If a protestant disagrees with those higher powers, then he can always switch Churches. If a Catholic disagrees with the Magisterium, he goes to hell.
We protestants are free to criticize our own churches and everyone else's. Catholics are limited to criticizing everyone else's. As shown by the article above, they are pretty adept at it. Refusing, despite all biblical evidence, to see the heresy in their own church, but eager to point out any perceived heresy in every other church.
But I digress.
Good points.
But I think those are points that Holy Spirit has to make real for folks.
Human argument can be used of Holy Spirit to do that—but usually long after the fact in private spaces and places.
