No office is required to receive the fullness of the priesthood

Joseph Fielding Smith:

“I do not care what office you hold in the Church — you may be an apostle, you may be a patriarch, a high priest, or anything else — but you cannot receive the fullness of the priesthood and the fullness of eternal reward unless you receive the ordinances of the house of the Lord; and when you receive these ordinances, the door is then open so you can obtain all the blessings which any man can gain.

Do not think because someone has a higher office in the Church than you have that you are barred from receiving the fullness of the Lord’s blessings. You can have them sealed upon you as an elder, if you are faithful; and when you receive them, and live faithfully and keep these covenants, you then have all that any man [or woman] can get.” – Joseph Fielding Smith (Conference Report, April 1970, p. 59)
