" Classical education was only half the old system of European education--below it and above it there was the religious education that was common to the whole people, and the higher theological education that was peculiar to the clergy, who provided the majority of the teachers in both the other departments of education.

Now the lowest level of this structure, which has been least studied and least regarded, was the most important of them all. It is true that it differed considerably in different parts of Europe, but for the religious rather than material reasons. In Protestant Europe it was founded on the Bible and the catechism, whereas in Catholic Europe it was based on the liturgy and on religious art and drama and mime, which made the Church the school of the people. But in either case it provided a system of common beliefs and moral standards, as well as the archetypal patterns of world history and sacred story which formed the background of their spiritual world.
