Verse 14 nullifies that view. It's clear he's talking about someone who only claims to believe.
That would an opinion only. Nothing to indicate that someone is "only claiming" to believe. Everything to indicate he was talking about believers who aren't demonstrating their faith. By not demonstrating one's faith means it isn't "active". Therefore the figurative language of a "dead faith".
Or do you think the answer to his rhetorical question is "yes"?
No. The Answer is clearly "no". But James wasn't speaking of eternal salvation, as you presume.
When he begins v.14 with the question, "what good is it?", he wasn't speaking in the sense of eternal salvation, but good for rescuing or delivering the believer from something. That is the issue. He doesn't spell out what the believer needs to be rescued or delivered from, but from the context, it is quite clear (v.15,16) that the charge of hypocrisy is in view. When believers behave as v.15 and 16 illustrate, they are being quite hypocritical. So, believers who don't demonstrate their faith are hypocrites. Not that they aren't saved.
The issue in Scripture is belief. What is believed. Given all the admonitions in Scripture for obedience, it is clear that believers may not produce works.
Otherwise, all the admonitions are meaningless.
That really has nothing to do with the OP.
Sure. Ignore the issue. And the admonitions HAVE EVERYTHING to do with Christian living, which is the point of the book of James. Practical Christian living.
From my Rainbow Study Bible on the content of James:
"To merely say we have faith is insufficient. (unfortunately, there no clarity as to being "insufficient" for) James stresses that we must have faith that manifests itself in the action of good deeds. (as v.15,16,18 clearly indicate). His letter covers a wide range of sins: pride, prejudice, HYPOCRISY, worldliness, the untamed tongue and apathy. This PRACTICAL TREATISE gives the scattered Jewish Christians a strong understanding of their union in Christ."
Now, I've exegeted much of James 2, and all you've done is disagree, with no explanation or exegesis at all. And you've not even attempted to refute my points.
There is no support for your view, regardless of how many confused believers agree with it.
The fact that James is a practical treatise shows that he was not concerned about the Jewish believers' salvation, but their lifestyle, and to avoid such sins as pride, prejudice, hypocrisy, worldliness, an untamed tongue, and apathy.
Practical Christian living has nothing to do with getting saved. It's about what should happen after we get saved.
btw, simply quoting back 2:14-17 isn't a refutation. You've dismissed 2:16 entirely, and without reason. And 2:18 is James' point in a nutshell. The question is how can a believer show their faith apart from works. It can't be done, is James' point.
