What is parish life was ordered by the liturgical calendar and not the school calendar?

One leader muses on what difference it might make in the life our parish is we intentionally planned parish activities according to the liturgical calendar instead of, as most places currently do, the school calendar.

Even if following her advice seems un-doable in a complete sense, are there perhaps some things you could be doing differently?  What do you think?
