While reading his diaries, I came across the following from John Pulsipher attesting to the transfiguration of Brigham Young:
After the death of
the Prophet Joseph Sidney Rigdon came and sought to place himself at the head of
the Church. By his platteries deceived many. Just before he called a vote of
the public congregation. Brigham Young the President of the twelve arrived from
his mission -- this was a joyful meeting. The church knew not that Joseph had
ordained Bro. Brigham and the 12 to lead the church -- but they knew that the
twelve was the next quorum in authority. They that served the Lord faithful
were not deceived. I went to meeting where the church met in the grove East of
the Temple where President Young arose and spoke -- and behold he spoke with
the Voice of Joseph -- The very moment I heard him speak I thot of Joseph and
from that time on his voice sounded like Joseph’s and from that time the
church generally were satisfied that the mantle of Joseph was on Brigham. (Diary
of John Pulsipher, Volume 1, p. 12 as found in A Mormon Diary as told by
John Pulsipher (1827-1891), emphasis in bold added)
