This is exactly, precisely right. Exactly, precisely right. Even "canonically" right. I mean right all the way through.
That's why, for example, the USCCB should be disbanded. The "political policy" part has largely cannibalized the rest of it, and it's a particularly irksome form of clericalism.
There shouldn’t be anything wrong with a group of bishops dealing with challenges to Christian faith that pop up in their country. But I agree, the political pronouncements almost turn it into a circus. And it would irk me as much if, say, the SBC got topheavy about this. I’d take that as a sign that there was too little activity at the lay level.
Let the church do Christianity well, and the salt and light will pour out. Like a hymn (which I don’t know whether it’s current in Catholic circles, but they do borrow from evangelical Christendom) goes — let the lower lights be burning, send a gleam across the wave, some poor fainting, sinking sailor you may rescue, you may save.
