PREFACE
IN this small book I publish four lectures which I was invited to give in a course of "advanced lectures in theology" at the University of London, March, 1913. The lectures were for the most part originally written in German. I translated them with the kind assistance of Miss Ida Southhall, M.A., of Birmingham, then a guest at my house. But it is not she alone to whom I am indebted. I have also to thank my dear host during my stay in London, Professor H. J. White, who read two of my lectures before I gave them, and the corrector of the Cambridge University Press and two of our American students, Mr H. Harper, B.A., of Avalan (U.S.A.), and Mr Charles Baillie, B.D., of Picton (Canada), whose kind suggestions I often utilized in reading the proofs. However, I beg my readers to put it to my account, that in spite of all these friendly helpers, the German author very often reveals himself.
In quoting Nestorius' "Book of Heraclides" I have given the pages both of the Syriac text and of Nau's French translation—not in order to raise in my reader's mind the idea that I made use of the Syriac text.
