I’m in agreement will a lot of the other posters here. A centralized governing body would be detrimental. It’s been tried and has had less than stellar results.
the Mormons went so far as to say God and Jesus appeared and annointed thier prophet and his 12 apostles to prove they were that regulatory group on earth
every denomination wants that authority and many claim it already hence the divisions .there’s far too much division for it to ever work man is way to unreliable and way to divided in the present
