Looking back at the original question, I was reminded of a wedding I performed at (I'm a violinist) this weekend. Drove 2 hours from my urban home to the middle of "Podunk" Georgia. Ceremony was held in a large Baptist church.

The bride was about 22. Groom was maybe 26 and an Air Force captain. It was emphasized that this was a "Christian" marriage a couple of times. Vows included the following:
- Wife agreed in the statement of intent ("I do" part) to submit to her husband in all things.
- Wife's vows (which the couple apparently wrote themselves) included "obeying" her husband.
- At 3 different places in the ceremony the passage from 1 Corinthians about the "husband is the head of the wife" was mentioned.

I found myself thinking that it almost sounded like a "master-slave" ceremony, except that her parents were sitting there... Maybe they meant "Christian" marriage as in the type of about 2000 years ago? :/
