What did Paul say was happening to the Galatians with the gospel?
Paul said the Galatians were being moved from the pure gospel he had proclaimed to them and were listening to people who troubled them and perverted the gospel. Those people used the same things Paul preached but added to, took from, or twisted it, so it became another gospel.
Les explains that Paul's concern in Galatians is that the Galatians were being moved away from the pure gospel he had proclaimed to them. The "another gospel," Paul says, is not something completely different, because then it would be recognized immediately as a false gospel. Rather, some were troubling them and perverting the gospel—twisting it out of shape. They were basically using the same things Paul preached, but adding to it, taking from it, or twisting it, so that it became another gospel. Paul then pronounces a strong curse: even if he, an angel from heaven, or any man preached any other gospel than what the Galatians had received, let him be accursed. Les points out that to be accursed is to be separated from God forever.
I marvel that ye are so soon removed from him that called you into the grace of Christ unto another gospel:
