Ethnicity

Paul is a Jew speaking to Gentiles (a region of mostly Celtic Gauls) about how salvation, through Jesus Christ, works for all people. The emphasis of this letter comes because a group of Jews (historically known as the Judaizers) were teaching these Gentile Christians to live according to the Jewish Law and follow Jewish customs. Paul is calling them back to embrace the new ethnicity they embraced called "the way." Paul does not have to stop being a Jew to be a Christian and the Galatians do not have to stop being Celtic Gauls to be Christians.
