Arianism is the archetypal Christian heresy. It was not only a watershed historically; its central issue-the question of Christ's full co-equal divinity as Son of God-remains an issue of deep concern to every generation of Christians, including our own. The traditional critique of Arianism is that its errors arise from an over-intellectual approach to Christianity, that it failed because it lacked a gospel of salvation. Questions about that traditional view have been raised here and there in recent years. This book challenges it head on. It does no on a basis of careful scholarship, and at the same time in a lively and readable style.' Maurice Wiles, Regius Professor of Divinity in the University of Oxford 'Gregg and Groh have enabled us to see the thought of Arius on the nature of Christ as condensing nothing less than a distinctive view of man, congruent to a precise social and religious milieu. As a result, the clash of disembodied dogmas becomes suffused with the quality of a late Roman Christian's most urgent concerns: "love and betrayal, grace and backsliding". Now presented with liberating precision in all its implications-from conflicting attitudes to change and stability in society and the universe, to vivid glimpses of the bustling world of Greek cities contrasted with the unearthly stillness of St Anthony in the desert-a well-worn chapter of Christian dogma emerges as a high moment in the birth of a new civilization in the Roman world. This is a model book, that any scholar of Christian doctrine would dearly wish to have written; and that every scholar of the early Christian world must read.' Peter Brown, Professor of History and Classics in the University of California at Berkeley 'Gregg and Groh propose a novel approach to the most profound crisis of the dogmatic tradition in the ancient church. They extract from the denunciation of the errors of Arius ... a striking view of the ancient doctrine of salvation. The principle aspects of this doctrine remain too often neglected by the critics. But with Gregg and Groh the saviour God of Arius is brought back to life, reactivated ... The authors display in convincing fashion the original accents of this doctrine, at the heart of the Christian community, before it had become nothing but a heresy charged doctrine... They promote a healthy reflection on the more fixed forms of antiArian dogmatism, passively transmitted over the centuries.' Charles Kannengiesser, Professeur a Onstitut Catholique de Paris

While existing scholarship informs us about early contact between Christians, Muslims, and Jews, the nature of that interaction, and how it developed over time, is still often misunderstood. Robert Gregg emphasizes that there was both mutual curiosity, since all three religions had ancestral traditions and a commanding God in common, and also wary competitiveness, as each group was compelled to sharpen its identity against the other two. Faced with the overlap of many scriptural stories, they were eager to defend the claim that they alone were God's preferred people. In Shared Stories, Rival Tellings, Gregg performs a comparative investigation of how Jewish, Christian, and Muslim interpreters-both writers and artists-developed their distinctive and exclusionary understandings of narratives common to their three Holy Books: Cain and Abel, Sara and Hagar, Joseph and Potiphar's Wife, Jonah and the Whale, and Mary the Mother of Jesus. Exposed in the process are the major issues under contention and the social-intellectual forces that contributed to spirited, creative, and sometimes combative exchanges between Muslims, Christians and Jews. In illuminating these historical moments, and their implications for contemporary relations between these three religions, Gregg argues that scripture interpreters played an often underappreciated role in each religion's individual development of thought, spirituality, and worship, and in the three religions' debates with one another-and the cultural results of those debates.
