'Levada is upset that Pentecostalists are teaching Catholics that they are going to hell if they don't convert.'
The answer is conversion but not Evangelicalism/Pentacostalism, but to Catholicism. So many in the pews are only warming them and have no concept as to what the faith teaches, before or after V2. The problem is not with the mass being in the vernacular, the problem is with the liberal, watered down Catechesis and preaching that has been and is being taught. V2 may well have opened that door, but a fair number have walked through it and the Church is paying the price now. I know, I was a victim of the watered down Catechesis taught in the 1960's and 1970's. I was a public schooler, and I've seen noithing to convince me it was any better for my Catholic School educated peers. Only recently has the beauty of all She teaches and her positions on all matters down through the ages been brought to the forefront of my awareness.
We have to get back to authentic Catholic teaching. We can't keep watering down the faith and expect better, more faithful Catholics to result from it.
Millions of Catholics apostacized pre-Vatican II in America, especially in the period 1880 to 1940. You can do the math easily by adding up the numbers of people of Irish/Italian/Polish/Hispanic/French/Lithuanian/Czech/Austrian/etc. descent and comparing that to the Catholic population. That is how you have oddities today like 3rd generation Irish Baptists, Italian Methodists, Ruthenian Orthodox, and Hispanic Evangelicals. Its not like all these people weren't Catholics back when they came here.
Catechesis in America appears to have been in a permanent crisis at least since the early 1800's.
