Modesty does not change over time. Modesty has absolute standards that never change. Just like other aspects of moral truth.
Some material for thought to show how modesty is part of the Faith:
“Fashions will much offend Our Lord. People who serve God should not follow fashions. The Church has no fashions. Our Lord is always the same.”
Bl. Jacinta of Fatima
I quote saints, it generally takes longer than 20 years to canonize. But the saints say the same thing from 100 A.D. to 1000 A.D. to today.
Modesty does not change.
They also say that few people go to Heaven. Repeating the scriptures repeated admonishment. That Christians must be different from people of the world.
‘But how can you know anything of the impression made on others? Who can assure you that others do not draw therefrom incentives to evil? You do not know the depths of human frailty. . . Oh, how truly was it said that if some Christian women could only suspect the temptations and falls they cause in others with modes of dress and familiarity in behavior, which they unthinkingly consider as of no importance, they would be shocked by the responsibility which is theirs.’
Pope Pius XII
‘The good of our soul is more important than that of our body; and we have to prefer the spiritual welfare of our neighbor to our bodily comforts. . . If a certain kind of dress constitutes a grave and proximate occasion of sin, and endangers the salvation of your soul and others,
it is your duty to give it up.’
Pope Pius XII
‘What is it all for? If they only knew what eternity is.’
Bl. Jacinta Marto of Fatima, age 9, on seeing immodest and fashionably dressed women
‘Let parents keep their daughters away from public gymnastic games and contests; but if their daughters are compelled to attend such exhibitions, let them see that they are fully and modestly dressed. Let them never permit their daughters to appear in immodest dress.’
Decree of the Congregation of the Council (by the mandate of Pope Pius XI), 1930 A.D.
Signs on the doors of San Giovanni Rotondo:
“The Church is the house of God. It is forbidden for men to enter with bare arms or in shorts. It is forbidden for women to enter in trousers, without a veil on their head, in short clothing, low necklines, sleeveless or immodest dresses.”
“By Padre Pio’s explicit wish, women must enter the confessional wearing skirts AT LEAST 8 INCHES BELOW THE KNEE. It is forbidden to borrow longer dresses in church and to wear them to confession.”
‘A dress cannot be called decent which is cut deeper than two fingers breadth under the pit of the throat; which does not cover the arms at least to the elbows; and scarcely reaches a bit beyond the knees. Furthermore, dresses of transparent materials are improper.’
The Cardinal Vicar of Pius XI
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 outfits 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 these 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.
Pope Benedict XV
‘We must practice modesty, not only in our looks, but also in our whole deportment, and particularly in our dress, our walk, our conversation, and all similar actions.’
St. Alphonsus Maria de Liguori, Doctor of the Church
'You carry your snare everywhere and spread your nets in all places. You allege that you never invited others to sin. You did not, indeed, by your words, but you have done so by your dress and your deportment. . . When you have made another sin in his heart, how can you be innocent? Tell me, whom does this world condemn? Whom do judges punish? Those who drink poison or those who prepare it and administer the fatal potion?
You have prepared the abominable cup, you have given the death dealing drink, and you are more criminal than are those who poison the body; you murder not the body but the soul.
And it is not to enemies you do this, nor are you urged on by any imaginary necessity, nor provoked by injury, but out of foolish vanity and pride.’
St. John Chrysostom, Father and Doctor of the Church
