The attitude of Karl Barth to Israel and the Jews has long been the subject of heated controversy amongst historians and theologians. The question that has so far predominated in the debate has been Barth’s attitude, both theologically and practically, towards the Jews during the period of the Third Reich and the Holocaust itself. How, if at all, did Barth’s attitudes change in the post-war years? Did Barth’s own theologising in the aftermath of the Holocaust take that horrendous event into account in his later writings on Israel and the Jews? Mark Lindsay explores such questions through a deep consideration of volume four of Barth’s Church Dogmatics, the ‘Doctrine of Reconciliation’.
