From Dave Black Online:

Thanks so much, Eric, for raising again the perennial question about the Reformers’ insistence on maintaining medieval ecclesiology. I attribute today’s neo-sacralism directly to the Reformers and their faulty theology of the church, against which the Anabaptists inveighed. Under the tutelage of such sacralism church leaders today continue to accommodate biblical Christianity to the Constantinian distortion. Not least is this seen in the return to medieval theology in which “the Son of Man goes forth to war, a kingdom to subdue.” I continue to maintain that the Anabaptists were not indebted to the Reformers, were indeed not even a part of them. I spend a whole chapter in The Jesus Paradigm on this subject mostly because missions cannot thrive in a climate of sacralism. The Anabaptists were oblivious to national borders, and so am I. The New Testament plainly teaches that every Christian is a fulltime minister of the Lord Jesus Christ, a missionary even, and that every true believer will experience something of the cross. To this day there is a hesitation, even on the part of Christians who plainly acknowledge a debt to the Anabaptists, to import biblical ecclesiology into their churches. I say shame on us. We should know better.
