Galatians 1:8-10

New Catholic Bible

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]

¹⁰ Does it now appear to you that I am trying to gain the approval of human beings rather than the approval of God? Am I seeking to please people? If I were still trying to please people, I would not be a servant of Christ.
