Those rivalries came to the fore last year with the leaks of internal papal documents by the pope's own butler. The documentation revealed bitter infighting within the highest ranks of the Catholic Church, along with allegations of corruption and mismanagement of the Holy See's affairs.
Benedict took the scandal as a personal betrayal and a wound on the entire church. In a sign of his desire to get to the bottom of the leaks, he appointed a commission of cardinals to investigate alongside Vatican investigators.
His butler, Paolo Gabriele, was convicted and sentenced to 18 months in prison, although Benedict ultimately pardoned him.
