It has become fashionable for church bureaucrats to instruct pastors with whom they have to do that while whacky, out-of-touch, loony "liberals" with their antichristian agendas are certainly not to be tolerated, there are also those who are too far out on the other side. The implication is that the middle is golden.
This is certainly true of some things. But the fact that it is gives no license for the maxim to be applied to all things.
There are not always two fringes.
Are we to say that someone who is way out on the 'no-integrity' fringe is no worse than someone who is way out on the 'too-much-integrity' fringe? Or what of someone who lies all the time. The other fringe would be someone who is too truthful. The reductio ad absurdem is not too hard to find.
So too, while there is certainly a too-loose fringe in matters of worship, that is, a kind of worship in which anything goes, and in which therefore everything becomes objectionable for those who truly want Christian worship, must there necessarily be a corresponding too-rigid fringe? "Rigid" of course is a nasty term by which bureaucrats like to refer to liturgists who take matters of worship with all gravity and seriousness. But is there a too-tight fringe? Actually if it be a truly opposite fringe to one that is too "loose," we must define "loose." I rather think it means casual, or lacking formality. But what's formality in worship? Is it not synonymous with reverence? Can one be too reverent? Ah, that is the real matter. Too reverent?
As in, have we shown Christ (whom we believe to be present) too much deference? Too much adoration? Too much worship?
I'm not sure the reference to the lukewarm in the Apocalypse is meant to apply to this, but I'd say it sort of fits. Sometimes the middle is not so golden.
