Pope Benedict XVI’s resignation was certainly sudden but not altogether unexpected. During the pontificate of his predecessor, the then Cardinal Ratzinger seems to have advised the long-suffering Pope John Paul II to renounce the Petrine office. Crucially, in mid-2010 Benedict gave a strong indication that he was considering abdicating. On April 29, 2009, he left his pallium—the sign of Episcopal authority—on the tomb of Pope Celestine V in the Basilica Santa Maria di Collemaggio, in L’Aquila. In the same location Celestine had been crowned pontiff on August 29, 1294—an event that is commemorated as the festival of Perdonanza Celestinana in the earthquake-stricken city every August 28–29. It is unlikely that Benedict’s highly symbolic gesture was a random act. Clearly he felt a deep spiritual connection with the studious monk-pope Celestine, who abdicated in 1295.
