Did you read any of the information of subsidiarity?
yep. several of the articles. And what the pope is calling for is ANTI-subsidiarity. Using the force of the state to redistribute wealth is theft no matter what nice name you label it with.
The moment you involve the state, it becomes theft. If he wants to preach to the rich that they should share more, I'd be in total agreement. But that is not what he did. He called for the state to come in and FORCE them to share more.
Yossarian is right on in his comments.
