'Condemned' in the Bible

But even if we or an angel from heaven should proclaim to you a gospel contrary to what we proclaimed to you, let that person be condemned!

What we have told you in the past I am now telling you again: If anyone proclaims to you a gospel contrary to what you received, let that person be condemned!

But when Cephas came to Antioch, I opposed him to his face because he stood condemned.
