I keep hearing about religious exemption, but was curious as to the specifics of it. What if they don't formally belong to a church group? Do they have to formally join a denomination which has done some sort of official paperwork for it be grounds for exemption in a legal sense? Or do we simply state it on whatever paper is given to us with a bible verse? etc. I have no idea how this is supposed to work. I'm not at that point yet, but should it happen tomorrow, next week, month, etc I'd like to have a better idea.

Have anyone of you hear already done this? What exactly did you have to do, etc? It doesn't have to be for covid either. It could be for something else, as this isn't the first time religious exemption has been needed.

Specifically in the context of a workplace. It could be public sector or private company.
