This work is a biography of James William Parkes, one of the pioneers in the field of Jewish-Christian relations and the study of antisemitism. This ordained Anglican priest made significant and controversial contributions as both historian and theologian, carefully documenting how Christianity from its earliest centuries to the present has continuously misunderstood the nature and history of Judaism, thus contributing to antisemitism in its many forms. Parkes also provided a useful model for helping Christians to deal honestly with Judaism and Jewish history and to shake off historical and theological misconceptions that may have prevented a clear understanding of the Bible and of Christian theological traditions. By placing these aspects of Parkes' work in context, Robert Everett shows that Parkes was not simply a "philo-semite", but rather a Modernist theologian who applied his Modernist theological critique of Christianity to the question of Jewish-Christian relations.
