But if you really want to tell Kim Davis off for the hypocrisy of her so-called Biblical literalism, you need to knock off the personal attacks and take that literalism at face value.
That's how Planting Peace did it:
I'm not sure they got the parallel right, though. If they are referring to Exodus 21:7 (“When a man sells his daughter as a slave, she shall not go out as the male slaves do") it's more about slavery or indentured servitude than what we would call marriage. However, a DailyKos writer describes the same verse as "selling your daughter as a slave to be given to her owner or owner's son for sexual exploitation as a 'wife,' so I could be wrong.
There are lots of horrible definitions of marriage in the Bible, but perhaps this one was chosen for the pure absurdity of it in the modern west. But as far as I know, there is no real consistency of how marriage is defined in the Bible. Parts were written when polygamy was still standard, and others exhort married couples to ensure "the marriage bed kept pure, for God will judge the adulterer and all the sexually immoral."
Of course, all of this is moot because Kim Davis doesn't have a legal leg to stand on. But it's such a shame that people like her have become the face of American Christianity in the 21st century. I'm not a believer, but I still believe that Jesus the philosopher was all about love and acceptance.
