Galatians Chapter 1

But even if we or an angel from heaven should preach to you a gospel contrary to the one we preached to you, let him be accursed. For I would have you know, brothers, that the gospel that was preached by me is not man's gospel. But when he who had set me apart before I was born, and who called me by his grace, was pleased to reveal his Son to me, in order that I might preach him among the Gentiles, I did not immediately consult with anyone.
