"President Joseph then asked the conference if they were satisfied with the First Presidency, so far as he was concerned as an individual to preside over the whole Church, or would they have another? If, said he, I have done anything to injure my character, reputation, or standing, or have dishonored our religion by any means in the sight of angels or in the sight of men and women, I am sorry for it; and if you will forgive me, I will endeavor to do so no more....
"Motion was made are seconded, that President Joseph Smith continue President of the whole Church. After a few minutes' silence, the motion was put by President Brigham Young, when one vast sea of hands was presented, and the motion was carried unanimously. President Joseph returned his thanks to the assembly for the manifestation of their confidence, and said he would serve them according to the best ability God should give him." (Joseph Smith, HC 5:17)
"And all things shall be done by common consent in the church, by much prayer and faith, for all things you shall receive by faith. Amen." (D&C 26:2)
"For all things must be done in order, and by common consent in the church, by the prayer of faith." (D&C 28:13)
"Perhaps it may make some of you stumble, were I to ask you a question—Does a man's being a Prophet in this Church prove that he shall be the President of it? I answer, no! A man may be a Prophet, Seer, and Revelator, and it may have nothing to do with his being the President of the Church. Suffice it to say, that Joseph was the President of the Church, as long as he lived: the people chose to have it so. He always filled that responsible station, by the voice of the people. Can you find any revelation appointing him the President of the Church? The keys of the Priesthood were committed to Joseph, to build up the Kingdom of God on the earth, and were not to be taken from him in time or in eternity; but when he was called to preside over the Church, it was by the voice of the people; though he held the keys of the Priesthood, independent of their voice." (Brigham Young, JD 1:133)
