Actually, that’s what I thought the Church did every chance it had.
I suppose if the priest cares at all what happens to the children, he would have taught not just philosophy, but theology, mathematics, literacy, science, ethics and a whole host of other subjects and skills.
If human development or enrichment – in all its virtuous aspects: emotional, intellectual, physical, psychological, spiritual – has anything at all to do with salvation, then any caring priest would promote education as part of what it means to become more fully human.
I suspect we have two very different ideas about what salvation entails.
You appear to suppose it is transformation into some unearthly state completely detached from what it means to be human at all, thus any current state is irrelevant to one’s salvation.
My impression is that grace perfects nature, so salvation follows a trajectory from birth to fully human to supernatural existence. Grace perfecting nature through the development of both natural and supernatural virtues – rather than voiding or nullifying nature – is the way I understand the meaning of salvation.
