Sustaining Church Leaders

Teachings of Presidents of the Church: George Albert Smith(2011), 64; emphasis added. This quotation came from a conference address by Elder George Albert Smith in 1919. He became President of the Church in 1945
“The obligation that we make when we raise our hands … is a most sacred one. It does not mean that we will go quietly on our way and be willing that the prophet of the Lord shall direct this work, but it means … that we will stand behind him; we will pray for him; we will defend his good name, and we will strive to carry out his instructions as the Lord shall direct.”

Common Consent

Russell M Nelson, Sustaining the Prophets, October 2014 General Conference
"When we sustain prophets and other leaders, we invoke the law of common consent..."
...
“All leaders in the Lord’s Church are called by proper authority. No prophet or any other leader in this Church, for that matter, has ever called himself or herself. No prophet has ever been elected. The Lord made that clear when He said, “Ye have not chosen me, but I have chosen you, and ordained you.”10 You and I do not “vote” on Church leaders at any level. We do, though, have the privilege of sustaining them.”

Doctrine and Covenants 42:11

11 Again I say unto you, that it shall not be given to any one to go forth to preach my gospel, or to build up my church, except he be ordained by some one who has authority, and it is known to the church that he has authority and has been regularly ordained by the heads of the church.
