Paul taught that there was only "one" gospel !
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.
Who is the 'we' that preached in vs 8?
Received from who in vs 9?
