What does Paul's gospel to the Gentiles exclude?
Paul's gospel to the Gentiles excludes circumcision and law keeping. It is not directed to those who keep the Law or do something, but to those who simply believe. This was a new concept the Jews could not comprehend in Paul's preaching.
Les explains that Paul communicated the Gospel he preached among the Gentiles privately to those of reputation—the leadership, including Peter and the eleven, and perhaps other Jewish elders. That Gospel leaves out circumcision and law keeping, which the Jews could not comprehend. Paul also notes that Titus, a Greek convert with him and Barnabas, was not compelled to be circumcised.
