“Which is the correct version; the Slavonic Bible or the American Greek Orthodox Bible?”
That’s easy, HD, the Slavonic bible. It is as accurate a translation of the Greek NT and the Septuagint as there is because Church Slavonic was intentionally designed to be an accurate translation of Greek. By the “American Greek Orthodox Bible”, I assume you mean the Study Bible. That is NOT a translation of the official Greek Bible of the Church of Constantinople which is the “official” Orthodox bible. The Study Bible is in no way official. There is no official translation of the bible into English for the Orthodox.
LOL!!! I should have saw that coming!!! :O)
