I know people who have omitted the “'til death do us part” clause from their wedding ceremonies for three very different reasons:
1) They believed that their marriage would last past death, despite the official creeds of their religion. (Quite a few fit this category.)
2) They had a degree of religious commitment and didn’t want to make a promise “before God” they might not be able to keep. (Only a couple fit here.)
3) They simply didn’t think about it - or, if they did, didn’t like the wording. (The vast majority fit this category.)
I think it is fascinating how much of Mormon theology is beginning to creep into the beliefs of many Protestants. When I traveled the rural backroads of OH, PA and WV a few years ago on a regular basis, I often listened to the local religious radio programming (since I didn’t want to hear about the cost of each and every imaginable grain and vegetable), and I would hear some version of a Restored Gospel principle (including Family Home Evening) at least monthly - from ministers who regularly spent time bashing Mormonism openly on air.I loved the irony.
