Right now there is not even an hour of religious education on which parents can extend upon or even reinforce.  My kids would come back having learned essentially nothing,  because all of the social teaching that they were getting from their "teachers" was obvious to them because they were brought up with parents who had already taught them those things from birth.

The current generation of new parents are products of this post-V-II lack of education; even if their kids learned something about their religion, the parents would be unable to engage with them about it.

Our parish priest thanks the parents - almost begs them to come back - for bringing their kids to mass.  Unfortunately, he says nothing compelling during his homilies that would make those kids want to return on their own someday.  "Oh, you witnessed someone being nice to someone else the other day?  Wow, how great it is to be a Catholic."
