Where will they get Latin teachers from?
Could it be really just a way of getting priests/nuns more hours in schools? Still, it's hard to see where they're going to find qualified teachers of Latin to turn up for a handful of hours a week.
I remember my Latin classes at university
Mine were actually quite good fun, because the guy teaching it knew how to make it interesting. He also understood that most people just wanted to get a pass and go away, so his condition of passing was that you had to attend and take part in the classes/exercises, but then the "final exam" consisted of turning up and having a chat with him about what you'd learnt during it.
