John Milton described Christian education by way of the telos, or the purpose of education. Today we seem to have reduced Christian education to mean the same thing that secular education means except with prayer and Bible reading.
Secular education plus Bible and prayer does not make Christian education, but sets up false dichotomies in the minds of our children. The realm of education cannot be removed from the idea of submission to God. Education needs to reflect our faith and our deepest core values.
The end then of learning is to repair the ruins of our first parents by regaining to know God aright, and out of that knowledge to love him, to imitate him, and to be like him.
-John Milton, Of Education, 1644
