Paul speaks at the aeropagus
Paul had no concept like the trinity. But I'm not talking about trained Pharisees like Paul I mean the thousands of the earliest illiterate Hebrew christians.
the entire NT was written in Greek
I'm talking about before the NT was written. The first generation of illiterate Hebrew christians did not speak Greek. You said that it is impossible to explain the trinity without "the use of specific theological concepts encapsulated in the Greek language". Therefore these earliest christians could not have understood the trinity.
It follows that either belief in the trinity is of little importance or early christians were not christian.
the earliest Christians had a very high view of Jesus
I know they did... But that is a long way from the self-contradictory dogma of the trinity.
Your challenge still stands.
