It’s worth your time to digest this. This is John Milton Gregory from his The Seven Laws of Teaching quoted in a review by Puritanism Today:
“In an age of cultural rootlessness, moral relativism, religious pluralism, social disintegration, and future uncertainty, how can we expect anything other than education chaos? Unstable times call for a return to theological foundations and historical forms. Many Christians mistakenly think the cultural and social mores of the 1950s provide the answers. But the families, churches, and schools of the 1950s produced the 1960s. The rediscovery of theological foundations and historical forms must go further back in history.
The theological foundations must be established upon the Scriptures. In education, Christians have too often seen the Bible either as a book to be studied in a separate subject, i.e. Bible class, or as a devotional book. Christian education must teach not only Bible details, but Biblical systematic theology. From that theology, Christians must develop a worldview that applies Biblical concepts to every area of life. Thankfully, this has been done numerous times in the history of Christianity. The historic forms or examples can be found where Christians produced educated, Biblically literate, discerning students. The historic form can be called Classical Christian Education.”
