The very rare cases when a pregnancy poses a genuine and immediate threat to the mother’s life are a source of great confusion, especially among Catholics.
It is absolutely true that the Catholic Church bans direct abortion in all cases. However, the mother’s life may be saved by surgery that does not directly attack the preborn baby’s life, even if the child may die as an indirect result of the procedure. This ethical principle is known as the principle of double effect.
The most common problems of this type are ectopic pregnancy, carcinoma of the uterine cervix, and cancer of the ovary. Occasionally, cancer of the vulva or vagina may require surgical intervention.1
In such cases, under the “principle of double effect,” physicians must do everything in their power to save both the mother and the child. In the case of an ectopic pregnancy, if the doctors decide that the mother’s life can only be saved by removing the Fallopian tube, and with it the preborn baby, or by removal of some other tissue essential for the preborn baby’s life, the baby will most likely die. But this kind of surgery would not be categorized as an abortion. This is the critical and fundamental difference between deliberate killing (abortion) and unintentional death. The intent is not to kill the preborn child, but to save the life of the mother.
Conditions of the Principle of Double Effect
The principle of double effect states that it is morally permissible to perform an action that will produce both good and bad effects as long as the following conditions are all met. The example shown below is for the treatment of an ectopic pregnancy, where the preborn child is developing in the Fallopian tube. If the child continues to grow there, the tube will eventually rupture and will probably cause the death of both the mother and the child.2
- The goal of the surgery itself must be good or at least morally neutral. In this case, the goal of the surgery is to remove a pathological organ which presents an imminent threat to the life of the woman—a good goal. By contrast, the goal of surgical or chemical abortion is simply to kill the preborn child.
- The good effect must not come about as a result of the evil effect, but must come directly from the good action, which in this case is the surgery intended to heal. The good effect (saving the mother’s life) is not caused by the bad effect (the death of the preborn child). By contrast, in the case of direct abortion (surgical or chemical abortion), the death of the child is wrongly considered to be the “good” effect.
- The evil effect must not be desired in itself but only permitted, if there is no other choice. In the case of the removal of an ectopic pregnancy, the surgeon does not intend or want to kill the baby; the baby’s death is an unintended and unwanted side effect of the surgery. By contrast, the intent of abortion is to kill the preborn child.
- There must be a sufficiently grave reason for permitting the evil effect to occur. In this case, the reason is to save the life of the mother when all other options for saving her life have been exhausted, a good that is greater than or equal to the evil effect of the baby’s death. Pro-abortion groups often stretch this principle to absurd lengths, going so far as to justify all abortions under the principle of double effect because, as they falsely allege, most or all pregnancies threaten the life of the mother.
The principle of double effect also applies to sexual sterilization. If a non-pregnant woman must have a hysterectomy to remove a dangerously cancerous uterus, this will result in her sterilization, but is not a sinful act (provided the above conditions are met). However, if the purpose of the operation is not to heal or safeguard health, but to directly sterilize, then that act is always mortally sinful.3
Misuse of the Principle of Double Effect
Sometimes the term “therapeutic” is used to describe certain cases of abortion. No direct abortion is therapy, since it never cures anyone of an illness, but instead kills an innocent human being. “Therapeutic” abortions are allegedly performed with the intention of saving the mother’s life, but where one or more of the four conditions of the principle of double effect are not met.
Basically, the doctor in this case does have alternatives which can save the both mother and her preborn child, but chooses abortion as the most expedient (or inexpensive) way to solve the problem at hand. It is a sign of the times that many pro-abortionists have stated that pregnancy itself as a disease, and present abortion as the “cure” for this dreaded malady.4
If we ever arrive at the point where the lives of both mother and child can be saved in all cases, the principle of double effect would be moot.5
Pope Pius XII summarized the intent of the principle of double effect in 1951: “Both for the one and the other, the demand cannot be but this: To use every means to save the life of both the mother and the child.”6
The Declaration on Procured Abortion reiterates the intent of the principle of double effect:
Deliberately we have always used the expression `direct attempt on the life of an innocent person,’ `direct killing.’ Because if, for example, the saving of the life of the future mother, independently of her pregnant condition, should urgently require a surgical act or other therapeutic treatment which would have as an accessory consequence, in no way desired or intended, but inevitable, the death of the fetus, such an act could no longer be called a direct attempt on an innocent life. Under these conditions the operation can be lawful, like other similar medical interventions ― granted always that a good of high worth is concerned, such as life, and that it is not possible to postpone the operation until after the birth of the child, nor to have recourse to other efficacious remedies [§14].
One of the most effective general tactics employed by pro-abortionists and other anti-lifers involves the assertion that “this is not a black and white question.” In other words, they would have us believe that there is some enormous (and of course undefined) grey area within which such ethical questions fall. This is the ultimate red herring. According to ‘Catholics’ for [a Free] Choice and other pro-abortionists, any abortion that any woman wants falls into this vast “gray area.”7
Canon law requires that the desired effect must be accomplished in such a way as to best assure the survival of both mother and child. Thus, the approved method of terminating a pregnancy is known as “birth,” usually occurring at about nine months’ gestation.

