On the other hand, the gospel of Paul was not and still is not the gospel of Jesus. The gospel of Paul is Hellenist aka the NT and the gospel of Jesus is the Tanach; aka the Law and the Prophets. (Matthew 5:17-19
and Luke 16:29-31.
That's strange.
Why do you suppose Jesus gave his Gospel to Paul? Galatians 1:11, 12.
