It is not alone sufficient for us as Latter-day Saints to follow our leaders and to accept their counsel, but we have the greater obligation to gain for ourselves the unshakable testimony of the divine appointment of these men and the witness that what they have told us is the will of our Heavenly Father.
President Harold B. Lee, General Conference, October 1950
Some members assume that one can be in full harmony with the spirit of the gospel, enjoy full fellowship in the Church, and at the same time be out of harmony with the leaders of the Church and the counsel and direction they give. Such a position is wholly inconsistent, because the guidance of the Church comes not alone from the written word but also from continuous revelation, and the Lord gives that revelation to the Church through his chosen prophet. It follows, therefore, that those who profess to accept the Gospel and who at the same time criticize and refuse to follow the counsel of the Prophet are assuming an indefensible position. Such a spirit leads to apostasy.
President Marion G. Romney, April 1983 General Conference
