Galatians 1:6-9

6I wonder that ye thus quickly change, from him that called you in Christ's grace, to a different gospel,

7which is not another [one]; but there are some that trouble you, and desire to pervert the glad tidings of the Christ.

8But if even we or an angel out of heaven announce as glad tidings to you [anything] besides what we have announced as glad tidings to you, let him be accursed.

9As we have said before, now also again I say, If any one announce to you as glad tidings [anything] besides what ye have received, let him be accursed.
