Humanae Vitae - Encyclical Letter of His Holiness Paul VI on the regulation of birth

by Paul VI

  If therefore there are well-grounded reasons for spacing births, arising from the physical or psychological condition of husband or wife, or from external circumstances, the Church teaches that married people may then take advantage of the natural cycles immanent in the reproductive system and engage in marital intercourse only during those times that are infertile, thus controlling birth in a way which does not in the least offend the moral principles which We have just explained. (20)

  Neither the Church nor her doctrine is inconsistent when she considers it lawful for married people to take advantage of the infertile period but condemns as always unlawful the use of means which directly prevent conception, even when the reasons given for the later practice may appear to be upright and serious. In reality, these two cases are completely different. In the former the married couple rightly use a faculty provided them by nature. In the later they obstruct the natural development of the generative process. It cannot be denied that in each case the married couple, for acceptable reasons, are both perfectly clear in their intention to avoid children and wish to make sure that none will result. But it is equally true that it is exclusively in the former case that husband and wife are ready to abstain from intercourse during the fertile period as often as for reasonable motives the birth of another child is not desirable. And when the infertile period recurs, they use their married intimacy to express their mutual love and safeguard their fidelity toward one another. In doing this they certainly give proof of a true and authentic love.

  Consequences of Artificial Methods

  17. Responsible men can become more deeply convinced of the truth of the doctrine laid down by the Church on this issue if they reflect on the consequences of methods and plans for artificial birth control. Let them first consider how easily this course of action could open wide the way for marital infidelity and a general lowering of moral standards. Not much experience is needed to be fully aware of human weakness and to understand that human beings—and especially the young, who are so exposed to temptation—need incentives to keep the moral law, and it is an evil thing to make it easy for them to break that law. Another effect that gives cause for alarm is that a man who grows accustomed to the use of contraceptive methods may forget the reverence due to a woman, and, disregarding her physical and emotional equilibrium, reduce her to being a mere instrument for the satisfaction of his own desires, no longer considering her as his partner whom he should surround with care and affection.

  Finally, careful consideration should be given to the danger of this power passing into the hands of those public authorities who care little for the precepts of the moral law. Who will blame a government which in its attempt to resolve the problems affecting an entire country resorts to the same measures as are regarded as lawful by married people in the solution of a particular family difficulty? Who will prevent public authorities from favoring those contraceptive methods which they consider more effective? Should they regard this as necessary, they may even impose their use on everyone. It could well happen, therefore, that when people, either individually or in family or social life, experience the inherent difficulties of the divine law and are determined to avoid them, they may give into the hands of public authorities the power to intervene in the most personal and intimate responsibility of husband and wife.

  Limits to Man's Power

  Consequently, unless we are willing that the responsibility of procreating life should be left to the arbitrary decision of men, we must accept that there are certain limits, beyond which it is wrong to go, to the power of man over his own body and its natural functions—limits, let it be said, which no one, whether as a private individual or as a public authority, can lawfully exceed. These limits are expressly imposed because of the reverence due to the whole human organism and its natural functions, in the light of the principles We stated earlier, and in accordance with a correct understanding of the "principle of totality" enunciated by Our predecessor Pope Pius XII. (21)

  Concern of the Church

  18. It is to be anticipated that perhaps not everyone will easily accept this particular teaching. There is too much clamorous outcry against the voice of the Church, and this is intensified by modern means of communication. But it comes as no surprise to the Church that she, no less than her divine Founder, is destined to be a "sign of contradiction." (22) She does not, because of this, evade the duty imposed on her of proclaiming humbly but firmly the entire moral law, both natural and evangelical.

  Since the Church did not make either of these laws, she cannot be their arbiter—only their guardian and interpreter. It could never be right for her to declare lawful what is in fact unlawful, since that, by its very nature, is always opposed to the true good of man.

  In preserving intact the whole moral law of marriage, the Church is convinced that she is contributing to the creation of a truly human civilization. She urges man not to betray his personal responsibilities by putting all his faith in technical expedients. In this way she defends the dignity of husband and wife. This course of action shows that the Church, loyal to the example and teaching of the divine Savior, is sincere and unselfish in her regard for men whom she strives to help even now during this earthly pilgrimage "to share God's life as sons of the living God, the Father of all men." (23)

  III. PASTORAL DIRECTIVES

  19. Our words would not be an adequate expression of the thought and solicitude of the Church, Mother and Teacher of all peoples, if, after having recalled men to the observance and respect of the divine law regarding matrimony, they did not also support mankind in the honest regulation of birth amid the difficult conditions which today afflict families and peoples. The Church, in fact, cannot act differently toward men than did the Redeemer. She knows their weaknesses, she has compassion on the multitude, she welcomes sinners. But at the same time she cannot do otherwise than teach the law. For it is in fact the law of human life restored to its native truth and guided by the Spirit of God. (24) Observing the Divine Law.

