You could also go a bit more Final Destination with it.Oh dude! What about a horror movie about the Holy Spirit? Feeding on souls. The trailer would show a child saying prayers before bed. And everyone they pray for, becomes prey. Bless grandma, and cut scene showing grandma putting her face into a food processor. And she's all trying to stop it, like, no, no, no, bwarararararararararrerrrrrrrrrrrrrr, aaaahhhhhhhhhhhhhhhh!
What do y'all think? Too dogmatic?
Grandma pierces her eyeballs falling on her knitting needles or something.
Have the holy spirit doing rails of her blood.
Or do you want Jesus killing people?
