Pope Benedict XVI stunned the world when he announced his resignation in 2013, the first in 600 years. That led some to wonder if, as he grew increasingly frail and sick, Pope Francis would follow that precedent.
While Francis kept open the possibility, and even had a resignation letter prepared, he said more recently that he believed that the papacy was for life. And he ultimately lived out that belief, serving in his ministry until his death on Monday, at the age of 88.
