…[T]here must be a renewal of Christian education. The rejection of Christianity is due to various causes. But a very potent cause is simple ignorance. In countless cases, Christianity is rejected simply because men have not the slightest notion of what Christianity is. An outstanding fact of recent Church history is the appalling growth of ignorance in the Church. Various causes, no doubt, can be assigned for this lamentable development. The development is due partly to the general decline of education–at least so far as literature and history are concerned. The schools of the present day are being ruined by the absurd notion that education should follow the line of least resistance, and that something can be “drawn out” of the mind before anything is put in. They are also being ruined by an exaggerated emphasis on methodology at the expense of content and on what is materially useful at the expense of the high spiritual heritage of mankind. These lamentable tendencies, moreover, are in danger of being made permanent through the sinister extension of state control. But something more than the general decline in education is needed to account for the special growth of ignorance in the Church. The growth of ignorance in the Church is the logical and inevitable result of the false notion that Christianity is a life and not also a doctrine; if Christianity is not a doctrine then of course teaching is not necessary to Christianity. But whatever may be the causes for the growth of ignorance in the Church, the evil must be remedied. It must be remedied primarily by the renewal of Christian education in the family, but also by the use of whatever other educational agencies the Church can find. Christian education is the chief business of the hour for every earnest Christian man. Christianity cannot subsist unless men know what Christianity is; and the fair and logical thing is to learn what Christianity is, not from its opponents, but from those who themselves are Christians.That method of procedure would be the only fair method in the case of any movement. But it is still more in place in the case of a movement such as Christianity which has laid the foundation of all that we hold most dear. Men have abundant opportunity to-day to learn what can be said against Christianity, and it is only fair that they should also learn something about the thing that is being attacked.
