Few questions divide families, churches and nations like this one. Is abortion a sin? Many Christians are sure the answer is yes, but could not show it from the Bible if a friend asked. Many others have heard that the Bible never mentions abortion, so it must be a private matter between a woman, her doctor and her conscience.
Behind every argument are real people: a frightened young woman, a pressured couple, a father who was never asked, a doctor, a grandmother who drove her daughter to the clinic. And a child who has no voice at all.
Here is the precise answer, from Scripture, from the first Christians, from the Catholic Church and from reason. And here, just as clearly, is the way back for anyone who has been part of an abortion.
Short answer: Yes. Direct abortion, the deliberate ending of an unborn child's life, whether as a goal or as a means to something else, is a grave sin, because it is the intentional killing of an innocent human being. Scripture forbids shedding innocent blood and speaks of the child in the womb as someone God already knows and forms. Christians have condemned abortion since the first century, and the Catholic Church teaches that this "has not changed and remains unchangeable" (CCC 2271). But abortion is not unforgivable: "there is no sin that God's mercy cannot reach and wipe away when it finds a repentant heart" (Misericordia et Misera 12).

What Defenders of Abortion Argue
The case for abortion is not one argument but several, and each deserves to be heard at its strongest.
1. "It isn't a person yet." Many people grant that an embryo is human tissue but deny that it is a person. On this view personhood begins later: at viability, when the brain can support consciousness, when the fetus can feel pain, or at birth. Early abortion, then, ends a potential life, not an actual one.
2. "My body, my choice." Others grant, for the sake of argument, that the unborn child is a person, and defend abortion anyway: no one may be forced to use her body to keep another person alive. A famous philosophical thought experiment compares pregnancy to waking up attached to a stranger who needs your kidneys for nine months. Staying attached would be generous, the argument says, but justice cannot demand it.
3. "The hard cases." Pregnancy after rape. A threat to the mother's life. A diagnosis of severe disability. Crushing poverty. In such cases, it is argued, forbidding abortion is cruel.
4. "The Bible is silent, or even permits it." Some Christians point out that Scripture never uses the word "abortion." They argue that Exodus 21:22 punishes causing a miscarriage with only a fine, that a human being becomes a "living being" only with the breath of life (Genesis 2:7), and that God Himself commanded a ritual in Numbers 5 that some read as ending a pregnancy. Some Protestant denominations hold that abortion can be a morally acceptable choice in certain circumstances.
Behind many of these arguments is a good and real concern: love for women in desperate situations. The Catholic Church shares that concern completely. The question is whether the answer to a woman's desperation can ever be the death of her child.
What Catholics Actually Teach
The foundation is the sacredness of every human life: "Human life is sacred because from its beginning it involves the creative action of God and it remains for ever in a special relationship with the Creator, who is its sole end." Therefore, "no one can under any circumstance claim for himself the right directly to destroy an innocent human being" (CCC 2258).
Applied to the unborn: "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" (CCC 2270). And: "Since the first century the Church has affirmed the moral evil of every procured abortion. This teaching has not changed and remains unchangeable. Direct abortion, that is to say, abortion willed either as an end or a means, is gravely contrary to the moral law" (CCC 2271). The Second Vatican Council taught that "from the moment of its conception life must be guarded with the greatest care while abortion and infanticide are unspeakable crimes" (Gaudium et Spes 51).
Pope St. John Paul II gave this teaching its most solemn form. Speaking "by the authority which Christ conferred upon Peter and his Successors, in communion with the Bishops," he declared "that direct abortion, that is, abortion willed as an end or as a means, always constitutes a grave moral disorder, since it is the deliberate killing of an innocent human being" (Evangelium Vitae 62).
Because so much is at stake, the Catholic Church attaches a penalty: "A person who actually procures an abortion incurs a latae sententiae excommunication" (canon 1397 §2), that is, one that takes effect by the act itself. Yet the Catechism adds that the Church "does not thereby intend to restrict the scope of mercy" (CCC 2272). Canon law itself spares from this automatic penalty anyone under sixteen, and those whose responsibility is lessened, such as a minor aged sixteen or seventeen or someone who acted under grave fear (canons 1323–1324). The act is always gravely wrong; the penalty is medicinal. It exists to call a person back to Christ in confession.
