While some churches call the bans of marriage "vows", marriages are mostly civil/social contracts both now and in Jesus' time.
This is still kind of my point. Yes, modern marriages are mostly civil/social contracts. A legal document under the power of the State binding two people together. Otherwise known as a written vow, or a written promise to do what you say you're going to do. The State, according to JW's and many Xtians, is under the power of who? The wicked one of course. So yet again we're at a point where modern marriage is an institution "from the wicked one". Just because it offers protections within Satan's civilization doesn't make it any more in line with Jesus' teachings. Correct?
