If predominenty Latinate Catholic conservatives within the Roman Curia were opposed to any document on the Jews for theological reasons, then the Arab world (whether Muslim or Christian) was concerned with it for immanently political reasons, relating to the Arab-Israeli conflict. Egypt, then under the leadership of Gamal Abdel Nasser, particularly concerned itself with all Vatican documents on the Jews which were published since the time of Isaac's visit to Roncalli back in 1960. The "Voice of the Arabs", based in Cairo, ascribed this move to a "Zionist plot to capitalize on the Vatican Council in order to further the oppression of the Palestinian refugees." The Lebanese Embassy and the Egyptian Embassy in Rome made their complaints known to the Vatican. In spite of this, Roncalli allowed the SECU under Bea to continue its work on a document on Jewish-Catholic relations. Bea openly met with Ralph Friedman and Zacariah Shuster of the American Jewish Committee at Rome in 1961, inviting them to submit a memorandum on anti-Jewish elements in Catholic textbooks and liturgy. The AJC responded to the SECU with two documents; ""The Image of the Jew in Catholic Teaching"" and then ""Anti-Jewish Elements in Catholic Liturgy""; outlining the changes to Church teachings and practices that they wanted the planned Council to implement. As part of this, Bea also agreed to meet with Abraham Joshua Heschel of the Jewish Theological Seminary of America and Max Horkheimer of the Frankfurt School in November 1961 to discuss new Church approches to the Jews.
