A leading N.T. scholar offers a judicious account of the anti-Jewish attitudes predating the rise of Christianity as well as his own analysis of the first stirrings of antisemitism among Christian gentiles. He also suggests that there was never a consistent pattern of anti-Jewish sentiment among either pagans or Christians. A convenient summary of his views may be found in his contribution to E. J.Fisher (ed.) Interwoven Destinies.
