Why would you use a study from a non-Catholic College like Georgetown to measure Catholic Church attendance?
I was wondering the same thing. In California, the Masses are JAMMED-PACKED each Sunday; all the Missions; all the Churches seem to be doing very well, but I don't know of anyone who quantifies attendance.
..........and, in Cairo and in Beijing - standing room ONLY at the Catholic Churches if you get there too late.
A beautiful thing.......
