We have this counsel from Ezra Taft Benson:
President Marion G. Romney tells of this incident, which happened to him:
I remember years ago when I was a Bishop I had President [Heber J.] Grant talk to our ward. After the meeting I drove him home....Standing by me, he put his arm over my shoulder and said: "My boy, you always keep your eye on the President of the Church, and if he ever tells you to do anything, and it is wrong, and you do it, the Lord will bless you for it." Then with a twinkle in his eye, he said, "But you don't need to worry. The Lord will never let his mouthpiece lead the people astray." [In Conference Report, October 1), p. 78]
This has been extended to local priesthood leaders. I've personally been counseled many times to follow the priesthood line of authority, even if it seems wrong to me personally. And if it is wrong, I'll be blessed for it.
Most organizations have an ombudsman or even a "hotline" for reporting abuse within the system. Not so the LDS church. And we all know what happened to Lavina Anderson when she tried to change this.
