Now even though it were myself or some angel from heaven, whoever preaches a gospel that contradicts the gospel I preached to you, God's curse be on him!
I have said it before and I now repeat it: whoever preaches a gospel to you that contradicts the gospel you have already received, God's curse be on him!
so I tell you now, that no one is speaking in the Spirit of God when he cries, 'Cursed be Jesus,' and that no one can say, 'Jesus is Lord,' except in the holy Spirit.
Whereas a curse rests on all who rely upon obedience to the Law; for it is written, Cursed is everyone who does not hold by all that is written in the book of the law, to perform it.
Brothers, I beg of you to keep your eye on those who stir up dissensions and put hindrances in your way, contrary to the doctrine which you have been taught. Avoid them.
