At a certain point you have some blame for the AHJ. This is clearly a 680 regulated "pool" and it should have been inspected to that standard. Unfortunately I also understand churches are the worst about using unqualified (volunteer) labor and working without permit/inspection overview.
My question would be, was this a listed pool/spa heater or just something cobbled up from water heater elements. How was it bonded? Was the audio system tied into the same bonding grid?
