The church at Galatia was severely affected by the false teachings of the Judaizers who wanted the believers in Galatia to follow the Law of Moses and be circumcised. Paul deals with their false doctrines and their attacks with instructions in his letter that speak boldly and with authority against these teachings, laying out sever consequences to those who skew the grace only message of the gospel. He writes,
Gal.1:6 I marvel that ye are so soon removed from him that called you into the grace of Christ unto another gospel: 7 Which is not another; but there be some that trouble you, and would pervert the gospel of Christ. 8 But though we, or an angel from heaven, preach any other gospel unto you than that which we have preached unto you, let him be accursed.
