I am not an eastern Christian. I am main line but I am always kind of Shocked as by Protestants just not knowing or not caring about Eastern Christians. I bet so many don’t even know Iraq, Syria and Egypt are (or were) large population centers of ancient Christianity comprising a significant minority population.
I am western rite or Roman Catholic myself, and have always taken interest in reading up when posted on FR news in regard to those Christian communities you have posted in your post. They go back to the days of the Church under the Apostles.
