72 And since from so many prayers We must hope for everything, and since everything is possible to that God who has promised everything in answer to prayer, We have confident hope that He will illumine men's minds with truth and will turn their wills to good, so that the Church of God, which wishes to take nothing from the State of that which belongs to the competence of the State, will cease to be asked for that which is of the Church's competence - the education and the Christian formation of youth, as this is Hers, not through human favour, but by divine mandate. She must always claim it with an insistence and an intransigence which cannot cease or waver, because it does not come from human desire or design or from human ideas changeable in different times and places and circumstances, but from the divine and inviolable decree. And we are inspired also by faith and confidence to believe that good will undoubtedly come from the recognition of such a truth and of such a right.
