[[6]] See especially O. W. Emmet, The Eschatological Question in the Gospels and other Studies, pp. 191 ff., and K. Lake, The Earlier Epistles of St. Paul, pp. 274 ff.
[[7]] The most important names in the first period are Königsmann, Schleiermacher, Gfrörer, and Schwanbeck, especially the last; in the second period B. Weiss, Wendt, Sorof, Jüngst, J. Weiss, Spitta, Clemen, Hilgenfeld. In general the work of this group is inferior in value to that of their predecessors. A clear and invaluable summary of both is given by W. Heitmuller in the Theologische Rundschau for 1899, pp. 47 ff.
[[8]] Perhaps Norden's name should be added, but interesting and stimulating though his book Agnostos Theos be, it suffers from ignorance of early Christianity, and has little permanent value for the criticism of Acts.
[[9]] A. von Harnack, Untersuchungen zu den Schriften des Lukas; E. Schwartz, "Zur Chronologie des Paulus," in the Göttingische Nachrichten, 1907, pp. 263 ff.; C. C. Torrey, "The Composition and Date of Acts," in the Harvard Theological Studies, i. The most damaging criticism of Torrey is that of F. C. Burkitt in the Journal of Theological Studies, Oct. 1919, but I do not think that he answers Torrey's case.
