I saw a video (maybe Dateline?) where Lori's friend April was talking about that, specifically her being a single mom and how that felt as an active Mormon and I think she indicated that Lori didn't seem to look down on her like others did for that. I can't remember if she indicated the attitude had changed any.
The interesting thing about a temple wedding/sealing is that a man doesn't have to have it undone, does he? If they get a civil divorce, but the man can still convince his bishop that he's worthy of a temple recommend then he could marry as many women as he wanted in the temple, then divorce them on Earth, right? That would give him a regular harem of wives in the hereafter, at least in theory. I suspect that would become problematic (would the bishop let it fly?) but at least in theory it could happen. However, from what I've observed I think Mormon men see divorce as a non-starter as much as women as a general rule. But it doesn't seem it would have to be that way. If instead of divorcing the wives he was to have really bad luck with wives having accidents or bad luck with health and dying, it would be easier to get that lots of wives in the hereafter setup. I think someone suggested that might be Chad's approach although I suspect getting Lori to a legit sealing is going to be problematic. (Their own version of it might be another story.)
I can answer this question, at least to the best of what I understand.
So if a man and a woman are married and sealed (Two different things), then get a civil divorce this is what happens.
First, the sealing stays in place, unless either the man or woman requests to have the sealing cancelled (a difficult and lengthy process).
The man could legally get married again, but his original sealing (to the first wife) would still be in place. If he wishes to be sealed to (Wife 2), he needs to have the sealing cancelled first, then go through the proper channels to get sealed to wife #2.
So, in this scenario he can only be sealed to one living wife at a time (assuming all previous wives are all alive).
If he is married and sealed and his current wife dies, then he could marry another wife and also be sealed to her. So, technically he would be sealed to 2 woman. I think that scenario was discussed in detail a while back.
However, two things to note:
We believe that the sealing is only binding if the following conditions occur:
1- Both the husband and the wife live according to the covenants they made both in marriage and when they were sealed. If these are broken, the sealing is no longer recognized (spiritually speaking)
2- God is the authority that binds the marriage, so only he can decide if it is valid.
3- In the next life, we still have our agency. We can choose to not be with our spouse if that is what we want to do.
Second thing to note, is the early church history has members of the LDS split if polygamy (spiritual wifery), is actually part of God's plan. There are those that believe it is true, this is the official position the church takes on it. There are also those that believe that monogamy is the correct doctrine.
Not that it matters in this life what doctrine is true or not.
If I am missing anything important, please let me know. Thanks
Hopefully that answers your questions. MOO
