From that link:
“Use of the Aramaic language had become common by the period of the Chaldean Empire (626-539 B.C.). It became the official language of the Imperial government in Mesopotamia and enjoyed general use until the spread of Greek (331 B.C.). Although Greek had spread throughout these Eastern lands, Aramaic remained dominant and the linqua franca of the Semitic peoples. This continued to be so until Aramaic was superseded by a sister Semitic tongue, Arabic, about the 13th century A.D. to the 14th century A.D., when Arabic supplanted Aramaic after the Arab conquest in the 7th Century. However, the Christians of Mesopotamia (Iraq), Iran, Syria, Turkey and Lebanon kept the Aramaic language alive domestically,
scholastically and liturgically. In spite of the pressure of the ruling Arabs to speak Arabic, Aramaic is still spoken today in its many dialects, especially among the Chaldeans and Assyrians.”
If Aramaic speakers–about five hundred thousand souls today–are already mostly Christian, how would this language be useful to the OP for evangelization among the Arabic-, Persian-, Turkish-, and Kurdish-speaking Muslims of the Middle East?
