In order for a mormon woman to go to mormon heaven they must be called by their husbands.
That is the primary reason in celestial polygamy, it covers non married mormon women, otherwise they would never make it to heaven.
All a husband has to do is call her unworthy, and tell her he wont call her name and she will lock step to his desires (whatever they maybe).
I have a cousin who was called unworthy, then taken to the bishop who called her unworthy - it did not end well, as they both told all her friends, family and co-workers that she was unworthy and she was a temple worker (the inner circle so to speak).
Needless to say she was devastated and driven into a deep depression (because she was shunned), as I said it did not end well for her.
Yes, being called by the husband is a big deal, which is why some times mormon wives are referred to stepford wives.
Suicide, I presume?
