That’s one hell of a controlling scripture if you think about it. Paul, or some modern day preacher can really keep the flock in line with that doozy of a verse..
What if the being who reportedly appeared to Paul in a vision wasn’t really Jesus? Now here’s Paul basing his teaching on something that could be “Demonic” but he’s telling the flock not to believe Angels over his message.
So if Jesus sends an Angel to someone and that message contradicts what Paul says...?
What a marvelous passage to support any interpretation of the Gospel and to tell any given flock that you’re Da Troof, whatever your denomination.
