“I am astonished that you are so quickly deserting the one who called you to live in the grace of Christ and are turning to a different gospel—which is really no gospel at all.” Galatians 1:6-7
False teachers were trying to convince the Galatian believers they had to conform to the Old Testament laws and rituals to be saved. These teachers denied the saving power of God’s grace. But, as soon as we add a ritual to our salvation it becomes an entirely different gospel. We are saved by grace alone, nothing we do achieves or enhances our salvation.
