The proof is already here.
The only Catholic parishes that are both gaining in numbers and producing new vocations are conservative parishes where altar girls are unknown.
This is not a well-kept secret - there are reasons why conservative dioceses like Lincoln, NE - with one-twentieth the Catholic population of liberal Chicago - have forty times as many seminarians than places like Chicago where altar girls are common.
Radical feminism doesn't play in Catholic city.
That's not true, of course, but why not just issue sweeping generalizations to back up your point of view?
Female altar servers are a sideshow in this document.
What this article doesn't reveal is that there are also proposed restrictions on communion in the hand and under both kinds, both of which would never fly in the United States.
It's obvious that a coterie of reactionaries decided to issue a trial balloon, and it is quickly losing air, as bishops and cardinals, in other versions of this article, have said "these will never be accepted."
Trying to restrict quotations in homilies to Scripture alone? How silly. Bishop Fulton Sheen wouldn't have been able to give half the homilies he did, as he liberally quoted Shakespeare, and Chesterton, and Hammersjkold, and even Popes!
Or banning clapping for a newly baptized baby or new confirmand, or when the Pope processes in at Mass? Ludicrous.
What are these dolts thinking?
