Paul was shocked that the Galatians were turning to a different gospel taught by those who wanted to distort the true gospel of Christ. Paul warns that if anyone, including an angel, teaches a gospel contrary to what was originally received, they should be eternally condemned. The Judaizing teachers were demanding Gentile Christians follow the Law of Moses to be saved, but Paul says there is only one gospel that can save. Paul would still be shocked today by those who pervert the gospel by ignoring or loosening its demands, and insists there remains only one true gospel.
