The Vatican, the seat of papacy and the head of Catholic Christianity, rejected the British custody of Palestine Project, which it said might have threatened equality among religions. Also, the Vatican reiterated its opposition to the establishment of a national home for the Jews in Palestine. Since the beginning of the Arab-Zionist struggle, the Vatican has used two approaches:
1. Strengthening relations between the Catholic Church and the Arab World, so that the first protects the interests of Christians in the East, and building a united Muslim-Christian front against ‘blasphemy and Communism’.
2. Formulating understanding between Christians and Jews despite the dominant hostility that was based
on the Christians firm belief that Jews were the ones who crucified Jesus. Based on this policy, and in the aftermath of the 1948 War, the Vatican requested the internationalism of Jerusalem, refused to recognize the Israeli State, and
supported the return of the Palestinian refugees strengthening relations with Arabs. At the same time, it worked to clear Jews of the murder of Jesus Christ, consider Judaism an independent religion, and remove some parts of the Bible that are against Jews.
