“There’s a push to separate Sacramental Marriage from Civil Marriage. Is it time to get on board yet?”
I think that is the fallback position and is a reasonable one should it be mandated that churches must not discriminate on the basis on sexual orientation. They may need to then create their own rules based on Church membership, being in good standing and not call it Sacramental bonding or whatever.
If people want or feel they then need to record a marriage with government institutions they will have to do it separately!
You can do that now, the thing is that people want their marriage to be legal, just knowing it yourself doesn’t help much, for instance being in the military with a wife and kids, yet not legally married.
