This is a good article, with some good facts about some views of homosexual people in ancient Rome – Biological Influences on Same Sex Attraction According to Rome.
We often hear people say that the apostle Paul or other biblical authors didn’t understand the biological causes of homosexuality (or even transgenderism) and therefore whatever the Bible says about them doesn’t apply. But as this article points out, there were writers of the time thinking about people being born with different desires. They thought about possible biological causes or a possible soul defect. Of course they didn’t understand the biological truths we know today. But the idea that there was something ingrained about homosexual or transgender desires was around.
I like the author’s conclusions about the ramifications for biblical interpretation concerning this. It is not fair to say that if Paul knew about the true causes of homosexual desires, that he would not have condemned homosexual behavior as sinful. The fact is, many of the views surrounding homosexuality today were also around back then, and yet Paul still condemns homosexual sexual acts as sinful.
