VATICAN CITY — Pope Francis came to power promising not only to create a more inclusive church and to clean up an ossified Vatican bureaucracy, but also to remove the stain of child sex abuse.

A global pedophilia scandal plagued his two immediate predecessors. With Francis’s election in 2013, many expected progress. Francis talked about powerful committees to safeguard children, tribunals to try bishops and a “zero tolerance” policy for offending priests.

It hasn’t exactly worked out that way.

On Thursday, the Vatican announced that Francis had granted a leave of absence to Cardinal George Pell, now the highest-ranking Roman Catholic prelate to be formally charged with sexual offenses, and one the pope had brought into his inner circle even as a cloud of allegations swirled over the cardinal in Australia.

“We talked about my need to take leave to clear my name,” Cardinal Pell, 76, stone-faced in simple black cleric’s clothes, said as he sat next to the Vatican’s spokesman and reiterated his innocence. “So I’m very grateful to the Holy Father for giving me this leave to return to Australia.”
