In the summer of 1830, while The Church of Jesus Christ of Latter-day Saints was yet in its infancy, Oliver Cowdery, “the second elder of [the] church” (D&C 20:3), wrote Joseph Smith, saying, “I command you in the name of God to erase those words, that no priestcraft be amongst us.” Oliver Cowdery was referring to words Joseph Smith added to Doctrine and Covenants 20:37. Oliver disapproved of a phrase included in the list of requirements for baptism: “And truly manifest by their works that they have received of the Spirit of Christ unto the remission of their sins.”
Joseph, the Prophet, was astonished and saddened. He knew that this baptismal requirement had come by revelation from the Lord. Joseph “immediately wrote to [Oliver] in reply, in which [Joseph] asked him by what authority [Oliver,] took upon him to command [him] to alter or erase…a revelation…from Almighty God.”
