Keith Mathison (PostMil):
“Progressive dispensationalists have moved closer to Reformed theology on a number of doctrines. They now acknowledge that the kingdom has been inaugurated and that there is a present as well as a future aspect of the kingdom. They have also recognized the two-peoples-of-God theory to be unbiblical, which, ironically, brings us to the negative side of progressive dispensationalism.
If the defining doctrine of dispensationalism is the two-peoples-of-God theory, then to reject that theory is to reject dispensationalism itself. “Progressive dispensationalism” is therefore both an encouraging trend and a misleading or confusing title.
In view of genuinely positive developments, how problematic is the name “progressive dispensationalism”? Perhaps an illustration will clarify my concern. Suppose I announced that I am a “progressive Baptist.” When asked what that means, I explain that I have rejected believer’s baptism by immersion only. I now believe that infant baptism is biblical and that the mode of baptism should be sprinkling or pouring. But I claim to be a progressive Baptist. What would a good Baptist tell me? He would remind me that believer’s baptism by immersion only is the essence of what it means to be a Baptist.
Similarly, suppose I have become convinced that Jesus will return after the millennium. Would I be honest to describe myself as a “progressive premillennialist.” No. Or what if I have abandoned belief in God? Would I be a progressive theist?
The church suffers too much damage when people do not identify what they really believe. For the sake of accuracy, honesty, and understanding, “progressive dispensationalists” should no longer claim to be dispensational. Traditional dispensationalists would likely concur. Do most dispensational laymen realize that the “dispensationalism” now taught in their seminaries is not the dispensationalism they know? As much as I prefer to see Reformed theology taught in these seminaries, if someone is going to teach nondispensationalism in a dispensational seminary, students and donors should at least be aware of the fact.”
