5 To what and to how many snares are the souls of so many of Our sons submitted in those areas to make them reject the Faith of their fathers, and to make them break, most wretchedly, the bond of union which links them to this Apostolic See! Nor can We pass over in silence a new crime to which, with utmost sorrow, We want earnestly to draw not only your attention, but the attention of the clergy, of parents, and even of public authorities. We refer to the iniquitous campaign that the impious lead everywhere to harm the shining souls of children. Not even the age of innocence has been spared, for, alas, there are not lacking those who boldly dare to snatch from the mystical garden of the Church even the most beautiful flowers, which constitute the hope of religion and society. Considering this, one cannot be surprised if peoples groan under the weight of the Divine punishment, and live under the fear of even greater calamities.
