It is commonplace to observe that the history of thought reveals certain recurring patterns whose mode of expression changes according to context. It is equally apparent that to chart the salient characteristics of an influential way of thinking – to give concrete, clearly defined shape to the usually tangled fundamental impulses informing a cast of mind – is a complex, difficult task which calls for attention from (at least) the historian, the psychologist, the philosopher and, in the case of religious figures and movements, the theologian alike. With regard to the manner of thinking embodied in the theological doctrines of Martin Luther such a task is fraught with more than the usual number of pitfalls. In the first place, following recent Luther scholarship, we must be wary of assuming that the great Reformer held fast to a single set of theological opinions throughout his long career. We shall not, therefore, attempt to reach conclusions applicable to Luther's thought as a whole, but rather shall focus exclusively on a number of key early expositions of the Theologia Crucis. Here, between about 1514 and 1520, we find, according to our argument, enough thematic unity to warrant the search for underlying principles. A second, less easily disposed of difficulty is the lack of a working consensus as to how and with what aims in mind one should even begin an historical analysis of Luther's texts. For example, to the believer who regards Luther's basic tenets as in a straightforward sense divinely inspired, the attempt to extract from his writings the ingredients of a certain thoroughly human way of thinking will seem doomed to inadequacy from the start. Likewise, for different reasons, many of today's.
