Except he's walked this walk for many years. It's being publicized now because he's the Pope, but by all accounts this is merely consistent with the way he's acted his whole life as a priest.
“Except he’s walked this walk for many years.”
Someone once said “Being humble isn’t thinking less of yourself, but more of others.”
Seems that by being more “in the world” in the cafeteria, Mass with the kitchen help, etc. he is in a position to reach out to others more.
