The Roots of Eastern Christians in the Middle East: From the Origins of Christianity to the Latin Crusader Kingdoms.This Book is about the real ethnic roots of the Eastern Christians as they don't have Arab roots and they don't have Arab origins. These Eastern Christians have Non-Arab origins and the Term Arab Christian is wrong and not correct as Walid Phares wrote in his article regarding the Arabic Bible. the real Arab Christians of different Kingdoms and tribes vanished in the 10th century. Therefore, if these Christians in the Arab World, the Middle East, the Levant and the Holy Land- Palestine, speak Arabic as their native language it doesn't mean that they are Arabs. The Term Arab Christian is considered an ethnic cleansing term of the real Ethnic roots of the Middle East in the Pre-Islamic times. The Eastern Christians are Mediators between East and West, there is a problem of Identity and affiliation regarding their relations with the Byzantine Emperor and the Crusades in regard to their position from the conflict between Islam and the West.
