"I published a portion of a revelation, showing the authority of the First Presidency of the Church, composed at first of Joseph Smith, Sidney Rigdon, and Frederick G. Williams. When this revelation was given, the two last-named brethren were Joseph Smith's counselors, and this First Presidency possessed the power and authority of building up the Kingdom of God upon all the earth, and of setting the Church in order in its perfection. You read in the revelation alluded to that when the Twelve were called and ordained, they possessed the same power and authority as the First Presidents; and in reading further you find that there must needs be appendages and helps growing out of this Priesthood."
"In the setting forth of items of doctrine which pertain to the progress and further building up of the Kingdom of God upon the earth, and the revealing of his mind and will, he has but one mouth through which to make known his will to his people. When the Lord wishes to give a revelation to his people, when he wishes to reveal new items of doctrine to them, or administer chastisement, he will do it through the man whom he has appointed to that office and calling."
