The Davenant Institute (the name has just been changed from the Davenant Trust) has a forthcoming book on the subject of Protestant ecclesiology, to which I have contributed an article on the ecclesiology of Pentecost. There are several other superb essays within it that are really worth a read.
The doctrine of the church is often perceived as the weakest link in Protestant theology. These essays argue, on the contrary, that the Reformers’ radical re-thinking of the definition of the church is one of the Reformation’s greatest treasures. Not only is “mere Protestant” ecclesiology firmly in concert with the multifaceted biblical witness, but it is also manifestly in accord with natural reason and the lived experience of Christians throughout the ages. As we celebrate the 500th anniversary of the Reformation, this volume seeks to honor the Protestant heritage by remembering, reclaiming, and critically reflecting upon the relationship between the gospel promise and the community which it calls into being.
