Whilst not directly answering your question (I hope you’ll excuse me for that

), here are a few personal observations.
I am from Armagh, the Ecclesiatical capital of Ireland. I went to a Catholic primary school, and the Grammar School which sits alongside the Cathedral. An upbringing of complete catholicism, one would think.
Yet, despite the obediance and committment to the faith by my parents, I can’t help but feel that I’ve grown up in a Catholic community which doesn’t really know why it’s Catholic - at least amongst the younger generation. There are young people who attend Mass (although it is certainly an older congregation), but given my experiences at grammar school (a school which apparently prided itself on it’s committment to the faith), I felt spiritually malnurished. Similarly, I feel that that the Church itself had failed to offer sufficient teaching to the people of the parish.
It was only when I reached university that I was finally able to learn about the faith - in an open and voluntary environment, through our chaplain who genuinely knew how to reach out to the student generation and enlighten them in the faith. I shall forever be thankful to him for offering this, and providing catechesis courses and other programmes - an area where I certainly feel my parish has failed.
So, how this relates to the thread. Well, an uneducated youth means a definite difficulty in vocations, and whilst it is certainly a personal committment to the faith that is required, I feel that the Church needs to do much more work with parishioners. Something which I may just contact our new Cardinal with regard to.
