I speak for italy, and italy alone, since we’re in a peculiar situation when it comes to the Catholic church.
Our nation is theoretically independent from the church, and the church itself refuses any interference from our government, the opposite is not true, however, since popes, cardinals, bishops, priests, flying nuns and their vibrators, seem to all have an opinion on what the state should do, and think you desperately want to hear what a bunch of sociopaths, that had to close themselves out of the real world in order to live what they consider a good life, have to say about the real world.
As for the actual question: no they don’t, and yet they do. Cardinals and bishops are not going to speak out on pretty much anything themselves, because all those who would listen to them already hear whatever they have to say at their local church every sunday.
Besides since they reached that high up in the hierarchy, they’re just going to parrot the official positin of the church with varied degrees of severity or lack thereof, just to give the impression that the church is not some gigantic colossus only interested in gathering followers to make more money.
