These are more of observations than a proposed answer. But I think any real answer needs to account for them.
1. Nowhere in the Bible is there any example of a couple being married before anyone in office (not priest, Levite, prophet, apostle, etc.) or anyone being advised to. Yet, our Christian culture demands that there be a religious service wedding, with a pastor or minister officiating.
1a. Jesus is the bridegroom and we are the Bride. Who performs that wedding?
2. The prohibition against multiple spouses derives Scripturally from two places where deacons and bishops are required to have only one wife. It is nowhere in the OT. And certainly, not everyone is a bishop or deacon.
I think this is a question with many possible directions it could go, depending on who participates.
