“When the work of the Prophet Joseph Smith was completed, when he had received the keys, powers, and ordinances, and had conferred them upon the heads of the Quorum of the Twelve when he realized and sensed that the time had come when he would give his life for his work, he seemed to speak, upon occasion, more emphatically than ever before with regard to the truth of the revelations which he received, indicating that there were those within the Church then who opposed and did not accept all the revelations which God had given through him. These were his words upon the memorable occasion of one of his last addresses to the Saints: ‘Oh! I beseech you go forward and make your calling and election sure – when did I ever teach anything wrong from this stand? When was I ever confounded? I want to triumph in Israel before I depart hence and am no more seen. I never told you I was perfect – but there is no error in the revelations which I have taught’ (12 May 1844).”
