Procured abortion The Catholic Church teaches that procured abortion is a mortal sin against the Fifth Commandment ("
Thou shalt not kill"). The church teaches that procured abortion is an intrinsic evil and a crime against human life, dignity, and freedom because it is the murder (direct intentional killing) of a human being (unborn person). The church also teaches that procured abortion cannot be justified, legalized, participated or cooperated in, or procured -- partially or fully -- by any means, for any reason, or under any circumstance. The church further teaches that there is no right to procured abortion. Under the
1983 Code of Canon Law, the law advocates for "crimes against human life, dignity, and freedom." Can. 1398 states that procured abortion incurs a
latae sententiae (
excommunication).
Unintentional abortion The principle of double effect is frequently cited in relation to abortion. A doctor who believes abortion is always morally wrong may nevertheless remove the uterus or fallopian tubes of a pregnant woman, knowing the procedure will cause the death of the embryo or fetus, in cases in which the woman is certain to die without the procedure (examples cited include aggressive
uterine cancer and
ectopic pregnancy). In these cases, the intended effect is to save the woman's life, not to terminate the pregnancy, and the death of the embryo or fetus is a side effect. The death of the fetus is an undesirable but unavoidable consequence.
Ectopic pregnancy An
ectopic pregnancy is one of a few cases where the foreseeable death of an embryo is allowed, since it is categorized as an
indirect abortion. This view was also advocated by Pius XII in a 1953 address to the Italian Association of Urology. Using the Thomistic Principle of Totality (removal of a pathological part to preserve the life of the person) and the Doctrine of Double Effect, the only moral action in an ectopic pregnancy where a woman's life is directly threatened is the removal of the tube containing the human embryo (
salpingectomy). The death of the human embryo is unintended although foreseen. The use of
methotrexate and salpingostomy remains controversial in the Catholic medical community, and the Church has not taken an official stance on these interventions. The Catholic Health Association of the United States, which issues guidelines for Catholic hospitals and health systems there, allows both procedures to be used. The argument that these methods amount to an indirect abortion revolves around the idea that the removal of the Fallopian tube or, in the case of methotrexate, the chemical destruction of the trophoblastic cells (those which go on to form the placenta), does not constitute a direct act upon the developing embryo. Individual hospitals and physicians, however, may choose to prohibit these procedures if they personally interpret these acts as a direct abortion. Despite the lack of an official pronouncement by the Church on these treatments, in a 2012 survey of 1,800 Ob/Gyns who work in religious hospitals, only 2.9% of respondents reported feeling constrained in their treatment options by their employers, suggesting that in practice, physicians and healthcare institutions generally choose to treat ectopic pregnancies.
Embryos The Church considers the destruction of any embryo to be equivalent to abortion, and thus opposes
embryonic stem cell research. According to the Seven Themes of Catholic Church Justice, the first theme is the life and dignity of the Human Person. The Church emphasizes that every person, from the moment of conception, is deemed unique in the eyes of God and has a right to innate dignity. Therefore, no human or human quality can revoke an individual's rights. Due to this,
abortifacients such as emergency contraception (EC), IVFs (In Vitro Fertilization), and hormonal contraception are deemed a form of abortion because they deny an embryo the right to life. Furthermore, embryonic stem cell research is highly opposed in the Catholic faith. The action of utilizing embryonic stem cells to conduct experiments on and refute their right to live is a direct opposition to the Catholic Church. It is seen as "dehumanizing" in the eyes of Catholicism, and using any human person without their consent as "body parts" is against their moral responsibility. IVF is a strong example of this belief. Parents or surrogates who receive IVF face many challenges, such as an unwanted embryo due to genetic imperfections, undesired sex traits, or unintentional death due to the storage of IVF treatment. These actions deny the embryo the unique experience of living and the innate dignity through their development. The
Catholic Social Teaching furthers this moral obligation in the understanding of God's gift of human life and the worthiness of respect to be a part of the human family.
