RE: Heretic (2024) - Psycho killer, qu'est-ce que c'est?

You didn't miss much ;) I didn't think it went into much depth on any religious angle to be honest. Didn't even see why it had to be two Latter Day Saints girls, honestly. Probably the going to people's houses just offered the writers a good, easy lead... though I did find it interesting (and vaguely creepy on the producer's part) that the actresses hired actually both had a LDS background.
