“As a General Authority, it is my responsibility to preach general principles. When I do, I don’t try to define all the exceptions. 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 the general rules. Whether an exception applies to you is your responsibility. You must work that out individually between you and the Lord.
“The Prophet Joseph Smith taught this same thing in another way. When he was asked how he governed such a diverse group of Saints, he said, “I teach them correct principles, and they govern themselves” (in John Taylor, “The Organization of the Church,” Millennial Star, Nov. 15, 1851, 339). In what I have just said, I am simply teaching correct principles and inviting each one of you to act upon these principles by governing yourself.” (The Dedication of a Lifetime)
“Teachers who are commanded to teach “the principles of [the] gospel” and “the doctrine of the kingdom” (D&C 88:77) should generally forgo teaching specific rules or applications. For example, they would not teach any rules for determining what is a full tithing, and they would not provide a list of dos and don’ts for keeping the Sabbath day holy. Once a teacher has taught the doctrine and the associated principles from the scriptures and the living prophets, such specific applications or rules are generally the responsibility of individuals and families.
“Well-taught doctrines and principles have a more powerful influence on behavior than rules. When we teach gospel doctrine and principles, we can qualify for the witness and guidance of the Spirit to reinforce our teaching, and we enlist the faith of our students in seeking the guidance of that same Spirit in applying those teachings in their personal lives.” (Gospel Teaching)
