In medieval times, the Church used to have an Impotence Test. Since the only reason Church would allow a divorce was if the husband was impotent, they usually didn't believe married couples claim that hubby was impotent, so they had certain women who would test the guy if his dick can get hard by arousing him and playing with his penis.
teachings of the Bible are so muddled and self-contradictory that it was possible for Christians to happily burn heretics alive for five long centuries. It was even possible for the most venerated patriarchs of the Church, like St. Augustine and St. Thomas Aquinas, to conclude that heretics should be tortured (Augustine) or killed outright (Aquinas). Martin Luther and John Calvin advocated the wholesale murder of heretics, apostates, Jews, and witches. - Sam Harris, "Letter To A Christian Nation"
