No better man could have been selected for the first part of this great work than Prof. H. J. Holtzmann, who is not only a theologian of most comprehensive scholarship but also has devoted his energies to this special subject. He has lectured regularly for a number of years at the university of Strassburg six or eight times weekly on the synoptic gospels and three times weekly on the Acts. The principle of his method has been laid down in a former work of his, viz. “Lehrbuch der historisch-kritischen Einleitung in das Neue Testament.” The present book contains an enormously voluminous material condensed into a comparatively small space of 448 pp. large octavo. The author being a theologian his attitude toward his subject is naturally reverent, paying an unreserved homage to the greatness of Jesus. Yet at the same time his investigations are strictly scientific and in accordance with the rules of criticism as employed in any historical investigation. It is no exaggeration to consider Professor Holtzmann’s work as representative in the highest degree; it embraces the most complete knowledge at present attainable and that too in a most concise form as a practical handbook with parallel tables and indexes of reference for students of the New Testament. The author first formulates “the synoptic problem,” which has been solved after innumerable vain attempts by the so-called “Marcus-Hypothesis,” which is at present considered as satisfactory, because it alone fulfils every condition and explains all the difficulties. Holtzmann regards the figure of Christ as historical. The impression of his powerful personality was a living presence in the first congregation at Jerusalem. But all the interest centred in his words. The words of their Lord were faithfully preserved by oral tradition. Sentences so short and yet so pregnant with meaning as “Blessed are the peacemakers,” or “Ye are the salt of the earth,” “But let your communication be, Yea, yea: Nay, nay, etc.,” are so impressive that whoever has heard them once, will never forget them. The interest in the word was soon complemented by an interest in facts and events which was much later followed by an interest in dogma. The first differences among the Christians originated through the mission among the heathens. The gentile Christian became indifferent concerning the Jewish traditions and clung with all his religious enthusiasm to the Christ as his saviour. Christianity became a cosmic religion while the Jewish Christians still looked upon Christ as the Messiah of the people of Israel. The Jewish view of Christianity is represented by Matthew, the gentile view by Luke. Mark however does not show any development of dogma. According to Papias, the Apostle St. Peter had whenever it became necessary for an explanation of the words of Christ, occasionally told certain events of the life of Jesus; which were afterwards written down by Mark. We find in Mark, Matthew,