  20. The teaching of the Church regarding the proper regulation of birth is a promulgation of the law of God Himself. And yet there is no doubt that to many it will appear not merely difficult but even impossible to observe. Now it is true that like all good things which are outstanding for their nobility and for the benefits which they confer on men, so this law demands from individual men and women, from families and from human society, a resolute purpose and great endurance. Indeed it cannot be observed unless God comes to their help with the grace by which the goodwill of men is sustained and strengthened. But to those who consider this matter diligently it will indeed be evident that this endurance enhances man's dignity and confers benefits on human society.

  Value of Self-Discipline

  21. The right and lawful ordering of birth demands, first of all, that spouses fully recognize and value the true blessings of family life and that they acquire complete mastery over themselves and their emotions. For if with the aid of reason and of free will they are to control their natural drives, there can be no doubt at all of the need for self-denial. Only then will the expression of love, essential to married life, conform to right order. This is especially clear in the practice of periodic continence. Self-discipline of this kind is a shining witness to the chastity of husband and wife and, far from being a hindrance to their love of one another, transforms it by giving it a more truly human character. And if this self-discipline does demand that they persevere in their purpose and efforts, it has at the same time the salutary effect of enabling husband and wife to develop to their personalities and to be enriched with spiritual blessings. For it brings to family life abundant fruits of tranquility and peace. It helps in solving difficulties of other kinds. It fosters in husband and wife thoughtfulness and loving consideration for one another. It helps them to repel inordinate self-love, which is the opposite of charity. It arouses in them a consciousness of their responsibilities. And finally, it confers upon parents a deeper and more effective influence in the edu
cation of their children. As their children grow up, they develop a right sense of values and achieve a serene and harmonious use of their mental and physical powers.

  Promotion of Chastity

  22. 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 (25) or by pleading the liberty which may be allowed in this field by the public authorities.

  Appeal to Public Authorities

  23. And now We wish to speak to rulers of nations. To you most of all is committed the responsibility of safeguarding the common good. You can contribute so much to the preservation of morals. We beg of you, never allow the morals of your peoples to be undermined. The family is the primary unit in the state; do not tolerate any legislation which would introduce into the family those practices which are opposed to the natural law of God. For there are other ways by which a government can and should solve the population problem—that is to say by enacting laws which will assist families and by educating the people wisely so that the moral law and the freedom of the citizens are both safeguarded.

  Seeking True Solutions

  We are fully aware of the difficulties confronting the public authorities in this matter, especially in the developing countries. In fact, We had in mind the justifiable anxieties which weigh upon them when We published Our encyclical letter . But now We join Our voice to that of Our predecessor John XXIII of venerable memory, and We make Our own his words: "No statement of the problem and no solution to it is acceptable which does violence to man's essential dignity; those who propose such solutions base them on an utterly materialistic conception of man himself and his life. The only possible solution to this question is one which envisages the social and economic progress both of individuals and of the whole of human society, and which respects and promotes true human values." (26) No one can, without being grossly unfair, make divine Providence responsible for what clearly seems to be the result of misguided governmental policies, of an insufficient sense of social justice, of a selfish accumulation of material goods, and finally of a culpable failure to undertake those initiatives and responsibilities which would raise the standard of living of peoples and their children. (27) If only all governments which were able would do what some are already doing so nobly, and bestir themselves to renew their efforts and their undertakings! There must be no relaxation in the programs of mutual aid between all the branches of the great human family. Here We believe an almost limitless field lies open for the activities of the great international institutions.

