Living near Levada's diocese is no fun. However, I do know that the priests in his diocese are sick of all of the trips he has taken to Rome over the years. They say that he has campaigned for a high curial position for years. I pray that he doesn't get one.
Where does this "errand boy for the Pope" bit come from. I have never seen any evidence of this.
He had done precious little to clean up his own Archdiocese. Even Cdl. McCarrick has done better in terms of church docitrine in the DC archdiocese than Abp. Levada has done in his, not to mention priestly vocations. If Abp. Levada cant control his own archdiocese, he can he function as head of the CDF?
