The Lord Gave Joseph Smith the Keys and Declared That Only Joseph Was Authorized to Receive Revelations for the Entire Church
Doctrine and Covenants 28:1–7
1 Behold, I say unto thee, Oliver, that it shall be given unto thee that thou shalt be heard by the church in all things whatsoever thou shalt teach them by the Comforter, concerning the revelations and commandments which I have given.
2 But, behold, verily, verily, I say unto thee, no one shall be appointed to receive commandments and revelations in this church excepting my servant Joseph Smith, Jun., for he receiveth them even as Moses.
3 And thou shalt be obedient unto the things which I shall give unto him, even as Aaron, to declare faithfully the commandments and the revelations, with power and authority unto the church.
4 And if thou art led at any time by the Comforter to speak or teach, or at all times by the way of commandment unto the church, thou mayest do it.
5 But thou shalt not write by way of commandment, but by wisdom;
6 And thou shalt not command him who is at thy head, and at the head of the church;
7 For I have given him the keys of the mysteries, and the revelations which are sealed, until I shall appoint unto them another in his stead.
The Prophet Joseph Smith said:
“. . . It is contrary to the economy of God for any member of the Church, or any one, to receive instructions for those in authority, higher than themselves; therefore you will see the impropriety of giving heed to them; but if any person have a vision or a visitation from a heavenly messenger, it must be for his own benefit and instruction; for the fundamental principles, government, and doctrine of the Church are vested in the keys of the kingdom.”
