In the wake of President Sadat's groundbreaking 1978 visit to Jerusalem, a watershed moment opened unexpected channels for Jewish-Muslim dialogue. Seizing this diplomatic window, an unprecedented American Jewish religious delegation - uniting Orthodox, Conservative, and Reform leaders - embarked on a week-long mission to Egypt that would test the boundaries of interfaith engagement during a pivotal moment in Arab-Israeli relations. Through direct diplomatic meetings with President Anwar Sadat, Deputy Foreign Minister Boutros Ghali, the Grand Imam of Al Azhar, and Cairo University faculty, the delegation explored possibilities for sustainable religious and cultural cooperation. Their methodology combined participant observation with structured diplomatic engagement, including visits to Jewish historical sites and meetings with Cairo's remaining Jewish community. While religious authorities maintained intractable positions on Jerusalem and territorial issues, revealing deep-seated barriers to theological dialogue, more promising avenues emerged through academic and governmental channels. These included agreements for cultural exchanges, preservation of Jewish heritage sites, and the return of confiscated Torah scrolls. The mission ultimately illuminated how religious diplomacy could both complicate and enhance political negotiations, exposing fundamental narrative conflicts while identifying practical opportunities for cooperation that transcended immediate political deadlock in the peace process.
