This thread also illustrates the limits of calling Reformed theology "Calvinism." Muller and others are probably right when they say that we should stop using this modifier. . .
Strictly speak, no dispensationalist can be a "Calvinist."
Dispensationalism, in all forms, is utterly contrary to the faith and the system of doctrine confessed by the Reformed churches in their confessional documents. . .
The fact is, the term "Calvinism" is often used as a synonym for TULIP and limited to those soteriological points. You say this is wrong. I agree. But that doesn't really change things. Nor do I believe a few books on the subject will change the common notion outside confessional Reformed folk.
Hence, we are stuck with prefatory comments like "True Calvinism is broader than the five points", etc. And the purpose is what? To ask someone (like a dispensationalist) to quit referring to himself as a Calvinist? How's that working out?
The "lofty" Reformed may bristle at the term "Calvinist", but the word has meaning in the vernacular. Calvinism does not equal Reformed anymore than a thunder cloud equals an ocean. Call it what you will - Calvinism, or the doctrines of sovereign grace, it's a far cry from Armianism and semi-Pelagianism. For many, it's a starting point into the Reformed faith. We should encourage this first step among many who have been steeped in Finneyism.
