Why does the Pope need security? Aren't the prayers of the faithful enough?

While I'm glad nothing happened to the Pope on a personal level, logically, they should get rid of security and let faith handle it. It would be like putting his money where his mouth is. If God wants a Pope, he'll provide one, right?

Father Federico Lombardi, the pope's spokesman, said it's not realistic to think the Vatican can ensure 100% security for the pontiff because he is regularly surrounded by tens of thousands of people for his weekly audiences, services, papal greetings and other events.

"It seems that they intervened at the earliest possible moment in a situation in which 'zero risk' cannot be achieved," he said of Vatican security officials. They will nonetheless review the episode and "try to learn from experience," Lombardi said.
