Individual Exceptions Are between Each Person and the Lord

“There are exceptions to some rules. For example, we believe the commandment is not violated by killing pursuant to a lawful order in an armed conflict. But don’t ask me to give an opinion on your exception. I only teach general rules. Whether an exception applies to you is your responsibility. You must work that out individually between you and the Lord.” 

- Dallin H. Oaks, Ensign, June 2006, p. 16
