Pope Piux XI on education
Hence every form of pedagogic naturalism which in any way excludes or weakens supernatural Christian formation in the teaching of youth, is false. Every method of education founded, wholly or in part, on the denial or forgetfulness of original sin and of grace, and relying on the sole powers of human nature, is unsound. Such, generally speaking, are those modern systems bearing various names which appeal to a pretended self-government and unrestrained freedom on the part of the child, and which diminish or even suppress the teacher's authority and action, attributing to the child an exclusive primacy of initiative, and an activity independent of any higher law, natural or divine, in the work of his education.
If any of these terms are used, less properly, to denote the necessity of a gradually more active cooperation on the part of the pupil in his own education; if the intention is to banish from education despotism and violence, which, by the way, just punishment is not, this would be correct, but in no way new. It would mean only what has been taught and reduced to practice by the Church in traditional Christian education, in imitation of the method employed by God Himself towards His creatures, of whom He demands active cooperation according to the nature of each; for His Wisdom "reacheth from end to end mightily and ordereth all things sweetly."
