So no one's going to point out the obvious? If God wants the Pope to be sniped, the Pope will be sniped. If he has the power to do whatever the hell he wants whenever he wants, he can stop those people trying to get rid of his holy men. So, hiding behind 6 inches of bullet-proof glass is basically the Pope saying either "God MIGHT be pretty pissed at me right now" or "I don't have faith that God will protect his holiest man"
And if the Pope is thinking either of those things, what hope does anyone else have?
Not a question of faith, there are humans with and without faith, then there's the idiots that think they have something to prove OR they're high on some shit and would try to kill a religious figure. Faith or not, People are stupid, that's why there's protective glass.
