Well, we have a protagonist who has a topic that while somewhat true, all the motives seem to be wrong.Please be more specific.
Then we have several antagonists who while looking good, correct, & proper, & even popular, are theologically wrong.
It seems the theme is to take a not-so-good guy with a good doctrine overshadowed by what seems to be nice, polite, & popular members who are totally against him, making him look bad & unbelievable for the sake of confirming their false doctrine that will send unsuspecting souls to Hell.
Sorry to be blunt, but I couldn't find a softer way to explain it. I hope this helps.