Sanctions Catholics who procure a completed abortion are subject to a
latae sententiae excommunication. That means that the excommunication is not imposed by an authority or trial (as with a
ferendae sententiae penalty); rather, being expressly established by
canon law, it is incurred
ipso facto when the delict is committed (a
latae sententiae penalty). Canon law states that in certain circumstances "the accused is not bound by a
latae sententiae penalty"; among the ten circumstances listed are commission of a delict by someone not yet sixteen years old, or by someone who without
negligence does not know of the existence of the penalty, or by someone "who was coerced by grave fear, even if only relatively grave, or due to necessity or grave inconvenience". According to a 2004 memorandum by
Joseph Cardinal Ratzinger, Catholic politicians who consistently campaign and vote for permissive abortion laws should be informed by their
priest of the Church's teaching and warned to refrain from receiving the
Eucharist or risk being denied it until they end such activity. This position is based on
Canon 915 of the
1983 Code of Canon Law and has also been supported, in a personal capacity, by Archbishop
Raymond Leo Cardinal Burke, the former
Prefect of the
Apostolic Signatura.
Pope Francis reaffirmed this position in March 2013, when he stated that "[people] cannot receive Holy Communion and at the same time act with deeds or words against the commandments, particularly when abortion, euthanasia, and other grave crimes against life and family are encouraged. This responsibility weighs particularly over legislators, heads of governments, and health professionals".
Forgiveness of women who abort Apart from indicating in its
canon law that automatic excommunication does not apply to women who abort because of grave fear or due to grave inconvenience, the Catholic Church, without making any such distinctions, assures the possibility of forgiveness for women who have had an abortion.
Pope John Paul II wrote: On the occasion of the
Extraordinary Jubilee of Mercy in 2015,
Pope Francis announced that all priests (during the Jubilee yearending November 20, 2016) will be allowed in the
Sacrament of Penance to refrain from enforcing the penalty of excommunication for
abortion, which had been reserved to bishops and certain priests who were given such mandate by their bishop. This policy was made permanent by an
apostolic letter titled
Misericordia et misera (Mercy and Misery), which was issued on November 21, 2016.
Recent statements of the Church's position The Church teaches that "human life must be respected and protected absolutely from the moment of conception. From the first moment of his existence, a human being must be recognized as having the rights of a person – among which is the inviolable right of every innocent being to life". the
Catholic Catechism teaches that the embryo must be treated from conception "as" (Latin:
, "as if") a human person. The
New Catholic Encyclopedia concludes:
Tadeusz Pacholczyk of the
National Catholic Bioethics Center writes that the modern Magisterium has carefully avoided confusing "human being" with "human person", and avoids the conclusion that every embryonic human being is a person, which would raise the question of "
ensoulment" and immortal destiny. The
Catechism of the Catholic Church says that since the 1st century the Church has affirmed that every procured abortion is a moral evil; the
Catechism states that this position "has not changed and remains unchangeable". The Church teaches that the inalienable
right to life of every innocent human being is a constitutive element of a civil society and its legislation. In other words, it is beholden upon society to legally protect the life of the unborn. Catholic theologians trace Catholic thought on abortion to early Christian teachings such as the
Didache, the
Epistle of Barnabas and the
Apocalypse of Peter. In contrast, Catholic philosophers
Daniel Dombrowski and Robert Deltete analyzed Church theological history and the "development of science" in
A Brief, Liberal, Catholic Defense of Abortion to argue that a position in favor of abortion rights is "defensibly Catholic".
COVID-19 vaccines Due to the anti-abortion stance, some Catholics oppose receiving vaccines derived from fetal cells obtained via abortion. On 21 December 2020, and regarding
COVID-19 vaccination, the
Congregation for the Doctrine of the Faith emitted a document stating that "it is morally acceptable to receive COVID-19 vaccines that have used cell lines from aborted fetuses in their research and production process" when no alternative vaccine is available, since "the moral duty to avoid such passive material cooperation is not obligatory if there is a grave danger, such as the otherwise uncontainable spread of a serious pathological agent." The document states that receiving the vaccine does not constitute endorsement of the practice of abortion, and that "the morality of vaccination depends not only on the duty to protect one's own health, but also on the duty to pursue the common good." The document cautions further: ==Attitudes of Catholic laity==
