"Francis praised his longtime ally and suggested Wuerl had unfairly become a scapegoat, having made some mistakes in handling sex abuse cases, but not having covered them up."
That's a fairly stupid gif. The church has never claimed that she "does not make mistakes". There were Popes who were slaveholders and others who condemned slavery. (You can put "Presidents" in that sentence and it works also.)
As for the Holocaust, Pope Pius XII saved 860,000 Jewish lives. Show me another organization that did as much.
