“Seek the Spirit of the Lord”, Ensign, Apr. 1988, pg. 5; “Several years after Joseph Smith was martyred, he appeared to President Brigham Young. Hear his message:” ‘Tell the people to be humble and faithful, and be sure to keep the spirit of the Lord and it will lead them right. Be careful and not turn away the small still voice; it will teach you what to do and where to go; it will yield the fruits of the kingdom. Tell the brethren to keep their hearts open to conviction, so that when the Holy Ghost comes to them, their hearts will be ready to receive it.’ (Manuscript History of Brigham Young, 23 Feb. 1847, 2 vols., ed. Elden Jay Watson, Salt Lake City: Elden J. Watson, 1968, 1971, 2:529.)”The Lord has prospered this work and will continue to do so. He is close to His servants, even within whispering distance.”This latter-day work is spiritual. It takes spirituality to comprehend it, to love it, and to discern it. Therefore, seek the Spirit in all you do. Keep it with you continually. That is our challenge.”I pray that the Spirit of the Lord will be with each of you in your homes and families.” – Ezra Taft Benson
Isaiah 8:19-20; “And when they shall say unto you, Seek unto them that have familiar spirits, and unto wizards that peep, and that mutter: should not a people seek unto their God? for the living to the dead? 20 To the law and to the testimony: if they speak not according to this word, it is because there is no light in them.”
Apparently more than one of their leaders believed this and continue to do so. You cannot talk to dead people!