What about when a mother's life is in danger? The Catholic Church distinguishes killing from treating. The U.S. bishops' Ethical and Religious Directives state: "Operations, treatments, and medications that have as their direct purpose the cure of a proportionately serious pathological condition of a pregnant woman are permitted when they cannot be safely postponed until the unborn child is viable, even if they will result in the death of the unborn child" (Directive 47). What is never permitted is procured abortion, "the 'deliberate and direct killing, by whatever means it is carried out, of a human being in the initial phase of his or her existence, extending from conception to birth'" (Directive 45, quoting Evangelium Vitae 58).
What Catholics do not teach:
- That abortion is unforgivable. Pope Francis granted "to all priests, in virtue of their ministry, the faculty to absolve those who have committed the sin of procured abortion" (Misericordia et Misera 12).
- That a mother's life matters less than her child's. Both lives are sacred. Urgent treatment to save the mother is permitted even when the child's death is a foreseen but unintended result (Directive 47).
- That a miscarriage is a sin. A miscarriage is a death to be grieved, not a choice to be confessed.
- That the Church has defined the exact moment the soul is created. The Congregation for the Doctrine of the Faith "expressly leaves aside the question of the moment when the spiritual soul is infused," and explains why the answer to abortion does not depend on it (Declaration on Procured Abortion, note 19; see objection (g) below).
It all points to Christ. The eternal Son of God once lived in a womb: "it is through the holy Spirit that this child has been conceived in her" (Matthew 1:20). While He was still unborn, His unborn cousin, St. John the Baptist, leaped for joy at His presence, and St. Elizabeth called Mary "the mother of my Lord" (Luke 1:43). As the NABRE note says, "Even before his birth, Jesus is identified in Luke as the Lord." Every unborn child bears the image of the God who became an unborn child, and the blood Jesus shed on the Cross was shed for everyone who has ever shed innocent blood.
The Biblical Case
The word "abortion" does not appear in the Bible. Pope St. John Paul II said so himself: "The texts of Sacred Scripture never address the question of deliberate abortion and so do not directly and specifically condemn it" (Evangelium Vitae 61). But Scripture does not need to name every way of killing in order to forbid it. It teaches two truths, and the conclusion follows from them: God forbids the deliberate killing of innocent human beings, and the child in the womb is an innocent human being whom God knows by name.
1. God forbids shedding innocent blood
"You shall not kill" (Exodus 20:13). The reason runs back to creation: "Anyone who sheds the blood of a human being, by a human being shall that one's blood be shed; For in the image of God have human beings been made" (Genesis 9:6). The NABRE note explains that this image "is the basis of the dignity of every individual." Among the things the LORD hates are "hands that shed innocent blood" (Proverbs 6:17). No one is more innocent than a child who has not yet been born. As Pope St. John Paul II wrote of the unborn, "No one more absolutely innocent could be imagined" (Evangelium Vitae 58).
2. God knows and forms each child in the womb
Scripture never speaks of the unborn as tissue that later becomes a person. It speaks of a person God is already making. "You formed my inmost being; you knit me in my mother's womb." "Your eyes saw me unformed; in your book all are written down; my days were shaped, before one came to be" (Psalm 139:13, 16). Notice the word me: the psalmist does not say God knit some material that would one day become him. He says God knit him, even when he was "unformed."
God says to Jeremiah: "Before I formed you in the womb I knew you, before you were born I dedicated you" (Jeremiah 1:5). The servant of the Lord says: "Before birth the LORD called me, from my mother's womb he gave me my name" (Isaiah 49:1). Job grounds the equal dignity of master and servant in the womb itself: "Did not he who made me in the belly make him? Did not the same One fashion us in the womb?" (Job 31:15). And: "With skin and flesh you clothed me, with bones and sinews knit me together. Life and love you granted me" (Job 10:11–12).
3. Scripture calls the unborn and the newborn by the same name
When Mary greeted Elizabeth, "the infant leaped in her womb" (Luke 1:41), and Elizabeth said, "the infant in my womb leaped for joy" (Luke 1:44). The Greek word St. Luke uses for the unborn John is brephos. He uses the very same word for the newborn Jesus: "you will find an infant wrapped in swaddling clothes and lying in a manger" (Luke 2:12), and for the little children brought to Jesus: "People were bringing even infants to him" (Luke 18:15). Thayer's Greek lexicon lists both senses of the one word: "an unborn child, embryo, fetus" in Luke 1:41 and 44, and "a new-born child, an infant, a babe" in the others (Strong's 1025). To St. Luke, an unborn baby and a born baby are the same kind of being at different ages.
