I don't know... "minister? should we all be claiming this title?
We've had some sound system problems, and the techie who came out to look at it wanted to know who the "minister of Sound" was and if he would be there for the consultation.
Wikipedia, NOT NECESSARILY CORRECT BUT arbiter of common knowledge, and the commonly accepted says that, "that in Christian churches, a minister is someone who is authorized by a church or religious organization to perform clergy functions such as teaching of beliefs; performing services such as weddings, baptisms or funerals; or otherwise providing spiritual guidance to the community."
I hereby announce myself over buzzwording terms that, in the conduct of our faith life demand to be used with more precision.
