When speaking of Baur's contribution to New Testament criticism, we alluded to his historical works. He was in a distinct sense a reformer of the method of the writing of church history. To us the notions of the historical and of that which is genetic are identical. Of course, naïve religious chronicles do not meet that test. A glance at the histories produced by the age of rationalism will show that these also fall short of it. The perception of the relativity of institutions like the papacy is here wholly wanting. Men and things are brought summarily to the bar of the wisdom of the author's year of grace. They are approved or condemned by this criterion. For Baur, all things had come to pass in the process of the great life of the world. There must have been a rationale of their becoming. It is for the historian with sympathy and imagination to find out what their inherent reason was. One other thing distinguishes Baur as church historian from his predecessors. He realised that before one can delineate one must investigate. One must go to the sources. One must estimate the value of those sources. One must have ground in the sources for every judgment. Baur was himself a great investigator. Yet the movement for the investigation of the sources of biblical and ecclesiastical history which his generation initialed has gone on to such achievements that, in some respects, we can but view the foundations of Baur's own work as precarious, the results at which he arrived as unwarranted. New documents have come to light since his day. Forgeries have been proved to be such, The whole state of learning as to the literature of the Christian origins has been vastly changed. There is still another other thing to say concerning Baur. He was a Hegelian. He has the disposition always to interpret the movements of the religious spirit in the sense of philosophical ideas. He frankly says that without speculation every historical investigation remains but a play upon the surface of things. Baur's fault was that in his search for, or rather in his confident discovery of, the great connecting forces of history, the biographical element, the significance of personality, threatened altogether to disappear. The force in the history was the absolute, the immanent divine will. The method everywhere was that of advance by contrasts and antagonisms. One gets an impression, for example, that the Nicene dogma became what it did by the might of the idea, that it could not by any possibility have had any other issue.
