Paul writes to the Galatians in the New Testament to bridge the two realms of cultural Judaism and Roman Imperialism. In this analysis of the letter written to the church of Galatia, we see both Hebraic prophecy and Greek, or Gentile, parrhesia. As the context shows, Paul attempts to persuade a hybrid audience on the edge between the two ancient cultures. Paul diagnoses the church’s problems through a prognostic teaching that fulfills a larger Pauline gospel agenda. Future scholars will need to attend to the work of both parrhesia and prophetic rhetoric in Christian texts over the two millennia since Paul’s initial fusion.
