Modern theology reveres the names of Karl Barth, Rudolf Bultmann and Emil Brunner, hailed as the heroes of a new, modern and re-stated Reformation theology - a new orthodoxy for a new age.
In this book, Iain D. Campbell focuses on one doctrine - the doctrine of sin - and views it first in its biblical perspective, and then considers the perspective of the Reformers and Puritans. He compares and contrasts their approach with that of Barth, Bultmann and Brunner. He also shows how the modern theologies have evacuated the Evangel of its power and saving influence by reducing the sin of man to little more than personal dysfunction.
The Gospel is shown to be the power of God to salvation, because there is an emphasis on sin as objective and factual, leaving people in need of the saving work of Jesus Christ. The new orthodoxy is shown to be not a re-statement of the Gospel, but as Paul reminded his readers long ago, 'a different gospel'.
