It has been for many years a hope of mine that I might find the time to formulate, in a systematic fashion, the ethical teaching of the New Testament, and particularly of the Gospels. This would be a major undertaking, and what I write now falls far short of this. But it is not unrelated to it; for it arises from repeated, if unsystematic, reflection upon the conditions of fulfilling such a project. Certain problems have presented themselves for solution which I cannot solve. Certain possible conclusions, between which a choice must be made, compete with one another for acceptance. Certain valuations which seem to differentiate the teaching of the Gospels from other ethical attitudes have focused themselves in my attention, without achieving systematic relation to one another. It is something of all this that I have in mind to express; no firm conclusion, certainly, but rather certain prolegomena to any conclusion which may eventually become possible.
