Pope Benedict XV: Indecency offends God

From the 1921 encyclical, Sacra Propediem, by Pope Benedict XV; more relevant than ever: 

Now there are two passions today dominant in the profound lawlessness of morals - an unlimited desire of riches and an insatiable thirst for pleasures. It is this which marks with a shameful stigma our epoch; whilst it goes ceaselessly from progress to progress in the order of all which touches the well-being and convenience of life, it seems that in the superior order of honesty and of moral rectitude a lamentable retrogression leads it back to the ignominies of ancient paganism. In that measure, in truth, wherein men lose sight of eternal goods which Heaven reserved for them, they permit themselves to be more taken in by the deceitful mirage of the ephemeral goods here below, and once their souls are turned down towards the earth, an easy descent leads them insensibly to relax themselves in virtue, to experience repugnance for spiritual things, and to relish nothing outside the seductions of pleasure. Hence the general situation which we note: with some the desire to acquire riches or to increase their patrimony knows no bounds; others no longer know, as formerly, how to bear the trials which are the usual result of want or poverty; and at the very hour in which the rivalries We have pointed out set by the ears the rich and the proletariat a great number seem to wish to further excite the hatred of the poor by an unbridled luxury which accompanies the most revolting corruption. From this point of view one cannot sufficiently deplore the blindness of so many women of every age and condition; made foolish by desire to please, they do not see to what a degree the indecency of their clothing shocks every honest man, and offends God. Most of them would formerly have blushed for those toilettes as for a grave fault against Christian modesty; now it does not suffice for them to exhibit them on the public thoroughfares; they do not fear to cross the threshold of the churches, to assist at the Holy sacrifice of the Mass, and even to bear the seducing food of shameful passions to the Eucharistic Table where one receives the heavenly Author of purity. And We speak not of those exotic and barbarous dances recently imported into fashionable circles, one more shocking than the other; one cannot imagine anything more suitable for banishing all the remains of modesty.
