In these words Baur has accurately described the main defect of Strauss’s book. When Strauss drew from the discrepancies and contradictions of the various narratives of the Gospels the conclusion that they have all alike little credibility, the conclusion was intelligible enough in reply to the ingenious artifices of the traditional harmonists, who maintained that in spite of the contradictions the evangelists were all alike worthy of credit; but really this line of procedure on the part of Strauss conformed as little as that of the harmonists to the principles of strict historical inquiry. These principles require us to examine the relative value of the various sources with reference to their age, to the situation, the character, the interests, and aims of their author; to assign accordingly to one account a higher measure of credibility than to another; and so, by distinguishing between what is better and what is not so well attested, to make out what is probable and reach the original matter of fact. It is true Strauss made some advance towards such a differentiation of the relative value of the gospel narratives; and particularly with reference to the inferior historical value of the Johannine in comparison with the Synoptic narrative, he has made acute observations, the worth of which ought to be estimated the higher as they boldly opposed the then dominant preference for the Gospel of John, and effectively prepared the way for the criticism of Baur. But it was not Strauss’s forte to prepare, as the foundation of the material critique of the gospel history, a thorough critique of the literary sources, nor, in the state of the general science of criticism at the time, could this be very well expected. When all deductions have been made, to Strauss belongs the honour of having given, by his criticism of the gospel narratives, the most effective impulse to a more penetrating examination of the sources of the gospel story, and of having prepared the way for this to no small extent, particularly as regards the Fourth Gospel. Baur’s classical critique of this Gospel completed in this direction the criticism of Strauss, and laid its foundations deeper. As regards the Synoptic Gospels, Weisse and Ewald, Holtzmann and Volkmar, did good work towards clearing up the relations of the Gospels to each other, especially in establishing the priority of Mark, by which a firmer basis was laid for the positive decision of the question as to the historical foundations of the gospel tradition. The fruit of this critique of the sources, carried on from various sides with painstaking industry, was the new literature dealing with the life of Jesus, which, just a generation after the first Leben Jesu of Strauss, took up again the problems it had raised, but in a new fashion, and with improved critical apparatus. We shall have further on to refer to Strauss’s new life of Jesus.
