Here is a fair question for you. What would it take to show you that the Roman Catholic institution is thoroughly corrupt? How about the Pope praising Islam and bowing to Mecca? Or the Pope kissing the Koran? Pedophile priests going after little kids? What?
What would it take to show you that EVERY institution human beings inhabit is thoroughly corrupt?
Funny, for folks who preach "total depravity" you act like "total" really means "highly selective and not on my street".
The Church is not the Mystical Body of the pope; it is the Mystical Body of Christ.
The really important and really interesting people in Catholicism are not the priests, or even the popes, but the saints.
