I don't mind at all. That is why I included the link - except to the last one, which since it is included with your scriptures didn't seem necessary.
I don't know if you and Moodshadow are looking for statements that include the part about the thinking having already been done, or just the idea of following the prophet because he will not or cannot lead the church astray. I'm not trying to prove anything by finding these. As much as non-LDS Christians are accused on this board of saying that LDS blindly follow the prophet, or that they are brainwashed, I haven't claimed either. I also haven't ever been LDS. Moodshadow had commented how she had a hard time finding statements, so I offered them in case they helped.
I get the feeling that you think that I was trying to take these statements out of context. I was not, which was why I provided the links so that anyone could read the entire talk if they wished to do so. There are other similar statments that have been made, but I had thought that these were sufficient. Here are several more if that helps.
President Harold B. Lee, referring to President David O. McKay, said:
We believe in a living prophet, seer, and revelator, and I bear you my solemn witness that we have a living prophet, seer, and revelator. We are not dependent only upon the revelations given in the past as contained in our standard worksas wonderful as they arebut
we have a mouthpiece to whom God does and is revealing his mind and will. God will never permit him to lead us astray. As has been said, God would remove us out of our place if we should attempt to do it. You have no concern. Let the management and government of God, then, be with the Lord. Do not try to find fault with the management and affairs that pertain to him alone and by revelation through his prophethis living prophet, his seer, and his revelator (The Place of the Living Prophet, Seer, and Revelator [address delivered to seminary and institute faculty, Brigham Young University, 8 July 1968], p. 13).
President Joseph Fielding Smith explained:
I think there is one thing which we should have exceedingly clear in our minds. Neither the President of the Church, nor the First Presidency, nor the united voice of the First Presidency and the Twelve will ever lead the Saints astray or send forth counsel to the world that is contrary to the mind and will of the Lord (in Conference Report, Apr. 1972, p. 99; or Ensign, July 1972, p. 88).
