This book discusses the development of the Doctrines of Salvation and Atonement from one end of the Bible to the other. It seeks to show that a single doctrine gradually emerges, which can be best stated in psychological terms. The chief Old Testament contribution is found in the Prophets, the ritual system furnishing no more than a secondary source. Under the New Testament there is a detailed expository attempt to show that, while the experience of salvation from sin through the Death of Christ is the fundamental fact, the explanation of that experience, starting from a large and varied use of the Fifty-third of Isaiah, issues in what may be called a 'societary' doctrine of the Atonement. The author claims that Saint Paul, the Writer to the Hebrews, and the Writer of the Johannine Books, all hold this doctrine, though each states it in his own way.
