Ubi Arcano Dei Consilio §14

¹⁴ Just as the smallest part of the body feels the effect of an illness which is ravaging the whole body or one of its vital organs, so the evils now besetting society and the family afflict even individuals. In particular, We cannot but lament the morbid restlessness which has spread among people of every age and condition in life, the general spirit of insubordination and the refusal to live up to one's obligations which has become so widespread as almost to appear the customary mode of living. We lament, too, the destruction of purity among women and young girls as is evidenced by the increasing immodesty of their dress and conversation and by their participation in shameful dances, which sins are made the more heinous by the vaunting in the faces of people less fortunate than themselves their luxurious mode of life. Finally, We cannot but grieve over the great increase in the number of what might be called social misfits who almost inevitably end by joining the ranks of those malcontents who continually agitate against all order, be it public or private.
