You have very intelligently elucidated the very real cause for the Catholic Monarchial state, and the sad disapperance of it thanks to American Imperialism in WWI, etc.
You comment about having a non elected king as sovereign is quite spot on.
One more very important point: in a monarchy there is no such thing as "politics" for the average man. He only needs to kn0ow one thing: "God save our Christian King!". Politics did not exists for the masses - and to a very great extent this was a good thing. Great things were left for great men to decide - and a king, historically, had to rule with equity. It was his duty, and what he was rasied to do. The state/monarch was to protect the comman man, so that he need only concern himself about living his life.....not how to fund mass transit! That was the job of hte king.
Since the dissolution of Western Monarachies over the past century man has experienced nothing but war and political madness and instability. to change the government every few years (i.e. US, Israel) is sheer madness. It by itself does nothing to contriubute to political stability, and peace of mind for the citizen.
A simple reality check would assure any American that his opinion does not count, and that there really is no such thing as representative government (at least not as it functions here at present).
Regardless of any good an noble intentions in the US Constitution, real political power is very far removed from the average man - he truly has no redress of greivances; merely the very flimsy apperance of the same.
The king - like a US President or any leader - only governed because the will of Christ allowed him to. No man has power, except it is allowed by Christ. The difference is that a king - unlike a US President - is crrowned by a bishop (or the Pope in former times), and pledges his service to his nation by an oath to Almighty God, ackknowledging that his power comes from above.
That's right -- it's all America's fault as always. I can see you guys are great readers of Noam Chomsky, Michael Moore, Moveon.org and all the other professional blame America first, America is the source of all the evil in the world crowd -- you follow exactly the same playbook. Wonderful to have such loyal, patriotic people as yourselves -- loyal neither to Pope nor Country.
Thank you for your comments. It is Catholics like you who make me want to join the Church. (I'm not quite there yet, but the local trads are working on me!)
