I too do not speak Arabic, but my bishop, the old Arab chanter from whom I learned Byzantine chant such as I know it, many Orthodox priests I know, and a lot of the faithful in largely immigrant parishes of our Archdiocese I have visited from time to time, including the old woman named Inshallah, do.
The Trisagion Prayer, which runs in English, “Holy God, Holy Mighty, Holy Immortal, have mercy on us,” in Arabic is “Quddouson Allah, Quddouson il-qawee, Quddouson alladhee la yamout, Irhamna.” Those of us who pray it, whether speaking English or Arabic are praying to the All-Holy Trinity, not any pagan moon god, nor are we praying to one whose proper name is Allah, which is why Arabic speaking Christians only call God Allah when speaking Arabic — neither the Arabic “Allah” nor the English “God” is the proper name of the Existing One, but Allah is the Arabic word for God, just as God is the English word for God.
