I'll pardon you at your request. Calvinists are Christians. That you say they've never claimed themselves Christian is unfortunate.
Clearly I said just as you've said that faith doesn't save, or that "just faith" cannot save alone. But at the same time you present Scriptures seeming to present that faith does save. You seem to be thoroughly confused, and tend to attempt to embrace both sides at the same time. I take it that you are deficient in your understanding while making pretense to understand whist playing both sides of the fence.
So you're saying Calvinist brethren are not Christian? I said "Calvinist = Christian" and you disagree that Calvinists are Christian? Yes? No?
Faith has never saved anyone. Grace? Yes, that is whereby and wherewithal all are saved. Faith is merely a byproduct of grace.
