It wouldn't matter to me as a pastor she wanted to keep her maiden name. I could see if she were a doctor, lawyer, or other professional why it would be important to keep the maiden name. I don't see her taking her husband's last name as a sign of submission in a Christian marriage. It's her actions that indicate that submission.
As far as wearing white when not a virgin goes, what difference does the color of attire make? Before Queen Victoria's wedding, there was no tradition of a color a woman, virgin or not was to wear at her wedding. Queen Victoria set that fashion trend when she wore white for her wedding.
It is interesting just how many traditions we have from Britan. It .akes sense as we started from British colonies, but we also have people that immigrated from Italy, Spain, France, Chile, Greece, etc.
Marriages are about the union of a man and woman. But marriages are also about cultural traditions.
I see nothing wrong with couples (like my wife and me) who hold the tradition of the wife taking her husband's name. But at the same time I cannot elevate my traditions as superior to the traditions of other people.
The wife taking her husbands last name has
absolutely nothing to do with submission or even Christianity. It was British common law (the couple was identified as one legal entity). We inherited that as tradition.
With the rise of feminism it became a matter of submission with some because a relative miniscule number of feminists used keeping their madien name a symbol of independence. Adopting the husbands name became a reactionary belief among some believers.
Throughout the history of the US cultures have not adopted the British custom. They maintained their marriage traditions and customs. It was not an issue until the rise of feminism.
