the Bible supports a general anti-gay stance.
OK, I've been thinking about this. I admit that what follows contains a lot of speculation.
From what we see today, male homosexuals are the ones that will engage in sex in public--public restrooms for example. I don't think I've ever heard of a couple of lesbians having sex in the ladies rest room.
Children will emulate what they see in public, often in a mean and aggressive way, as children are apt to do.
{I've recently heard about a couple of fifth grade boys performing a homosexual act on another boy at at school, on the playground, during recess, as an act of aggression/bullying/mocking. I've also heard of a boy, the same age, dying because he and his friends buried him upside down in the sand box, just like they saw on a cartoon.}
When children start pickup up homosexual acts, and use them as a bullying/mocking tactic, the practice might become quickly ingrained within the culture. We can see evidence of this from the story of Lot and the two angels at Sodom from Genesis 19:4-5
4 Before they went to bed, the men of the city of Sodom, both young and old, the whole population, surrounded the house. 5 They called out to Lot and said, "Where are the men who came to you tonight? Send them out to us so we can have sex with them!"
The men, 'both young and old, the whole population" sounds like this was very much ingrained within the culture. When Lot protested, they
mockingly said they would "do more harm to him than they were going to do to the two angels." (Gen 19:9)
Perhaps the reason for the prohibition against men having sex with men might be due to the culture of public sex that has come to be associated with male homosexuality, which might then become a tool of mockery and aggression? Is that what the word
arsenokoitēs was about? I don't know. Perhaps.
