I think you need to brush up on your Bible a little bit, there is only one Judge and it is certainly not you... mes 4:11-12 “Speak not evil one of another, brethren. He that speaketh evil of his brother, and judgeth his brother, speaketh evil of the law, and judgeth the law: but if thou judge the law, thou art not a doer of the law, but a judge.
I think you need a complete re-read of the book of James & the rest of the New Testament! First of all, Jesus Himself referenced the legalists of His day -- the Pharisees -- as anything but children of God (called them children of Satan in the latter part of John 8) ... Jesus hardly referenced legalists as His "brother"...
In the New Testament, "brother" is either a reference to a "flesh and blood" brother or a fellow church fellowship brother -- NOT to every cultist/occultist under the sun! And since you cite a verse using the "one...another" language, the few dozen "one another" references in the New Testament apply to Christians,/I> and how they treat fellow Christians.
The book of James isn't some "handbook" for ethics for the population-at-large...'twas written to Jewish Christians:
"To the twelve tribes scattered among the nations: Greetings. 2 Consider it pure joy, my brothers and sisters, whenever you face trials of many kinds, 3 because you know that the testing of your faith produces perseverance." (James 1). [It'd be ludicrous for say, a polytheist or pagan to be receiving "faith" counsel and to "consider it pure joy" about trials]
Hence, these are references to Christians how they are to treat fellow Christians...it's not a legalistic "thou shalt" on how Christians were to address either polytheists or legalists -- of which Mormons are both.
For that, you can go to passages like Jude 3 and 2 Cor. 10:3-5. Jude says we are to contend for the faith ONCE delivered to the saints; and Paul says we are to bring down strongholds, pretensions, and arguments that raise themselves up vs. the knowledge of God.
If you think counterfeits should stay as is, be sure to call your Congressmen and tell them to stop all govt funding to stop counterfeiters and identity thieves out there. What's done financially is certainly done spiritually.