4. At an Association of Planned Parenthood Physicians conference, Willard Cates compared the miracle of pregnancy to a venereal disease when he said that “Unwanted pregnancy is transmitted sexually, is socially and emotionally pathologic … and has many other characteristics of the conventional venereal diseases. The incubation time, defined as the period between exposure (mid‑cycle coitus) and the development of initial symptoms (usually missed menses), averages approximately two weeks” [Willard Cates Jr., M.D., al. “Abortion as a Treatment for Unwanted Pregnancy: The Number Two Sexually‑Transmitted Condition.” Address presented to the Association of Planned Parenthood Physicians Conference, Miami Beach, Florida, November 11‑12, 1976]. Barbara Roberts said that “It’s obvious, therefore, that unwanted pregnancy is the most common venereal disease … This disease is associated with immense suffering. Seeking to be cured of this disease, women from time have risked pain, mutilation, and death in numbers that really stagger the imagination” [Barbara H. Roberts, M.D. “Abortion Laws Murder Women.” Essay in a Women’s National Abortion Action Coalition booklet entitled “Abortion is a Woman’s Right: March on Washington, DC and San Francisco, November 20 ”]. Finally, late‑term abortionist Warren Hern has said:
[Pregnancy] is an episodic, moderately extended, chronic condition … defined as an illness … treated by evacuation of the uterine contents. … The relationship between the gravid female and the feto‑placental unit can be understood best as one of host and parasite. Pregnancy should be seen as a biocultural event in the context of other human illnesses” [Warren Hern. “Is Pregnancy Really Normal?” Alan Guttmacher Institute’s Family Planning Perspectives, January 1971, page 9; Warren Hern. Abortion Practice [Philadelphia: J.B. Lippincott Company], 1984].
5. In some countries there currently exist advanced techniques that can save both the mother and her preborn child even in the extreme case of a tubal pregnancy. Abdominal pregnancies present a less difficult scenario insofar as saving both mother and child, because less advanced technology is required than in the case of tubal pregnancies.
In the case where the particular medical facility does not have such technology available to save tubal babies, competent moralists and doctors affirm that with the present medical technology we can diagnose such pregnancies earlier than before, and we can also accompany expectantly (ready to act but without intervening) a woman pregnant with a tubal preborn baby until we can attempt to save him (if that is indeed possible) or until we know the tubal baby has unfortunately died, in order to then remove him or her without damage to the mother. This way of acting is more respectful towards the preborn baby and the one to be followed, and we should set aside utilitarian considerations about costs, etc. [Niceto Blázquez. Bioética Fundamental. Madrid: Biblioteca de Autores Cristianos, 1996].
Of course, where none of the above techniques are available, the doctors will do the best they can to save both mother and child or at least one of them under the principle of double effect.
We must also clarify that many times doctors, when faced with what they think is a tubal pregnancy, immediately rush to intervene without the proper diagnosis. And when they do intervene, they use drugs or other means to kill the tubal baby and then remove him or her. This is gravely immoral and does not constitute a correct use of the principle of double effect but a direct abortion.
Every effort should be made to obtain those techniques to save mother and preborn child and also to prevent ectopic pregnancies, since not enough is being done in this area.
Let us keep in mind that many ectopic pregnancies are caused by promiscuity, which can result in sexually transmitted diseases (STDs) and/or the use of the intrauterine device (IUD), which is also abortifacient.
The case of the cancerous uterus in a pregnant woman no longer presents a problem in saving both mother and preborn child. Therefore the principle of double effect cannot be invoked any longer in this case to justify an intervention that results in the death of the preborn baby [Blázquez, op. cit.].
6. Pope Pius XII, address to the Family Front Congress on November 27, 1951, published in Matrimony, Papal Teachings [Boston: Paul Editions], 1963, pages 437 to 440. The complete passage is below:
It has been our intention here to use always the expressions “direct attempt on the life of the innocent person” [and] “direct killing.” The reason is that if, for example, the safety of the life of the future mother, independently of her state of pregnancy, might call for an urgent surgical operation, or any other therapeutic application, which would have as an accessory consequence, in no way desired nor intended, but inevitable, the death of the fetus, such an act could not be called a direct attempt on the innocent life. In these conditions the operation can be lawful, as can other similar medical interventions, provided that it be a matter of great importance, such as life, and that it is not possible to postpone it till the birth of the child, or to have recourse to any other efficacious remedy …. Both for the one and the other, the demand cannot be but this: To use every means to save the life of both the mother and the child.
Pius also stated the general principle of double effect on October 29, 1951, at his address to the Italian Union of Midwives. This speech is codified in the Pope’s Acta Apostilicae Sedis, 43(1951), page 855.
7. Frances Kissling, former President of ‘Catholics’ for [a Free] Choice (CFFC), shows us how far pro‑abortionists will contort themselves in order to justify abortion on demand:
For example, the just war theory accepts the taking of human life if one’s own life or that of another is directly threatened. A just abortion theory would therefore permit a woman whose life was in danger to have an abortion ― an act now prohibited by church law. Just war theory has also accepted that war can be warranted to protect a nation’s integrity, particularly if the violation of a nation would result in the erosion of values judged to be equal to or greater than life itself. This could include territorial violation that would result in loss of liberty or traditional freedoms such as religion and speech. Could not a just abortion theory admit that threats to a woman’s physical and emotional health are a violation of bodily integrity comparable to national integrity? Could not a woman’s capacity to care for existing children and children to come, her ability to function as a fully contributing member of our society and her sense of self identity and purpose be seen as values proportional to the potential value of fetal life?
