Address of His Holiness Pius XII to the VII congress of the International Society of Hematology 1AAS 50 (1958) 732-740.
Friday, September 12, 1958
The VII International Congress of Hematology, which brings together more than a thousand specialists from different countries in Rome, has suggested to you, Gentlemen, the thought of paying us a visit. We are very grateful for that and we welcome you warmly. Your assembly was preceded by the International Congress for the Transfusion of Blood, which we also had the pleasure of addressing.
A simple look at the topics listed in your program is enough to show the variety and abundance of the problems that arise today in hematology. We find in it, among the topics discussed in the plenary sessions, issues concerning immunohematology, hemorrhagic disorders, leukemia, spleen and the reticuloendothelial system, anemia, the use of radioactive isotopes in hematology. To these matters are added the lectures and discussions that are the subject of the colloquiums. Thus you have the possibility to enrich your scientific knowledge and to apply it better to daily life, to individuals and families, to whom these progresses are finally destined. It can be said that the problems of blood, inherited from previous generations.
The work already cited in Our previous Address in relation to genetic consultation ( Sheldon C. Reed, Counseling in Medical Genetics ) exposes the different ways in which the solution of the problem of defective inheritance is currently presented.
According to this work, since the technique of artificial fertilization has been discovered, semiadoption has been used to a great extent to have children, when the husband is sterile or when the couple has discovered that they were carriers of a serious recessive gene. If the adoptive father has doubts about the legality of the child that his wife has fathered by this method, it can be remedied simply by adoption. A scientific report published in 1954 indicates that couples, who suspect each other of their sterility, tend to want to determine which of them is the cause of it, resorting to voluntary adultery. To prevent tragic experiences of this kind, a fertility clinic can be very useful.
Another very typical case is that of the woman who goes to the genetic consultation, because she knows that she has a hereditary disease; and, not being able to accept the contraceptive means, he intends to undergo sterilization.
The first case mentioned as a solution to the problem of husband sterility artificial insemination, which is obviously a “donor” stranger to the couple. We already had occasion to take a position against this practice in the address addressed to the IV International Congress of Catholic Doctors on September 29, 1949 . We absolutely fail the insemination between unmarried people and even between spouses. We returned to this question in Our Address to the World Fertility Congress on May 19, 1956, to reprove again all species of artificial insemination, since this practice is not included among the rights of the spouses and is contrary to the natural law and Catholic morality. As for the artificial insemination between celibates, as early as 1949 we declared that it violates the principle of natural right, that all new life can not be procreated except in a valid marriage.
The solution for voluntary adultery condemns itself, whatever the biological, eugenic and juridical reasons for which it is tried to justify. No husband can make his conjugal rights available to a third person, and any attempt to renounce them is without effect; nor to rely on the legal axiom: ” volenti non fit iniuria “.
It is also considered as a solution the sterilization, either of the person, or of the act itself. Due to biological and eugenic reasons, these two methods are currently receiving a growing favor and are progressively disseminated under the protection of new drugs that are increasingly effective and more comfortable to use. The reaction of certain groups of theologians to this state of affairs is symptomatic and very alarming. It reveals a deviation from moral judgment, which goes hand in hand with an exaggerated readiness to review, in favor of new techniques, commonly received positions. This attitude comes from a praiseworthy intention that, to help those in difficulty, refuses to exclude new possibilities of solution too soon. But this adaptation effort is applied here in an unfortunate way, since some principles are misunderstood or given a meaning or transcendence that they can not have. The Holy See is then in a situation similar to that of Blessed Innocent XI, who was more than once forced to condemn moral theses proposed by theologians animated by an indiscreet zeal and a little clairvoyant daring 2Cf. Denzinger , n. 1151-1261, 1221-1288..
Many times we have already dealt with sterilization. In substance, we have stated that direct sterilization was not authorized by the right of man to dispose of his own body, and can not, therefore, be considered as a valid solution to prevent the transmission of a sick inheritance. “Direct sterilization, we said on October 29, 1951, that is, the one that attempts, as a means or as an end, to make procreation impossible, is a serious violation of the moral law and, consequently, is unlawful. Neither the same public authority has the right, under the pretext of any indication, to allow, much less to prescribe it or to have it executed against innocents. This principle is already enunciated in the encyclical Casti connubii , of Pío XI, on the marriage. Also, when, a dozen years ago, sterilization began to be increasingly applied, the Holy See felt the need to expressly and publicly declare that the direct, perpetual or temporary sterilization of both men and women, it is unlawful by virtue of the natural law, in which neither the Church itself, as you know, can dispense ». 3Address to the Italian Catholic Union of Obstetricians and to the National Federation of Catholic Midwives’ Colleges , October 29, 1951, AAS 43 (1951) 835 ff.
