Gal 1:8 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.
Gal 1:9 As we said before, so say I now again, If any [man] preach any other gospel unto you than that ye have received, let him be accursed.
Paul's gospel is the gospel that saves. If you read 1 Cor 15:1-4 that is the gospel that saves.
Shake it easy, baby
