Churches use music. Some of them have pretty advanced setups with dozens of microphones for the choir, speeches and instruments, all of which is mixed down and send to a speaker setup that has to cover weird acoustic rooms and also transmitted by radio to people with hearing aids etc. Organists also use some wild midi setups at home for practicing. A surprisingly big part of free VSTs are made for that specific purpose.

I don’t really like religion or churches, but I have massive respect for their audio guys who sets up the equivalent of a big stadium concert every Sunday using hand downs from the thrift store and free software.
