Pope on Chastity

“They are greatly deceived who, having underestimated or neglected those means which rise above nature, think that they can induce men by the use and discovery of the natural sciences, such as those of biology, the science of heredity and the like, to curb their natural desires. We do not say this in order to belittle those natural means which are not dishonest; for God is the Author of nature as well as of grace, and He has disposed the good things of both orders for the beneficial use of men. The faithful, therefore, can and ought to be assisted also by natural means. But they are mistaken who think that these means are able to establish chastity in the nuptial union, or that they are more effective than supernatural grace.”

“We take this opportunity to address those who are engaged in education and all those whose right and duty it is to provide for the common good of human society. We would call their attention to the need to create an atmosphere favorable to the growth of chastity so that true liberty may prevail over license and the norms of the moral law may be fully safeguarded. Everything therefore in the modern means of social communication which arouses men's baser passions and encourages low moral standards, as well as every obscenity in the written word and every form of indecency on the stage and screen, should be condemned publicly and unanimously by all those who have at heart the advance of civilization and the safeguarding of the outstanding values of the human spirit. It is quite absurd to defend this kind of depravity in the name of art or culture or by pleading the liberty which may be allowed in this field by the public authorities.”
