The ‘C-9’ are nine cardinals from around the world who meet four times a year to advise the Pope. At the end of their most recent meeting they announced that he had summoned senior bishops from around the world to the Vatican to discuss the protection of minors. The heads of the national bishops' conferences will meet in February 2019 to try to come to grips with a spreading sexual abuse crisis in the USA, Chile, Australia, Germany, and elsewhere. It was recently revealed that 1,670 German priests had sexually abused 3,677 minors, mostly males, over a seventy-year period. A US grand jury found 301 priests in Pennsylvania guilty of sexually abusing minors over a similar period. In August, Italian archbishop Carlo Maria Viganò accused the Pope of knowing about sexual misconduct by a US cardinal and doing nothing about it.