  To Scientists

  24. Our next appeal is to men of science. These can "considerably advance the welfare of marriage and the family and also peace of conscience, if by pooling their efforts they strive to elucidate more thoroughly the conditions favorable to a proper regulation of births." (28) It is supremely desirable, and this was also the mind of Pius XII, that medical science should by the study of natural rhythms succeed in determining a sufficiently secure basis for the chaste limitation of offspring. (29) In this way scientists, especially those who are Catholics, will by their research establish the truth of the Church's claim that "there can be no contradiction between two divine laws—that which governs the transmitting of life and that which governs the fostering of married love." (30)

  To Christian Couples

  25. And now We turn in a special way to Our own sons and daughters, to those most of all whom God calls to serve Him in the state of marriage. While the Church does indeed hand on to her children the inviolable conditions laid down by God's law, she is also the herald of salvation and through the sacraments she flings wide open the channels of grace through which man is made a new creature responding in charity and true freedom to the design of his Creator and Savior, experiencing too the sweetness of the yoke of Christ. (31)

  In humble obedience then to her voice, let Christian husbands and wives be mindful of their vocation to the Christian life, a vocation which, deriving from their Baptism, has been confirmed anew and made more explicit by the Sacrament of Matrimony. For by this sacrament they are strengthened and, one might almost say, consecrated to the faithful fulfillment of their duties. Thus will they realize to the full their calling and bear witness as becomes them, to Christ before the world. (32) For the Lord has entrusted to them the task of making visible to men and women the holiness and joy of the law which united inseparably their love for one another and the cooperation they give to God's love, God who is the Author of human life.

  We have no wish at all to pass over in silence the difficulties, at times very great, which beset the lives of Christian married couples. For them, as indeed for every one of us, "the gate is narrow and the way is hard, that leads to life." (33) Nevertheless it is precisely the hope of that life which, like a brightly burning torch, lights up their journey, as, strong in spirit, they strive to live "sober, upright and godly lives in this world," (34) knowing for sure that "the form of this world is passing away." (35)

  Recourse to God

  For this reason husbands and wives should take up the burden appointed to them, willingly, in the strength of faith and of that hope which "does not disappoint us, because God's love has been poured into our hearts through the Holy Spirit who has been given to us ~}36 Then let them implore the help of God with unremitting prayer and, most of all, let them draw grace and charity from that unfailing fount which is the Eucharist. If, however, sin still exercises its hold over them, they are not to lose heart. Rather must they, humble and persevering, have recourse to the mercy of God, abundantly bestowed in the Sacrament of Penance. In this way, for sure, they will be able to reach that perfection of married life which the Apostle sets out in these words: "Husbands, love your wives, as Christ loved the Church. . . Even so husbands should love their wives as their own bodies. He who loves his wife loves himself. For no man ever hates his own flesh, but nourishes and cherishes it, as Christ does the Church. . . This is a great mystery, and I mean in reference to Christ and the Church; however, let each one of you love his wife as himself, and let the wife see that she respects her husband." (37)

  Family Apostolate

  26. Among the fruits that ripen if the law of God be resolutely obeyed, the most precious is certainly this, that married couples themselves will often desire to communicate their own experience to others. Thus it comes about that in the fullness of the lay vocation will be included a novel and outstanding form of the apostolate by which, like ministering to like, married couples themselves by the leadership they offer will become apostles to other married couples. And surely among all the forms of the Christian apostolate it is hard to think of one more opportune for the present time. (38)

  To Doctors and Nurses

  27. Likewise we hold in the highest esteem those doctors and members of the nursing profession who, in the exercise of their calling, endeavor to fulfill the demands of their Christian vocation before any merely human interest. Let them therefore continue constant in their resolution always to support those lines of action which accord with faith and with right reason. And let them strive to win agreement and support for these policies among their professional colleagues. Moreover, they should regard it as an essential part of their skill to make themselves fully proficient in this difficult field of medical knowledge. For then, when married couples ask for their advic
e, they may be in a position to give them right counsel and to point them in the proper direction. Married couples have a right to expect this much from them.

  To Priests

  28. And now, beloved sons, you who are priests, you who in virtue of your sacred office act as counselors and spiritual leaders both of individual men and women and of families—We turn to you filled with great confidence. For it is your principal duty—We are speaking especially to you who teach moral theology—to spell out clearly and completely the Church's teaching on marriage. In the performance of your ministry you must be the first to give an example of that sincere obedience, inward as well as outward, which is due to the magisterium of the Church. For, as you know, the pastors of the Church enjoy a special light of the Holy Spirit in teaching the truth. (39) And this, rather than the arguments they put forward, is why you are bound to such obedience. Nor will it escape you that if men's peace of soul and the unity of the Christian people are to be preserved, then it is of the utmost importance that in moral as well as in dogmatic theology all should obey the magisterium of the Church and should speak as with one voice. Therefore We make Our own the anxious words of the great Apostle Paul and with all Our heart We renew Our appeal to you: "I appeal to you, brethren, by the name of our Lord Jesus Christ, that all of you agree and that there be no dissensions among you, but that you be united in the same mind and the same judgment." (40)
