I think those who decry current theological work suffer from a sort of Immediacy Syndrome, without an awareness of how we got our theology, and what that means for the on-going ways theology will develop in our lifetime and well beyond. I mean by this that they imagine that their theology is a once-for-all-time message that needs protected for theological purity; a beleaguered set of doctrines that has been attacked throughout the centuries and has been successfully defended and still must be. Or, in the case of some of our New Calvinism friends, they imagine Christian theology was one certain accumulation of doctrines that was somehow lost in the early days of the church, re-surfaced when John Calvin came along in France, and now must be protected for all time, the one true expression of The Faith; and if you aren’t sure what it is, just keep your John MacArthur and John Piper books handy.
This, of course, suffers from the fact that it is simply historically untrue. All of our theologies have been through numerous revisions. All Christian theology, including Calvin’s, have accumulated, morphed, jettisoned, adjusted, re-vised and edited themselves over and over again. When people, like the emergents, start writing new directions in theology, they are simply repeating a process that has been going on for 20 centuries. (And one that we know, from the diversity of Second Temple Judaism, was going on in Judaism during Jesus’ time as well). Friends of mine who de-cry the emergent/postmodern Christians seem to imagine that whatever they write today might de-rail the Christian faith for all time. I think of that as a sort of Immediacy Syndrome, without a long view of history. What the historical process shows us is that, rather than crying heretic! every time somebody tries to do some work, if we sit back and let the pot simmer on the stove, it allows for the on-going work of Christian theology to develop, just like it always has. It takes a while for new iterations of Christian theology and practice to work its way out. We don’t need to rush it or stress.
