We come to an extremely important part of Muller, especially in the current theological climate, where much is made of the supposed change in theology and advancement beyond the Westminster standards.
We start by noticing his comment on page 44: “Here we need to ask whether continuities with partristic or medieval models indicate discontinuities with the Reformation or not.” This is a vital question in the whole debate with Rome: who had continuity with the patristics: Rome or the Reformation? Each side claimed continuity. Rome claimed that the Reformation was new. The Reformation claimed that Rome had left the moorings of the early church.
He clarifies the issue even more when he says, “Continuity must not be conceived simplistically as static reproduction, and discontinuity must not be explained, equally simplistically, as change.” Rather the Reformation was “a living tradition which needed to adapt and reformulate its teachings as the historical context demanded…The issue is to examine the course of development, to study the reasons for change, assess the context of each document, and then to make judgments concerning continuity and discontinuity in the light of something more than a facile contrast or juxtaposition.”
He applies this set of definitions against the “Calvin versus the Calvinists school,” although the point goes equally well with ascertaining the continuity of the Reformation with the early church. I disagree most profoundly with those who claim that the Reformation was something new. It was not: it was the rediscovery of old truths, truths that the early church knew, and especially truths that were in the Bible. This is even true with regard to justification, as Thomas Oden’s book The Justification Reader amply demonstrates.
His view of the continuity of Medieval theology with the Reformation is summarized on page 46: “attention will be given to the way in which the presuppositions, enunciated by the orthodox in their prolegomena, carry through into the initial loci of the system, the doctrines of Scripture and God, and through those initial, principial loci, determine the character of the system as a whole.”
In short, I don’t believe that Muller’s view of discontinuity, however much or little there may be between the Reformers and the codifiers, gives any weight to the suppositions of certain modern theologians that we have to go beyond the theology of the Reformation. I don’t believe that the Reformers themselves saw themselves as doing anything new. Rather, certain aspects of the truth which were hidden before (though salvation itself was always known) come into prominence more, as the historical situation changes, and the attacks on orthodoxy shift. Some today confuse this with “progress.” But it is the same old truths, defended against shifting heresies. The drive for something new in theology is at the root of a great deal of the New Perspective on Paul, and the Federal Vision, in my opinion. they are not really interested in defending what was old, tried and true, but rather are interested in throwing out the old, and coming in with changed theology. This is very hurtful to the church.
