Claims to Greek from "From Jesus to Christ"

[Gentile]

The ancient Hebrew texts were used in religious services, while the modern Aramaic vernacular was spoken outside of the synagogue.....for the same reason why the ancient Aramaic language is used in Church services today, while the modern vernacular Aramaic is spoken at home. The religious texts are fixed in the ancient language. Nobody can translate them or change even one letter in them.

Languages evolve. A language that doesn't evolve is a dead language. But the texts always remain fixed and unchangeable.

Similiarly, the ancient Arabic of the Koran is used in Mosques. But the modern Arabic is spoken outside of the Mosque. But nobody changes the Koran into modern Arabic

But they can still be understood straight off by speakers of the language, even though they speak just the modern version right? Is it just a case of for example going into a church now and hearing stuff like "Thou shalt not covet" which I, an English speaker, can understand even though I don't actually speak this way as I speak modern English. Is it the same kind of situation?