And John is no passive tissue. He "will be filled with the holy Spirit even from his mother's womb" (Luke 1:15), and he leaps "for joy." Joy belongs to a person.
4. Scripture counts a child from conception
The angel tells Mary that "Elizabeth, your relative, has also conceived a son in her old age" (Luke 1:36). Not a potential son: a son, already conceived. The angel tells St. Joseph that "this child has been conceived in her" (Matthew 1:20). David traces his own story back to his conception: "in sin my mother conceived me" (Psalm 51:7; KJV 51:5). (The NABRE note explains that the verse speaks of lifelong sinfulness and "does not imply that the sexual act of conception is sinful"; the point here is only that the "me" goes back to conception.)
Consider the Visitation once more. Right after the Annunciation, "Mary set out and traveled to the hill country in haste" (Luke 1:39). When she arrived, Jesus had been in her womb only a short time, and Elizabeth already greeted Him as "my Lord" (1:43). The Lord of glory was honored as Lord in the first weeks of His life in the womb.
Biology confirms what Scripture shows. At fertilization, sperm and egg unite "to form a zygote" (StatPearls, "Embryology, Fertilization"), and a standard developmental biology textbook titles its chapter on the subject "Fertilization: Beginning a new organism" (Gilbert, Developmental Biology, ch. 7). As the Catholic Church put it: "From the time that the ovum is fertilized, a life is begun which is neither that of the father nor of the mother, it is rather the life of a new human being with his own growth" (Declaration on Procured Abortion 12).
5. Children are a gift, and the womb is holy ground
"Certainly sons are a gift from the LORD, the fruit of the womb, a reward" (Psalm 127:3). When the angel announced Samson's birth, he told his mother to drink no wine or beer during her pregnancy, "for the boy is to be a nazirite for God from the womb" (Judges 13:5). God cared what the mother consumed because the child in her womb already belonged to Him.
The heroic mother of the seven Maccabean martyrs told her sons: "I do not know how you came to be in my womb; it was not I who gave you breath and life, nor was it I who arranged the elements you are made of" (2 Maccabees 7:22). A mother does not create her child. God does, and He gives "breath and life" in the womb. (On 2 Maccabees, see Why Do Catholic Bibles Have 7 More Books?)
6. God judges the killing of children
Scripture's harshest words fall on those who killed children. Israel's apostasy reached its depth when "They sacrificed to demons their own sons and daughters, Shedding innocent blood, the blood of their own sons and daughters" (Psalm 106:37–38). Pharaoh "oppressed [our] ancestors by forcing them to expose their infants, that they might not survive" (Acts 7:19); the word for "infants" there is again brephos. Herod "ordered the massacre of all the boys in Bethlehem and its vicinity two years old and under," and Rachel wept for her children "since they were no more" (Matthew 2:16–18). Scripture never treats the killing of the very young as a private matter.
7. God commands us to speak for those who cannot
"Did you fail to rescue those who were being dragged off to death… because you said, 'We didn't know about it'? Surely, the Searcher of hearts knows and will repay all according to their deeds" (Proverbs 24:11–12). "Open your mouth in behalf of the mute, and for the rights of the destitute" (Proverbs 31:8). God sets before every generation the same choice: "I have set before you life and death, the blessing and the curse. Choose life, then, that you and your descendants may live" (Deuteronomy 30:19). And Jesus says: "whoever receives one child such as this in my name receives me" (Matthew 18:5).
Objections Answered
(a) "The Bible never mentions abortion, so it's a matter of conscience."
At its strongest: No verse says, "You shall not have an abortion." Abortion was known in the ancient world; if it mattered so much, Scripture would have named it. Where the Bible is silent, Christians should leave the matter to each person's conscience.
Answer: Scripture never gives a specific law against poisoning a spouse or smothering a newborn, yet no Christian thinks those are matters of private conscience. God's law works by principle: "You shall not kill," applied to every innocent human being. The Bible's silence about the word is not silence about the act, because the Bible is anything but silent about the child in the womb (sections 2–4 above).
And we know how the first generations of Christians applied the commandment. The Didache, an early Christian manual of moral teaching commonly dated to the late first century, sets in the same list as the command against murder this one: "you shall not murder a child by abortion nor kill that which is begotten" (Didache 2). That is what Exodus 20:13 meant to the first Christians. Christ gave His Church authority to teach His law in every age (Matthew 16:19), and St. Paul calls the Church "the pillar and foundation of truth" (1 Timothy 3:15). On this question that Church has spoken with one voice "since the first century" (CCC 2271).
