"A thick smell hung over the entire Peloponnesus..."
King Augeas owned many herds of cattle, but his stables had never been mucked out. When Hercules was punished, one of the twelve labors he had to perform was to clean the Augean stables in a single day. He surprised everyone by diverting the neighboring river -- and the barns were washed out to a fare-thee-well.
The corruption and cover-up of Catholic priests in Philadelphia has been massive. By not being vigilant guardians of the apostolic band of men under their charge -- allowing scoundrels, predators, and she-dogs to be ordained and then giving them free rein -- the Philly archbishops quenched the Holy Spirit.
Cardinal Krol (whose parents were Polish immigrants) was in charge from 1961-1988. Then, Cardinal Bevilacqua (son of Italian immigrants) took over until his resignation in 2003.
Thus it falls to Archbishop Chaput to whip things into shape in Philadelphia. Holy Spirit, give him resolve and let your cleansing River flow!
