(I'm not looking for a long explanation here. I already accepted the explanation. So, peace.)
The "Gay Christians" --- I'm not blaming you --- are using exactly the same historico-critical method to deconstruct the Pauline texts on homosexuality. This is not exactly pleasant reading, but I urge you to check it out:
Gay Scriptural Cultural interpretation (LINKS)
If you read the top article that comes up from the link, check out the rest of that gaychristian101.com website. As you can see, they are very enthused about Scripture.
By all means we SHOULD take into consideration the historical and cultural context of Scripture but it is not an excuse to totally disregard the truth underlying the passages. So-called "gay" Christians don't use an honest hermeneutic when they say they can justify their perversion by Scripture any more than a JW can justify teaching Jesus was "a" god and not THE God incarnate. Selective reading to prove a pet theological idea is nothing new, though. The first church councils were designed to set down enduring creedal doctrines based upon sacred Scriptures as the Divinely-inspired authority for truth.
Homosexuals do not have a valid argument for their abominable acts and are being DISHONEST with Scripture, excluding and ignoring key passages in order to rationalize what they know deep down God condemns. This is why I do not believe it is the same argument as the one we have been discussing WRT women teaching men. The basic principle behind Paul's instruction is sound and accepted.
