There was a deacon in the Church some years ago who observed one family member abusing another family member. He commanded the abuser to repent and cited his Aaronic priesthood as authority for the order. The abuser declined to acquiesce to his request.
Question: What lesson should the deacon have learned from this?
Consider the account of the two prophets in JST 1 Kings 13.
Question: What lesson should we take from the example of the prophet from Judah?
Question: For what purposes do people cite authority for their words or actions?
Question: Which of those purposes pass the Golden Rule test?
Question: What exercises of power or authority are compatible with the Golden Rule?
Question: What is the power of God?
Question: What is the authority of God?
Question: What is the significance of a commandment from God?
D&C 121, as well as Jesus’s teachings to his disciples about authority and power, are good places to start on these things. (Handy keywords to search Jesus’s teachings for: rabbi, master, benefactors, greatest, servant, younger)
My answers will probably be different than yours, but that doesn’t necessarily make me “right” and you “wrong.”
