Galatians 1:7-9

New Catholic Bible

⁷ In reality, there is not another one, but there are some who are troubling you by perverting the gospel of Christ. ⁸ But even if we or an angel from heaven should preach a gospel to you other than the one we proclaimed to you, let him be accursed! ⁹ We have said this before, and now I repeat it: if anyone preaches to you a gospel other than the one you received, let him be accursed!^[a]
