Imagine you could run the Catholic Church for a generation or so without any West-European cleric/priest/monk.
OK. Just imagine, the political branch runs, there is still a Vatican-state, the Church-buildings are being looked after and paid for by the governments, etc...
This will be the situation in 10-15 years.
The result will be that the South-Americans/Chinese/African/American Catholics would become the most powerful in this Church.
The Catholic Church would become totally alienated , totally un-European.
Besides : What is a Church, if it doesn't defend itself against Islam/Marxism from within?
It is doomed to perish.
What the result will be for Europe, I can predict as well:
There will be a civil war with non-europeans.
Suddenly the millions of Europeans will go back to the Catholic Church.
In times of war, people suddenly do care about God again....
And then what?
having african bishops , cardinals ,...
that's insane.
