The reason for no music and no dancing in Footloose 1984 is the same as in Footloose 2011.
In the original, we know as much about Bomont as Ren knows. We're not clubbed over the head with graphic flashbacks. Instead, we're given the reveal of why no music and no dancing in a moody, evocative scene as Ren & co. return to town from a night of drinking and dancing, driving over the very same bridge where Rev. Moore's son died.
Rev. Moore's fire and brimstone is rooted in his pain over the loss of his son. He is trying to atone for what he saw as a personal failing:
"One of these days, my Lord is going to come to me, and ask me for an explanation for the lives of each and every one of you. What am I going to tell him on that day? That I was busy? That I was tired? That I was bored? No! I can never let up! I welcome his test. I welcome this challenge from my Lord, so that one day I can deliver all of you unto his hands. And when that day dawns, I don't want to have to do any explaining! I don't want to be missing from your lives!" (Quoted from an online transcript, so it may be off a bit from the actual dialogue.)
Moore feels that he failed the test, he was missing from his son's life, and he will have to explain this failing one day. Later, when the townsfolk are burning books, Rev. Moore confronts them:
"When did you all decide to sit in judgment? Who elected you to be the saviors of everybody's souls in Bomont?"
And who elected Rev. Moore? No music and no dancing is a very personal and very targeted crusade for him. The death of his son drives his fervor and his internal conflict makes him an interesting antagonist. He's sympathetic.
Anyway ... as to how I handle religious themes in my own work, I focus on the personal experience that the individual character is having. A character's expression of religion is just another externalization of what's going on inside. No different from a character's "voice". Granted, it much more potent than regionalisms or word choice. So I tread respectfully -- and I make for damn sure I know what I'm talking about. (i.e. Protestants don't believe in transubstantiation. That sort of thing.)
Religious values are not the same as "God". Religious values come from somewhere; are motivated by something. I think exploring such things is rather the point of storytelling.
