Hi Hector, I realise this article is about Pittsburgh  consolidations;  I know nothing about Pittsburg but I used to live in Boston where there have been similar closures/consolidations.  The reasons given are collapse in vocations and collapse in Mass attendance.  My contention is that both of these are in large part the result of the Bugnini-Montini liturgy.  Bill F has pointed out that there are many other variables involved—and if I am honest I have to admit that is true as well.  But alongside that is the incontrovertible fact that Mass attendance collapsed after introduction of the Novus Ordo.  Again, don’t confuse this with this vernacular-versus-Latin matter, which is another issue entirely, and a relatively minor one at that.
