Nevertheless, the labours of another generation of scholars have carried our knowledge of the New Testament literature far beyond the point which it had reached when Strauss first wrote. At that time the dates of but few of the New Testament writings had been fixed with any approach to certainty; the age and character of the fourth gospel, the genuineness of the Pauline epistles, even the mutual relations of the three synoptics, were still undetermined; and, as a natural result of this uncertainty, the progress of dogma during the first century was ill understood. At the present day it is impossible to read the early work of Strauss without being impressed with the necessity of obtaining positive data as to the origin and dogmatic character of the New Testament writings, before attempting to reach any conclusions as to the probable career of Jesus. These positive data we owe to the genius and diligence of the Tubingen School, and, above all, to its founder, Ferdinand Christian Baur. Beginning with the epistles of Paul, of which he distinguished four as genuine, Baur gradually worked his way through the entire New Testament collection, detecting--with that inspired insight which only unflinching diligence can impart to original genius--the age at which each book was written, and the circumstances which called it forth. To give any account of Baur's detailed conclusions, or of the method by which he reached them, would require a volume. They are very scantily presented in Mr. Mackay's work on the "Tubingen School and its Antecedents," to which we may refer the reader desirous of further information. We can here merely say that twenty years of energetic controversy have only served to establish most of Baur's leading conclusions more firmly than ever. The priority of the so-called gospel of Matthew, the Pauline purpose of "Luke," the second in date of our gospels, the derivative and second-hand character of "Mark," and the unapostolic origin of the fourth gospel, are points which may for the future be regarded as wellnigh established by circumstantial evidence. So with respect to the pseudo-Pauline epistles, Baur's work was done so thoroughly that the only question still left open for much discussion is that concerning the date and authorship of the first and second "Thessalonians,"--a point of quite inferior importance, so far as our present subject is concerned. Seldom have such vast results been achieved by the labour of a single scholar. Seldom has any historical critic possessed such a combination of analytic and of co-ordinating powers as Baur. His keen criticism and his wonderful flashes of insight exercise upon the reader a truly poetic effect like that which is felt in contemplating the marvels of physical discovery.
