Depends on your definition of angel
Okay, let's look at the verses in context then.
1 Corinthians 6:1-3
1 When one of you has a grievance against another, does he dare go to law before the unrighteous instead of the saints?
the saints will judge the world? And if the world is to be judged by you, are you incompetent to try trivial cases? 3 Do you not know that we are to judge angels? How much more, then, matters pertaining to this life!
It says the saints will judge the world. This verse is talking about other human beings. The next verse then reveals
another group we will be responsible for judging as Christian's: Angels. Your interpretation doesn't make sense because there's no reason for Paul to change descriptive terms here if he were talking only about human beings. He uses the term "angel" as an
additional party that we will
also be responsible for judging.
You say you judge messages here, but we all do that, tbh.
