What's missinng

Mosaics don't scale our church walls anymore.
What is it that we're missing if not this?
We've let go of religious expression
because we have forgotten what it's for.
But if that's not what's missing,
then tell me, what is?
Religious expression in our schools - no more.
It's a thought tycoon that's itself religious.
I hope the students have learned their lesson.
Something underneath those who have the floor,
tells them to make their lessons
all but religious.
So what do you get when you take the human core
out of our textbooks and public places?
Economic and mental depression;
do we need to review the preconditions of war?
Where faith is not free to roam,
God spare me from what is.
