Former Eastern Orthodox (Joshua Shooping) priest who returned to Protestant Faith explains some key reasons and his book, “Disillusioned”- icons in worship context and the EO demand that one has to venerate them with affection; the over-exalting of Mary in the EO canonical prayers, and the exclusive claims that EO makes for itself as the only true church. It seems also that the tendency of EO communities to become cultural enclaves is also part of the problem. (Greek, Russian, Ukrainian, Bulgarian, Serbian, etc.) Shooping has been on Gavin Ortlund’s You Tube channel at least twice and Tony Costa’s You Tube also. (see 3 videos below)
Check out Joshua Shooping’s book, “Disillusioned”. All of his points are documented from EO sources in that book. It seems Amazon or some kind of extension is blocking me from linking to his book here. However, I was able to copy the image of the book.
Shooping is now a Protestant pastor in the Christian & Missionary Alliance Church. (think A. W. Tozer and A. B. Simpson) He knows Church History and the EO sources well and historical theology. He discovered Penal Substitutionary Atonement in the early church fathers.
