4 - True freedom of communication

But since the Church is the teacher of the doctrine which leads to salvation, and has all that is necessary for the attainment of holiness, She is exercising an inviolable right when She teaches what has been committed to Her by divine command. It ought to be the duty of all public officials to recognise this sacred right, with the result that She should be given ready access to those arts by which She may spread truth and virtue.

Indeed, all true and active sons of the Church, since they recognise the priceless gift of the Redemption, are bidden to ensure, to the extent of their power, that the Church may use these technical discoveries in so far as they may assist the sanctification of souls.

Yet when We assert and claim these rights for the Church, it is not Our desire to deny to the State the right of spreading by the same means, that news and those teachings which are really necessary or useful for the common good of human society.

And further, let it be permitted even to individual citizens - due regard being paid to actual circumstances and the safeguarding of principles which promote the common good - to contribute according to their capacity to the enriching and development of their own and others' intellectual and spiritual culture.
