"He shall be a wild ass of a man; his hand shall be against every man, and every man's hand shall be against his. He shall dwell against all his kinsmen."
-The Angel of the Lord, about Ishmael. (Gen. 16:12)
What this has to do with the topic?
Islamic traditions consider Ishmael to be the ancestor of Arab people, excluding Arabs who are descendants of Ya'rub. Arabs who are from Ishmael-descendant tribes are occasionally referred to as "Arabized-Arabs" to highlight their ancestry. The Prophet Muhammad was of these Arabs.
Please note, however, that there is hardly a consensus on this point, and opinions like this often play into racism, which I would like to avoid like the plague...
I agree with Father Cyprian.
How many of our Church Fathers from Asia Minor (Cappadocia) are of Arabic descent?
How many beautiful big brown eyed dark-haired Arabic brides did Alexander's men bring back to Greece?
Weren't the ancient Greeks before the reign of Alexander usually blonde and blue eyed?
And finally, was not the first church established by Saints Peter and Paul that of Antioch?
Let us pray for the conversion of Muslims and for their salvation.
