In other words: "You've presented arguments that make sense and are well-supported that are in conflict with my theology, so I will leave this conversation."
Not what he is saying. He is saying impasse. His theology is that James and Paul are not the same. Glory has said that she used to be Mid Acts. I'd reckon the blending of James' message and Paul's is at odds. For me, it is clear that Paul and James would argue. Perhaps another has the need to say "All is the Word of God" in scripture hence "Lordship Salvation" works in salvation etc. Why? Because James says faith without works is dead. For me, I have to at least entertain a viability between Paul and James: James was talking to Jews. Paul to gentiles. What does it mean? It means Jews still had to keep the Law. I don't know if they still do today. Thus, though there is no longer Greek or Jew, there is a difference in their Faith (not salvation I'd reckon).
Jas 1:1 James, a servant of God and of the Lord Jesus Christ,
to the twelve tribes in the Dispersion, greeting
Jas 2:14 My brothers, what profit is it if a man says he has faith and does not have works?
Can faith save him?
Jas 2:21 Was not Abraham our father
justified by works when he had offered Isaac his son upon the altar?
Compare with the Apostle Paul:
Eph 2:8 For by grace you are saved through faith, and that not of yourselves, it is the gift of God,
Eph 2:9
not of works, lest anyone should boast.
Eph 2:10 For we are His workmanship,
created in Christ Jesus to good works, which God has before ordained
that we should walk in them.
For the gentile, God ordained (prepared) for us to do as the Spirit guides.
It'd seem we as gentiles have more to our grace. God does even this work for us, but it seems evident that Jews had to toe the line, likely because they were entrusted with it and all their promises weren't just spiritual. IOW, there is a conflation of necessity Jews have (or at least had) to them keeping the Law.
Is anything applicable to a gentile in James?
One consideration:
Jas 5:13 Is any among you afflicted? Let him pray. Is any cheerful? Let him sing psalms.
Jas 5:14 Is any sick among you? Let him call for the elders of the church, and let them pray over him, anointing him with oil in the name of the Lord.
Jas 5:15 And the prayer of faith will cure the sick, and the Lord shall raise him up. And if he has committed sins, it will be forgiven him.
Jas 5:16 Confess faults to one another, and pray for one another, that you may be healed. The effectual fervent prayer of a righteous one avails much.
I believe this applicable to all of us. We heal by bringing all our cares before the Lord. Thus, as we read James, we see what must be different and also appreciate what can or does apply across board. For your (pl) inspection. -Lon
