The oceans roar, the stars explode
For you my maker, saviour,
You're all-mighty G-d

I think it's all right, but that's just me. I'd say the topic is definitely under-researched
A quick search for "religion" and "prayer"

PS
SBNR stands for "Super Bloated, Nears Rupturing".
A few funny folks pretend it's "spiritual but not religious" - don't believe them.
I can't claim to know what SBNR is, but to answer your question, no, I haven't thought about using religion in any of my stories, not even the handful or so I'm currently thinking about writing. I guess, if I had to, I would do something in the form you mentioned, some made up religion that incorporates inflation into their practices or rituals.
I honestly don't think there are any limitations, at least not regarding this I would see an issue with. Sure, some people might get upset, but people get upset about anything these days, I don't see any major issues with using a made up religion in a story, heck, could even make some of it make sense, that it's a practice that dates back hundreds or thousands of years, there's no real reason people are doing it, it's just what they've always done.
