Can Mormons be cremated and other ashes put together?
Cremation is permitted but not encouraged. At burial, faithful members are clothed in ceremonial garb as a symbol of their readiness to enter the spirit world. So cremation puts a bit of a hiccup in that rite. Wherever possible, they should be cremated while wearing the ceremonial garb.
