First, a righteous judgment must, by definition, be intermediate. It will refrain from declaring that a person has been assured of exaltation or from dismissing a person as being irrevocably bound for hellfire. It will refrain from declaring that a person has forfeited all opportunity for exaltation or even all opportunity for a useful role in the work of the Lord. The gospel is a gospel of hope, and none of us is authorized to deny the power of the Atonement to bring about a cleansing of individual sins, forgiveness, and a reformation of life on appropriate conditions.
Second, a righteous judgment will be guided by the Spirit of the Lord, not by anger, revenge, jealousy, or self-interest. The Book of Mormon teaches: “For behold, my brethren, it is given unto you to judge, that ye may know good from evil; and the way to judge is as plain … as the daylight is from the dark night.
“For behold, the Spirit of Christ is given to every man, that he may know good from evil” (Moro. 7:15–16).
The Savior taught that one of the missions of the Comforter He would send would be to assist in the judgment of the world by guiding the faithful “into all truth” (John 16:13; see also John 16:8, 11).
Third, to be righteous, an intermediate judgment must be within our stewardship. We should not presume to exercise and act upon judgments that are outside our personal responsibilities. Some time ago I attended an adult Sunday School class in a small town in Utah. The subject was the sacrament, and the class was being taught by the bishop. During class discussion a member asked, “What if you see an unworthy person partaking of the sacrament? What do you do?” The bishop answered, “You do nothing. I may need to do something.” That wise answer illustrates my point about stewardship in judging.
Fourth, we should, if possible, refrain from judging until we have adequate knowledge of the facts. In an essay titled “Sitting in the Seat of Judgment,” the great essayist William George Jordan reminded us that character cannot be judged as dress goods—by viewing a sample yard to represent a whole bolt of cloth (see The Crown of Individuality [1909], 101–5).

The judgements about mormons and mormonism that go on in this section of the forum are evil and certainly not righteous judgements by the catholics.
