Three people accused of stealing and leaking secret papers are currently on trial at the Vatican, along with two journalists accused of publishing the documents, which depict irregularities and extravagance in the Holy See's spending.
The year has also been marked by rumors appearing to originate within the Church of the pope's ill health, allegations of clerical sex abuse, stories of wild parties in the Vatican and charity money being spent on a cardinal's apartment.
Francis offered his unruly flock a "catalogue of needed virtues" for those who serve in the Curia – a 12-point "practical aid" of guidelines including "setting an example" for the faithful and being honest, charitable and humble.
