@NS4Liberty pointed out that we would also call it "marriage" when a man is pimping out his wife to other men. Like Abram did... Obviously that is wrong. But if we are wanting to define exactly what we call "marriage", then we clearly don't actually think "only one man has sexual access" is necessary for us to call a relationship "marriage" - because we won't say it's not marriage just because that is broken.
I'm seeking the broadest definition which would encompass anything a missionary might see and label "marriage", because I think there is value in taking what we are thinking anyway and trying to put it into words.
So, how about my latest definition:
"Marriage is the assignment of a woman to a man for long-term sexual access"
- Is it broad enough?
Does it encompass everything a missionary might see in any culture, and label as "marriage"? Does it encompass every woman who would be considered off-limits because she's already married? Does it encompass every man that has obligations to a wife?
- Is it too broad?
Would it include anything that we would not label "marriage"?
