The Idea That Changed Europe So like most things, it was not the thing itself, but the principle behind it, in this case the lack of one, the dangers of blind indulgence, corruption and destruction of intellectual and moral values, and the resulting tendency of these things, especially when conducted in unison, to destroy societies and as a result end entire civilizations writ-large. — Outlander
I think you give sex far too much importance, as did Paul and others did after him.
I referred to indifference to sex in the Roman and Greek (perhaps I should use "Hellenic") world compared to what came later. It may be more accurate to say that sex didn't have the significance it came to have. Sexual relationships could be significant (like convenient marriages), but not so much the sexual act. I think that, then, people weren't as disturbed by it as they are now, particularly as to sex of certain kinds, it seems.
An example, ever been to the ruins of Pompey, or seen them on video? If so, you may have noticed the appalled reaction of some visitors, or the giggling of others, at the frequent depiction of the phallus and the occasional paintings or murals involving various sexual acts. Such things weren't thought forbidden or depraved at the time; a phallus could even be considered "lucky".
We come to attribute too much significance to what we think is forbidden, especially when we believe it's forbidden by God. This strikes me as particularly the case here in our Glorious Union. So we tend to see such as Anthony Comstock, Carrie Nation, Billy Sunday (who was it seems a good baseball player) and other preachers against purported vices of all kinds). We also see others who like to appear to glory in those vices thinking it makes them remarkable in some sense.
