FWIW, what does 210.70 (c) have to do with egress lighting?
Nothing, but felt it was worth mentioning considering its the only section of the NEC for lighting requirements in non-dwelling occupancies such as churches.
I do agree that the local AHJ needs to be consulted. Some aspects of religious occupancies are exempt from building code and accessibility issues.
At least, that is the way it is here in Florida.
