If they were married in the temple, I would be a little more hesitant to think he did this. There are sacred covenants made there, and the couple is sealed for time and all eternity. One must adhere to the highest moral standards in order to enter the temple. Not every member of the Church goes there, though it is the ultimate goal for every member. Without divulging certain sacred things, the temple clothing is symbolic of a host of things, including the covenants made therein. Other religious groups also have similar burial practices. Again, they are merely symbolic of the things that take place within the temple and the covenants that are made. Those covenants include adhering to higher moral standards.
