What did the first Christians in Antioch believe about Jesus that the Jerusalem believers did not?
The believers first called Christians at Antioch believed Jesus had died for them, that His blood had been shed for their sin, and that He had been raised from the dead. Jerusalem's Jewish believers had only believed Jesus was Israel's Messiah, remaining under the Judaistic umbrella and not receiving Paul's gospel.
Les explains that Barnabas brought Saul to Antioch, and for a whole year they assembled with the church and taught much people. There the disciples, primarily Gentiles, were called Christians first. Les asks why not Jerusalem, since the Jerusalem church had already been holding forth for twelve years. The Bible never calls the Jewish believers at Jerusalem and Judea Christians; they were under the Judaistic umbrella and had only believed Jesus was the Messiah of Israel. But these Antioch Christians believed He had died for them, His blood had been shed for their sin, and He had been raised from the dead. Antioch was being presented with Paul's Gospel, which was a secret held in the mind of God until it was revealed, something totally different.
