Sadly, astonishingly, suicidally—pick your adverb—mainstream Protestants, Roman Catholics and not a few evangelicals have for decades neglected Christian education and nurture. They have all but given up on trying to pass on knowledge of the faith, and they have neglected the spiritual health of children, the young and not a few of the adults who give lip service to the idea of growth in knowledge and discipleship.
Craig Dykstra does not make the points that would give depth to those sweeping generalizations, though it would not have been hard to do so. Many divinity schools and theological seminaries have let their departments of education atrophy. Denominations do maintain departments for youth work and they publish elaborate and often sophisticated materials for Sunday and parochial schools. They attract tens of thousands of youths to summer assemblies. But few back these endeavors with original research.
