I find that interesting because I disagree strongly. It is certainly true of some churches, but I wouldn't say majority—at least it would not characterize most of the churches I've been to. And certainly not what I would consider a more ideal "script" if you want one, which would be simply...

There is a place for "performed" music, just as there is a place for the "professional" sermon, each bringing to the service knowledge, skill, and experience above the level of most of the congregation.
