"Tough luck for him I guess. In the world of the LDS, he would either get the terrestial or tellestial heaven. Which isn't as good at the Celestial heaven. "
When a person has REJECTED and refused something, and doesn't repent of it all their life, they have to live with the eternal consequences of it. If circumstances prevented them from some required ordinance durring life, they still will have the chance to recieve those through temple work.
People who die young, or have some other circumstance preventing them in life are not automaticly cut off, only those who have set their heart against it and WON'T or wouldn't even if they could are.
"In this case, the hope of the Mormon woman to progress to the ultimate spot, hangs on the husband. If she is not called, she's done."
Not so. A person's exhaltation can not be stopped by anyone but themselves.
President Snow: "There is no Latter-day Saint who dies after having lived a faithful life who will lose anything because of having failed to do certain things when opportunities were not furnished him or her. In other words, if a young man or a young woman has no opportunity of getting married, and they live faithful lives up to the time of their death, they will have all the blessings, exaltation, and glory that any man or woman will have who had this opportunity and improved it. That is sure and positive"
President Benson said: "I assure you that if you have to wait even until the next life to be blessed with a choice companion, God will surely compensate you" http://library.lds.org/nxt/gateway.dll/Magazines/Ensign/1988.htm/ensign%20november%201988.htm/to%20the%20single%20adult%20sisters%20of%20the%20church.htm
A valid question would be, how did this situation come about? If the LDS woman was LDS before the wedding and made the choice to marry a nonmember, then SHE knowingly put her exhaltation at risk and is not blameless. I can not find any official statement that indicates that this is a mistake that cuts the person off from full exhaltation no matter what. I assume she can repent of it (and when forgiven, God would treat her situation the same way as for a single sister), but she will still have to live with all the conflicts that arrise from having an interfaith marriage.
If she converted after marriage and he did not, or if he fall away from the church, then she is not to blame and will not be made to suffer for it. She will be no more cut off from full exhaltation than the single sisters President Benson was talking to.
The same holds true for men, the actions of their wife can not prevent them from reaching full exhaltation, only their own choices.
If I die believing in Jesus Christ as my Savior and believing that Joseph Smith is a false prophet and that Mormonism is heretical where do I wind up in your theological understanding?
