letters of Paul, for example, are written in palpable advocacy of opinions which were bitterly opposed by other apostles. The biographies of Jesus suggest that they also represent, the one this tendency, the other that. We have no cause to assert that this trait of which we speak implies conscious distortion of the facts which the author would relate. The simple-minded are generally those least aware of the bias in the working of their own minds. It is obvious that until we have reckoned with such elements as these, we cannot truly judge of that which the Gospels say. To the elaboration of the principles of this historical criticism Baur gave the labour of his life. His biblical work alone would have been epoch-making. Ferdinand Christian Baur was born in 1793 in Schmieden, near Stuttgart. He became a professor in Tübingen in 1826 and died there in 1860. He was an ardent disciple of Hegel. His greatest work was surely in the field of the history of dogma. His works, _Die Christliche Lehre von der Vereöhnung_, 1838, _Die Christliche Lehre von der Dreieinigkeit und Menschwerdung Gottes_, 1841-1843, his _Lehrbuch der Christlichen Dogmengeschichte_, 1847, together constitute a contribution to which Harnack's work in our own time alone furnishes a parallel. Baur had begun his thorough biblical studies before the publication of Strauss' book. The direction of those studies was more than ever confirmed by his insight of the shortcomings of Strauss' work. Very characteristically also he had begun his investigations, not at the most difficult point, that of the Gospels, as Strauss had done, but at the easiest point, the Epistles of Paul. As early as 1831 he had published a tractate, _Die Christus-Partei in der Corinthischen Gemeinde_. In that book he had delineated the bitter contest between Paul and the Judaising element in the Apostolic Church which opposed Paul whithersoever he went. In 1835 his disquisition, _Die sogenannten Pastoral-Briefe_, appeared. In the teachings of these letters he discovered the antithesis to the gnostic heresies of the second century. He thought also that the stage of organisation of the Church which they imply, accorded better with this supposition than with that of their apostolic authorship. The same general theme is treated in a much larger way in Baur's _Paulus, der Apostel Jesu Christi_, in 1845. Here the results of his study of the book of the Acts are combined with those of his inquiries as to the Pauline Epistles. In the history of the apostolic age men had been accustomed to see the evidence only of peace and harmony. Baur sought to show that the period had been one of fierce struggle, between the narrow Judaic and legalistic form of faith in the Messiah and that conception, introduced by Paul, of a world-religion free from the law. Out of this conflict, which lasted a hundred and fifty years, went forth the Catholic Church. The monuments of this struggle and witnesses of this
