IMHO, they will never address the vocations issue without making Catholic education available to more young people. In my area so many of the schools are closed, and CCD is a poor substitute.
Altar girls are a disaster; beyond dangling the false promise of priestesses in front of these young girls, the implementation was ridiculous: Each ordinary would decide whether or not his diocese would have them. How can a new bishop “undo” them when his predecessor implemented them? (Obviously they can’t/won’t...)
One of the churches in my vicariate has only altar boys. And you guessed right, they also have an ordination of someone from their parish nearly every year.
Proof of the pudding!
CCD is impossible, we get them for an hour and 15 minutes after a long day at school and we don’t have it in the summer.
