No. Those events actually happened. That's why there is so much confusion today concerning this issue. They (the Bishops) didn't realize the problems it created.
If ancient Arabs believed in Jesus (the Biblical Jesus), someone had to explain to them how to be born-again. They must have called on the name of Jesus in their Arab language. If they call GOD the Father "Allah", they would still be saved, but they would be in error
You still didnt answer the Question. What name did Arabic speaking Christians use to refer to G-D in the Arabic Language before Islam?
