“If there ever comes a day when the Saints interfere with the rights of others to live as they see fit, you can know with assurance that the Church is no longer led by a Prophet, but a mere man.”
~Brigham Young (?)~
Verification of this quote does not seem to exist. It does not mean it doesn’t exist, but it is doubtful. Many times Brigham Young actually taught the opposite of this. There was perhaps never a time in LDS history that was darker (or more manipulative) than the Utah years of 1850-1875 as ruled by Brigham Young. The speeches of the prophets and apostles, as well as their actions during those years prove beyond any doubt they were not afraid of interfering with anyone’s life and they were content to enforce the religion on the members and doing their utmost to discourage outsiders in the Utah territory. The role of high Mormon authorities in the Mountain Meadows Massacre is evidence of their desire to keep outsiders from their midst.
There are other occasions where modern church leaders make similar statements to the one attributed to Brigham Young…
“If anyone, regardless of his position in the Church, were to advance a doctrine that is not substantiated by the standard Church works, meaning the Bible, the Book of Mormon, the Doctrine and Covenants, and The Pearl of Great Price, you may know that his statement is merely his private opinion. The only one authorized to bring forth any new doctrine is the President of the Church, who, when he does, will declare it as revelation from God, and it will be so accepted by the Council of the Twelve and sustained by the body of the Church. And if any man speak a doctrine which contradicts what is in the standard Church works, you may know by the same token that it is false and you are not bound to accept it as truth.”
