How are people today still treating Paul the way the early churches did?
Many today, prompted by Judaizers, still undermine Paul's apostleship and insist his gospel of grace is insufficient. They claim believers must also practice Judaism, be circumcised, and keep the law, just as the early churches did. This adds works to salvation and rejects the law as satisfied and set aside.
Les teaches that a lot of people today are still treating Paul the same way the early churches did, and they are prompted by the Judaizers. He explains that a Judaizer was a believer who accepted that Jesus was the Christ and was saved under the kingdom gospel, but still did not comprehend the grace of God or that the law had now been satisfied and totally set aside. So the Judaizers constantly followed in Paul's footsteps, telling his converts they could not be saved on Paul's gospel alone; they still had to practice Judaism, be circumcised, and keep the law. Les says this just about drove the apostle up the wall, and Paul suffered because of it. Paul had to defend his apostleship and repeatedly point to all he had suffered so the Gentiles could get this message of grace, which is basically the theme of the first six chapters of Corinthians.
