Now hang on just a second...
These Palestinian Israeli Arabs...are they Christians or moslems? Or are there both?
They are both, with the overwhelming majority being Muslim. To give you some numbers to chew on, here’s something you can consider ...
Religion in Israel is a central feature of the country and plays a major role in shaping Israeli culture and lifestyle, and religion has played a central role in Israel’s history. Israel is also the only country in the world where a majority of citizens are Jewish.
According to the Israel Central Bureau of Statistics, the population in 2011 was 75.4% Jewish, 20.6% Arab, and 4.1% minority groups. The religious affiliation of the Israeli population as of 2011 was 75.4% Jewish, 16.9% Muslim, 2.1% Christian, and 1.7% Druze, with the remaining 4.0% not classified by religion.
Israel has no entrenched constitution, but freedom of religion is anchored in law. While the Basic Laws of Israel that serve in place of a constitution define the country as a “Jewish state,” these Basic Laws, coupled with Knesset statutes, decisions of the Supreme Court of Israel, and various elements of the common law current in Israel, also protect free practice of religion in the country.
Legal accommodation of the non-Jewish communities follows the pattern and practice of the Ottoman and British administrations with some important modifications. Israeli law officially recognizes five religions, all belonging to the Abrahamic family of religions: Judaism, Christianity, Islam, Druzeism and the Bahá’í Faith.
Furthermore, the law formally recognizes ten separate sects of Christianity: the Roman, Armenian, Maronite, Greek, Syriac, and Chaldean Catholic Churches; the Eastern Orthodox Greek Orthodox Church; the Oriental Orthodox Syriac Orthodox Church; the Armenian Apostolic Church; and Anglicanism. Members of unrecognized religions are free to practice their religion.
