Pope Francis has just renewed his passport. He paid the $55 required to renew the important document despite not needing it.
A Pope loses all ties to his nation of birth once elected. As a sovereign head of state, he has no need of a passport. However, Pope Francis decided to get his renewed to show that he is just like everyone else and to show that he is still part of his nation Argentina. This of course has sent great joy to his fellow Argentinians.