(b) "Exodus 21:22 punishes causing a miscarriage with only a fine."
At its strongest: The NABRE itself reads: "When men have a fight and hurt a pregnant woman, so that she suffers a miscarriage, but no further injury, the guilty one shall be fined as much as the woman's husband demands of him" (Exodus 21:22). If the woman is injured, "you shall give life for life" (21:23). So the Law of Moses treated the loss of the unborn child as a lesser matter than the loss of an adult life.
Answer: First, translators disagree about what this verse describes. The English Standard Version reads "her children come out," and the New International Version and New American Standard Bible read "gives birth prematurely" (Exodus 21:22, parallel translations). On that reading, the child is born alive, and "if injury ensues… life for life" protects the child as well as the mother. The NABRE's own note describes her as "a woman about to give birth."
Second, grant the miscarriage reading. The case is an accidental injury during a brawl, not a deliberate killing. The Law always distinguished accidental from intentional killing, even of adults (see the cities of refuge in Numbers 35). A penalty for accidentally causing a child's death tells us nothing that permits deliberately causing it. If anything, it shows that God's law protected the unborn even from accidents. Third, no verse anywhere in Scripture permits anyone to intend the death of an unborn child.
(c) "Life begins with the first breath (Genesis 2:7)."
At its strongest: "The LORD God formed the man out of the dust of the ground and blew into his nostrils the breath of life, and the man became a living being" (Genesis 2:7). A human being becomes a "living being" with the first breath, at birth.
Answer: Genesis 2:7 describes the creation of the first man from dust, not how his descendants come to be. Adam had no mother; every other human being comes from living parents and is alive from the start. Scripture shows children alive and active before they ever breathe air: John "leaped for joy" in the womb (Luke 1:44). The mother of the Maccabees says God gave her sons "breath and life" in the womb (2 Maccabees 7:22). Job says God granted him "life and love" as He knit him together (Job 10:11–12). Read the breath of Genesis 2:7 as the moment of birth, and John the Baptist was not alive when Scripture says he leaped for joy.
(d) "In Numbers 5, God Himself commanded an abortion."
At its strongest: In the ordeal for a wife suspected of adultery, the priest says: "may the LORD make you a curse and malediction among your people by causing your uterus to fall and your belly to swell!" (Numbers 5:21). Some read this as God causing the miscarriage of an adulterous pregnancy, which would mean God Himself sanctioned ending a pregnancy.
Answer: The text never says the woman is pregnant, and the NABRE offers no note suggesting she is. The outcome for an innocent wife is that "she will be immune and will still be fertile" (Numbers 5:28), which suggests barrenness, not miscarriage, as the curse on the guilty. The rite was a drink of "the water of bitterness" (5:24), not a drug or a procedure, and its outcome was left entirely to God. And God is "the Lord of life from its beginning until its end" (CCC 2258). Whatever God does as Lord of life grants no human being the right to take an innocent life. The same paragraph says plainly that "no one can under any circumstance claim for himself the right directly to destroy an innocent human being."
(e) "My body, my choice."
At its strongest: Even if the unborn child is a person, no one may be compelled to use her body to keep another alive. We do not force anyone to donate a kidney, even to save a life. Pregnancy is nine months of profound bodily sacrifice; requiring it is a form of bodily conscription.
Answer: There are two bodies here, not one. The child has his own life, his own genetic identity and his own future: from the first instant, as the Catholic Church notes, genetic science shows "the program of what this living being will be: a man, this individual man with his characteristic aspects already well determined" (Declaration on Procured Abortion 13). Abortion is not simply declining to help a stranger; it is a direct act that kills.
And a child is not a stranger. Parents owe their children what they owe no one else. No one believes a mother may leave her newborn to starve because feeding him costs her body, sleep and freedom. The womb is not a stranger's hospital bed; it is where every one of us began, the natural home God made for the child. For Christians there is a further truth: "you are not your own… you have been purchased at a price. Therefore, glorify God in your body" (1 Corinthians 6:19–20).
(f) "What about rape, danger to the mother, or a grave diagnosis?"
At its strongest: A woman who was raped did not choose pregnancy. A mother with a life-threatening condition may die without treatment. Parents who learn their child will be severely disabled face suffering they never chose. Forcing any of them to continue a pregnancy seems cruel.
