But that is exactly what he said. Repentance for the Jew and faith for the Gentile. How can a Gentile's thinking about the Messiah be wrong and need changing if they have never been told in the first place?
But Peter demanded no repentance of the Gentiles while they believed onto salvation by simply believing in the crucified Christ.
Its the Jews where repentance became the issue in entering into what their bias and prejudices were fighting it.
In other words? We do not have to repent of our sins to be saved. That would be salvation by works..
