I wrote a paper on what keys are. I discuss every reference to keys in the scriptures and in the speeches of Joseph Smith, and some quotes from contemporary authors. This paper also deals with the Mormon succession crisis, and who, if anybody, has inherited the right to run the modern corporation. Power in the Priesthood.
This paper presents an analysis of Adam-God, sometimes called “doctrine”, sometimes called a “mystery”, sometimes called “a theory”, sometimes renounced or condemned as “false doctrine”. Strictly speaking, the Hebrew word Adam means “man”, and we know from the teachings of Joseph Smith, and if we could search deeply within ourselves, we would know that we (as “man” or humankind) have our roots in God, will eventually return to God, and we are manifestation of God in this world. The problem is if we try to do what Brigham did: whenever we find the word “God” anywhere in the Gospel, substitute “Adam”, the name for that specific personality, the husband of Eve, the first flesh upon the earth, in place of the God we worship, and the God which we are trying to become like, we run into a lot of difficulties reconciling the two. Brigham Young saw some of those difficulties and fabricated unsupported, unscriptural, and downright false doctrine on the fly in order to justify his conclusions. The result was a doctrinal disaster and an embarrassment to the church. The church gradually retreated from this doctrine, but the core implications of this doctrine remain and continue to haunt the church today. https://john144restoration.files.wordpress.com/2022/04/adam-god-theory-or-doctrine.pdf
