Perhaps. But maybe not in the way you think.
Our parish is among the most orthodox in the diocese (or was...we have a new priest now and I'm still forming an opinion about him). It's small, but we currently have three young men studying for the priesthood and several others thinking about it. That's way more than any other parish in the state, the big towns included. And that seems to be true in a lot of places - the more traditional parishes are flourishing...the ones that cater to popular culture are not.
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.
,,, no, it won't. Generations have been used to altar boys serving. Girls always knew that task wasn't open to them just as I knew I'd never be able to land a job in a lingerie shop, despite my desperate continued pleas for inclusion. What Catholics should expect now is a tightening up in traditional routines, a sense of realignment and direction not a departure to letting pillow biting bishops call the shots as the Anglicans are doing.
I completely agree with those on this thread who have said that the Church will have to sort out the sexual molestation fiascos of the past. That behaviour cannot continue if the Church wants growth in the light of crediblity. Those who have let such things happen should be held accountable for certain.