By direct sterilization we wanted to designate the action of the one who proposes as an end or as a means, to make procreation impossible; but we do not apply this term to any action that makes procreation in fact impossible. Man, in fact, does not always intend to do what results from his actions, although he has foreseen it. Thus, for example, the removal of diseased ovaries will have the necessary consequence of making procreation impossible; but this impossibility may not have been wanted, neither as an end nor as a means. We repeat in detail the same explanations in Our address of October 8, 1953 to the Congress of Urologists 4Cf. AAS 45 (1953) 673 ss .; Discorsi e Radiomessaggi , vol. XV, p. 373-379. The same principles apply to the present case and prohibit considering the removal of sexual glands and organs as lawful, in order to prevent the transmission of defective hereditary characters.
These same principles also allow us to resolve a question that is much discussed today between doctors and moralists. Is it permissible to prevent ovulation by means of pills used as remedies in the exaggerated reactions of the uterus and the organism, although these drugs, by preventing ovulation, also make fertilization impossible? Is it permissible to use a married woman who, despite this temporary sterility, wishes to have sex with her husband? The answer depends on the intention of the person. If the woman takes this medication, not with the intention of preventing conception, but only by medical indication, as a necessary remedy because of a disease of the uterus or organism, it causes indirect sterilization, which is allowed according to the general principle of the double-effect actions. But direct sterilization is provoked and, therefore, illicit, when ovulation is prevented in order to preserve the uterus and the organism from the consequences of a pregnancy that it is not capable of supporting. Certain moralists claim that it is permissible to take medication for this purpose, but it is a wrong opinion. It is also necessary to reject the opinion of many doctors and moralists who allow its use, when a medical indication makes a very similar conception undesirable, or in other similar cases, which can not be mentioned here. In these cases, the use of medications is intended to prevent conception, preventing ovulation; then it’s about direct sterilization. When ovulation is prevented in order to preserve the uterus and the organism from the consequences of a pregnancy it is not able to withstand.
To justify it, a principle of moral right in itself is often cited, but misinterpreted: “licet corrigere defectus naturae ,” it is said, and since in practice it is sufficient to use this principle to have a reasonable probability, it is intended that this is a matter of correcting a natural defect. If this principle had an absolute value, eugenics could without hesitation use the method of drugs to prevent the transmission of a defective inheritance. But it is still necessary to see how the natural defect is corrected and to take good care not to violate other principles of morality in any way.
It is also proposed, as a means capable of preventing the transmission of a defective inheritance, the use of condoms and the Ogino-Knaus method. -The eugenics specialists, who absolutely condemn its use when it is simply a question of giving impulse to passion, approve these two systems when there are serious hygienic indications; they consider them a lesser evil than the procreation of moronic children. Although some approve of this position, Christianity has always followed and continues to follow a different tradition. Our predecessor, Pius XI, put it in a solemn way in his encyclical Casti connubii , of December 31, 1930. He qualifies the use of condoms as a violation of natural law; an act, to which nature has given the power to arouse a new life, is deprived of it by the human will: “quemlibet matrimonii usum ,” he wrote, “in quo exercendo, actus of industry hominum, naturali sua vitae procreandae vi destitituatur, Dei et naturae legem infringere, et eos qui tale quid commiserint gravis noxae labe commaculari ».
On the contrary, the use of natural temporal sterility, according to the doctor Ogino-Knaus, does not violate the natural order, as the practice described above, since conjugal relations respond to the will of the Creator. When this method is used for serious reasons (and the indications of eugenic type can have a serious character), it is morally justified. We already spoke in Our address of October 29, 1951, not to expose the biological or medical point of view, but to put an end to the conscience concerns of many Christians who used it in their conjugal life. On the other hand, in his Encyclical of December 31, 1930, Pius XI had already formulated the position of principle: “Neque c ontra naturae ordinem agere ii dicendi sunt coniuges, qui iure suo recte et naturali ratione utuntur, etsi ob naturalis sive temporis sive quorundam defectuum causes nova inde vita oriri non possit ».
We need in our 1951 address that husbands, who make use of their matrimonial rights, have a positive obligation, by virtue of the natural law of their state, not to exclude procreation. The Creator, in fact, wanted the human race to spread precisely through the natural exercise of the sexual function. But to this positive law we applied the principle that applies to all other laws: they do not bind to the extent that their fulfillment brings with it notable drawbacks, which are not inseparable from the law itself, nor inherent to its fulfillment, but come from another part, and that the legislator has not had the intention to impose on men when it has promulgated the law.
The last means mentioned above, and on which we want to express our opinion, was that of adoption. When it is necessary to discourage natural procreation, because of the danger of a tared inheritance, spouses who would like to at least have a child, are suggested the system of adoption. And it also states that this advice is, in general, followed by happy results, and gives parents happiness, peace, serenity. From the religious and moral point of view, the adoption does not raise any objection; it is an institution recognized in almost all civilized states. If certain laws contain unacceptable moral provisions, this does not happen with the institution of adoption, as such. From the religious point of view, it is necessary to ask that the children of Catholics be taken, in adoption, by adoptive Catholic parents.
