Christ speaks of the weightier matters of the law. Are there weightier matters of the law today? Of course. The scriptures mostly give specifics about the most serious. There is one sin which is unforgivable and it is the worst, the next is murder, and after that the next is adultery.
But we should know by the Holy Ghost as we grow into the gospel which parts of the gospel constitute the weightier matters of the law. Which ones we should have done, and not to leave the others undone.
According to Christ judgment, mercy, and faith are among the weightier matters of the law. That is interesting. We believe in mercy, believe in faith, but we actually believe that judgment is a reproachable evil. Clearly we are passing over one of the the weightier matters of the law ourselves.
When we justify passing over judgment, condemning it instead of developing our ability to judge good from evil, when we put aside our duty to call good good, and to call evil evil, and instead choose to simply call everything good, or try to pretend we can call good good and call evil undecidable, then we are passing over judgment. We have omitted the weightier matters of the law.
When we quote Christ on judgment, why can’t we either quote
Matthew 23:23 Woe unto you, scribes and Pharisees, hypocrites! for ye pay tithe of mint and anise and cummin, and have omitted the weightier matters of the law, judgment, mercy, and faith: these ought ye to have done, and not to leave the other undone.
Luke 11:42 But woe unto you, Pharisees! for ye tithe mint and rue and all manner of herbs, and pass over judgment and the love of God: these ought ye to have done, and not to leave the other undone.
or at least can’t we quote the JST of Matthew 7 which radically clarifies the intention of Christ’s teachings about judging in the sermon on the mount, showing that we are actually commanded to judge righteous judgement, and not to judge unrighteous judgment. Righteous judgement is to judge good as good, and evil as evil, discerning the matter by the light of Christ. Unrighteous judgment, is to judge good to be evil or evil to be good, using some other measure than the light of Christ to judge good from evil.
When we simply call everything good, or refuse to call evil evil, we are not judging by the light of Christ, we are not calling evil evil, and we are judging unrighteous judgement. That is precisely what Christ commanded us not to do. We must not persist in omitting judgment, one of the weightier matters of the law.
We have much of one of the great chapters of scripture, Moroni 7, devoted to teaching us how to judge righteous judgement. It goes into detail teaching how we are to keep the commandment to judge. There we are told that it is given to us to judge, and that by searching diligently in the light of Christ we can learn to judge with the same clarity that we can tell light from darkness.
