The entire concept falls flat on its face the second you want to write an intra-family conflict that lasts more than the run time of an episode. It's a concept we've discussed in my writing group. If you're going to be episodic, your characters need to be kind of 2 dimensional. Since I don't read enough, I think of Family Guy where Lois gets a job at the news and when asked about how she lost the job at the end, she replies "does anyone really care?"

Well, since you're a hog and your brain doesn't really do lateral thinking, non-negotiably you want the themes of the show to reflect some kind of rejection of modern culture. "I mean it, this shit around me is not Christcore." You might get through 2 seasons, an introduction to the family and a drawn out conflict with a trans school principal or something. Well, eventually your audience is going to ask how the family deals with a child losing faith or martial issues. The shit will turn into pure ideology. The resolution will be unhelpful because when the wife decides to trust the husband because of a vision from God and the real life woman cannot square the circle of someone fucked up on their vice of choice because they're both evermore atomized. The show will show its thin veneer of aesthetic.

It would only be dogma that Christians I know don't even do. Shows in that position, at best, turn into camp and dumb down their characters. Like one of the kids becomes an atheist for 5 episodes, gets really into anime, and the mangaka of his favorite series is Christian so he converts back. Otherwise they get weird and probably double down on transphobia or something.
