The Servants of Sin Cry Transgression against the Lord’s Chosen Servants
Doctrine and Covenants 121:17
17 But those who cry transgression do it because they are the servants of sin, and are the children of disobedience themselves.
The Prophet Joseph Smith said:
“I will give you one of the Keys of the mysteries of the Kingdom. It is an eternal principle, that has existed with God from all eternity: That man who rises up to condemn others, finding fault with the Church, saying that they are out of the way, while he himself is righteous, then know assuredly, that that man is in the high road to apostasy; and if he does not repent, will apostatize, as God lives.”
(Teachings of Presidents of the Church: Joseph Smith [2007], 318.)
