Yeah well, back in the olden days when jebus was still a carpenter instead of herding sheep they spoke hebrew and aramaic. The powers that STILL be, spoke latin.
It is said that arabic is a created language, at least the written form. It was done by greek explorers, like the europeans did AGAIN last century.
So in essence, i think the greek wrote it all down in israel and the peter took his version to rome, were he figured out the lie, got hung updside down and out of his pocket fell the ROMAN church, which is quite different from the greek orthodox aka aramaic church. As a side note they have been killing aramaic people for a while now similar to the killings of the yazidis.
The most strange thing i found about this language trap in that area of the world, is an old Mesopotamian rhyme, were it says the greek are liars.
i forgot the timelines on this, but history and the trilogy is like that: a big mess. Its even worse when you take the council of rome ad 382 into concideration.
Sorry for the chaotic view, but finding reliable info in the trilogy is like that. They dont like me there.
