I have been puzzled that some scriptures command us not to judge and others instruct us that we should judge and even tell us how to do it. I am convinced that these seemingly contradictory directions are consistent when we view them with the perspective of eternity. The key is to understand that there are two kinds of judging: final judgments, which we are forbidden to make; and intermediate judgments, which we are directed to make, but upon righteous principles.
The Savior also commanded individuals to be judges, both of circumstances and of other people.
We must, of course, make judgments every day in the exercise of our moral agency, but we must be careful that our judgments of people are intermediate and not final.
We all need to remember, "Judgment is without mercy to one who has shown no mercy".
Don't envy sinners---have mercy on them. God will destroy them.
...Melancholy and awful that so many are under the condemnation of the devil and going to perdition.... they should be cast out from this Society, yet we should woo them to return to God lest they escape not the damnation of hell!
.. recommend to the Society, to put a double watch over the tongue...hold your tongues about things of no moment---a little tale will set the world on fire.... I do not want to cloak iniquity--all things contrary to the will of God, should be cast from us, but don't do more hurt than good with your tongues--be pure in heart--Jesus designs to save the people out of their sins.
"Fret not thyself because of evil doers" God will see to it.
It is true that we must have appointed judges to deal with the laws of the land and judges in the Church to deal with its members; and they are given the heavy duty and responsibility of judging, which they must not neglect, but they must give righteous judgment according to the law of the land and of the Church.
