Gibberesh. Shut up.
Yup, your cryptic one-line statement WAS gibberish. That's the point. It can be interpreted two completely different ways: 1) Paul was "up to his neck" in OPPOSING Gnosticism, or 2)Paul's teachings themselves were somehow Gnostic (which is what it actually seems to mean). And what I have been trying to do since you posted that gibberish was to get you to say WHICH of the two meanings was the right one, hopefully with come background--but you want to play head games.
So, which was it???
