76 This educational environment of the Church embraces the Sacraments, divinely efficacious means of grace, the sacred ritual, so wonderfully instructive, and the material fabric of her churches, whose liturgy and art have an immense educational value; but it also includes the great number and variety of schools, associations and institutions of all kinds, established for the training of youth in Christian piety, together with literature and the sciences, not omitting recreation and physical culture. And in this inexhaustible fecundity of educational works, how marvelous, how incomparable is the Church's maternal providence! So admirable too is the harmony which she maintains with the Christian family, that the Church and the family may be said to constitute together one and the same temple of Christian education.
