You said I made up a second meaning of 'justified'.
I showed you I did not.
Well, as I've shown in post #135,354 above it comes in handy for determining if you get to stay in the church or whether we should turn you over to satan and have nothing to do with you.
Claiming to be a brother don't cut it. How you act, that's what shows if you're a true believer or not:
"11But now I am writing you not to associate with anyone who claims to be a brother but is sexually immoral or greedy, an idolater or a verbal abuser, a drunkard or a swindler. With such a man do not even eat." - 1 Corinthians 5:11
We are commanded to show 'faith alone' people (as James means that) the door.
As far as your 'twelve tribes' doctrine, we know James is not talking about being
made righteous by works because it's impossible to be justified by works. How many works does it take to be justified by works? You know the answer (at least you should). ALL OF THEM:
"10For whosoever shall keep the whole law, and yet offend in one point, he is guilty of all." - James 2:10
No one can be justified by works because no one can do all right things all the time. Justification (being made righteous) has NEVER been by works and NEVER will be. It's impossible for anybody, Jew or gentile, to do.
