All the romance languages -- Medieval Latin, Italian, Romanian, Spanish, Portuguese -- derive primarily from an early unified form of Latin, which you refer to as Ancient Roman, which, while you are correct in that it could be called proto-Italian, it could also be called proto-Spanish or proto-Romanian. It's commonly referred to in linguistic circles as Ancient Latin.
any physical Greek occupancy in the Roman provinces
The Jews in the Roman Provinces descended from the Hellenized Jews, of the early Jewish post-exile Diaspora. The so-called founder of the Catholic Church, Simon Peter, is widely agreed to have spoken Greek (although the body now known as the Catholic Church was not established until the 300s), as did most first-century Christians.
but the over 1,000 years of spiritually imposed occupancy in the field of eternal words of Scripture by the Mother (great in size) Roman church and the State of Vatican.
So, I'm confused. You believe the scriptures were written in Ancient Italian because of the authority of the Catholic Church as opposed to all historical evidence to the contrary?
The facts are indisputed: we know that the Hebrews were exiled from the Promised Land roughly 400 BC, and in that time were dispersed among all of Eurasia. Historians and theologians call this the Diaspora. During the ensuing centuries, the Hellenized Jews incorporated Greek culture and language into their own. Jesus was born into a Hellenized Jewish province of the Roman Empire. As a direct result, the earliest Christians spoke Greek and not Latin. Nobody disputes this -- not even conservative Christian scholars.
It wasn't until the Christian church was Romanized in the 300s AD that the ancient Roman translations of the scriptures became "authoritative". If you're going to argue NT Theology based on linguistics, you
must use the Greek manuscripts. We have plenty of them, faithfully preserved, and they even pre-date the Catholic Church. Saying the original scriptures are in the Ancient Roman language is simply a lie.
At any rate, we're definitely going off topic and I'm not going to respond to further posts on this thread about the current subject. We can start a new thread to continue this discussion if you would like.
