A solemn assembly, as the name implies, denotes a sacred, sober, and reverent occasion when the Saints assemble under the direction of the First Presidency. Solemn assemblies are used for three purposes: the dedication of temples, special instruction to priesthood leaders, and sustaining a new President of the Church. This conference session today is a solemn assembly for the purpose of sustaining a newly called Church President and other officers of the Church.
There is a pattern to solemn assemblies that distinguishes them from other general Church meetings where we sustain officers of the Church. That pattern, which was established by the Prophet Joseph Smith, is that the priesthood quorums, commencing with the First Presidency, stand and manifest by the uplifted right hand their willingness to sustain the President of the Church as a prophet, seer, and revelator, and uphold him by their confidence, faith, and prayers. The priesthood quorums of the Church so manifest by their vote. Then the general body of all the Saints stand and signify their willingness to do the same. The other leaders of the Church are similarly sustained in their offices and callings.
When we sustain the President of the Church by our uplifted hand, it not only signifies that we acknowledge before God that he is the rightful possessor of all the priesthood keys; it also means that we covenant with God that we will abide by the direction and the counsel that come through His prophet. It is a solemn covenant. ~ David B Haight - 1994
"Nothing opens the heavens quite like the combination of increased purity, exact obedience, earnest seeking, daily feasting on the words of Christ in the Book of Mormon, and regular time committed to temple and family history work." ~ President Russell M. Nelson
