'Arguably no relationship of any two faith communities in the course of history has been both so close and so far apart as that of Jewry and Christendom. Yet this new era has both produced and affords a relationship between the two … in which both the profound differences as well as the 'shared patrimony' can be genuinely appreciated. This Dictionary will have a special place in reflecting and facilitating this process.' Rabbi David Rosen, President, the International Jewish Committee for Interreligious Consultation, International Director of Interreligious Affairs, The American Jewish Committee
