Fifty years ago in April 1967, David Oman McKay (1873-1970), the ninth president of the LDS Church, gave a talk in the priesthood session of General Conference that was unique. It was entitled "Consciousness of God: Supreme Goal of Life."
How should we regard the Godhead, or the Trinity as many Christians call it, taking into consideration biological evolution, particularly human evolution, and other modern science?
I perceive that priesthood was originally an inner experience of Divine Power and Presence in humans, a deep Realization when they subdued their egoic psychological "natural man" self in consciousness, and perceived their real Being underneath it in Glory, beyond words. I believe humans eventually organized this mystical experience, and the knowledge of it, instituting it into the "ordination" to an "office" of "priesthood," meant to indicate those who had direct experience of God.
An addition to the BHT, about the problems with religious authorities.
President Joseph Fielding Smith, as President of the Quorum of the Twelve Apostles who later became the tenth President and "Prophet, Seer, and Revelator" of the LDS Church, wrote the following that was published in 1954: "IF EVOLUTION IS TRUE, THE CHURCH IS FALSE."
