Separation or Unification of Religion and Education?

The most difficult problem appears quite trivial. That is, do we and can we maintain the separation of civic education (religion) and economic education (the grammars of calculation), and craftshmanship (the trades), or do we restore the relationship beween civic education, economic eductaion, and craftsmanship? Because this turns out to be a rather difficult problem of converting the church, or converting the academy.
