Again, while I agree more with Ladislaus on this issue, everyone here acting as if capital punishment for adultery is some Islamic or тαℓмυdic barbarism is still ridiculous. While it was far from the most common punishment(punishments like public humiliation and exile to a convent were more common, usually with the spouse getting a say in how severe it should be), the death penalty was still dished out in many Catholic countries for adultery. And that wasn't a secular abuse - the Bible condones it, and Flavius quoted a pope supporting it in the OP.
So honestly you can relax with the insults and insinuations.
