You don’t know very many Ethiopians, do you? I think it is all relative to how much of an impact or influence Protestantism has had on the people. So, since Protestantism is not very big in places like Russia, Bulgaria, etc., you won’t find many who address it directly. But if you look at Ethiopia, where Protestants have grown quite a lot at the expense almost entirely of the native Orthodox Christians and their Church, you’ll see many, many people addressing it directly. Granted, they address it usually in Amharic, so I don’t know what they’re saying exactly, but there are lots of videos like this one that apparently show the efforts of Ethiopian Orthodox to fight against Protestantism in their country and among their peoples, in very explicit terms (I am familiar enough with Amharic and general Semitic languages that I recognized “Protestantawi Jihad” being referenced there…yikes).
The Copts, I am sad to say, are somewhat behind the curve on this stuff (having only encountered Protestants in significant numbers outside of Egypt, in the recent and growing diaspora), though some are addressing it already, and also HH Pope Shenouda III has addressed it to some degree (can’t remember exactly where, but in addition to the bit near the end of the interview, there is some point, perhaps in part 1, where he talks specifically about Jehovah’s Witnesses; since I can’t remember where, maybe you should watch both parts. :))
I expect because many would view Protestants as “the wayward children of Rome” and have an attitude of “we didn’t create the problem, so we don’t have to fix it”. With Protestant so-called missionary efforts in historically Orthodox countries being underway for decades now, this complacency has to be discarded. If I were fluent in Spanish and Portuguese, I would gladly head down to Latin America and set up shop among the Pentecostals.
This is certainly a sensible view from an EO perspective, given the much longer history they have with Rome than we do.
There is great missionary work being done in Latinoamerica by EO and OO alike. as you can see by videos like this, and this, and this, and this, etc.
The church at which I was baptized, St. Mark COC in Arizona, gave a presentation when I was there by two of the young servants (teenaged girls) who had served the people in Bolivia. It was very inspiring. Apparently over 400 native Bolivians attend in La Paz every week, and the Orthodox work among people in the countryside well outside of the capital where nobody visits. They have found the people there to be very appreciative, but most importantly very dedicated to God. One of the girls said that there is a young boy who now lives in the orphanage who took over upon their leaving, so much was his love for the Church. So the missionary effort is yielding good fruit throughout the world, glory be to God. Incidentally, I speak Spanish more or less natively, since age 3 or 4, and that was the first thing they recommended: “OH, GOOD! You can come with us when we go back, then?” I had just been baptized about two hours earlier!