Answer: These are the hardest cases, and they deserve compassion before argument. Rape is a grave crime, and the woman deserves protection, care and justice. But her child is a second innocent person, not the criminal. Killing the child does not undo the violence done to the mother; it adds a second victim. Scripture forbids the reasoning that "we should do evil that good may come of it" (Romans 3:8). The Catechism states the principle plainly: "One may not do evil so that good may result from it" (CCC 1756).
When a mother's life is in danger, the Catholic Church never treats her life as worth less than her child's. Urgent treatment of a serious condition is permitted even if the child dies as an unintended result (Directive 47). What is forbidden is directly killing the child as the means (Directives 45 and 48). And a disability never lessens a person's worth. Of the man born blind Jesus said: "Neither he nor his parents sinned; it is so that the works of God might be made visible through him" (John 9:3). Every child, healthy or not, can say: "I praise you, because I am wonderfully made" (Psalm 139:14). The Christian answer to hard cases is not a quicker death but more love: from families, parishes and every one of us.
(g) "Even some saints thought the soul came weeks after conception."
At its strongest: Some Fathers and medieval theologians, following ancient biology, held that the rational soul is infused some weeks after conception. If so, an early abortion would not kill a human person.
Answer: Grant the history: "There is not a unanimous tradition on this point and authors are as yet in disagreement" (Declaration on Procured Abortion, note 19). The same document admits that in the Middle Ages "a distinction was made in the evaluation of the sin and the gravity of penal sanctions," with lighter penances for abortion in the earliest weeks. Yet, it adds, "it was never denied at that time that procured abortion, even during the first days, was objectively grave fault" (Declaration 7). So notice three things. First, the same Christian writers condemned abortion anyway, at every stage. St. Basil wrote: "With us there is no nice enquiry as to its being formed or unformed" (Letter 188, canon 2). The debate was about when the soul is created, never about whether early abortion was permitted.
Second, even a probability settles the question: "it suffices that this presence of the soul be probable (and one can never prove the contrary) in order that the taking of life involve accepting the risk of killing a man" (note 19). "From a moral point of view this is certain: even if a doubt existed concerning whether the fruit of conception is already a human person, it is objectively a grave sin to dare to risk murder" (Declaration 13). A hunter who is not sure whether the movement in the brush is a deer or a man may not shoot. Third, the old opinion rested on ancient biology. Modern embryology shows that a new, living, genetically distinct human organism exists from fertilization.
The Early Church Agrees
- The Didache (Teaching of the Twelve Apostles 2, c. AD 80–100): "you shall not murder a child by abortion nor kill that which is begotten" (newadvent.org). Within living memory of the apostles, abortion is filed under murder.
- The Epistle of Barnabas (ch. 19, c. AD 130; by an unknown author, not the apostle): "You shall not slay the child by procuring abortion; nor, again, shall you destroy it after it is born" (newadvent.org). The unborn and the newborn stand under the same protection.
- The Epistle to Diognetus (ch. 5, 2nd century), describing what set Christians apart: "They marry, as do all [others]; they beget children; but they do not destroy their offspring" (newadvent.org).
- Athenagoras of Athens (A Plea for the Christians 35, c. AD 177), defending Christians to the emperors: "we say that those women who use drugs to bring on abortion commit murder, and will have to give an account to God for the abortion." Christians, he says, "regard the very fœtus in the womb as a created being, and therefore an object of God's care" (ccel.org).
- Tertullian (Apology 9, c. AD 197): "To hinder a birth is merely a speedier man-killing; nor does it matter whether you take away a life that is born, or destroy one that is coming to the birth. That is a man which is going to be one; you have the fruit already in its seed" (ccel.org).
- The Council of Ancyra (canon 21, AD 314) addressed women "who commit fornication, and destroy that which they have conceived, or who are employed in making drugs for abortion." An earlier rule had excluded them from Communion until death; the council, "desirous to use somewhat greater lenity," set ten years of penance (newadvent.org). Grave sin, and a road back.
- St. Basil the Great (Letter 188, canon 2, AD 374): "The woman who purposely destroys her unborn child is guilty of murder. With us there is no nice enquiry as to its being formed or unformed." Yet he insists the penitent's treatment "depend not on mere lapse of time, but on the character of their repentance" (newadvent.org).
From the first century to the fourth, in Syria, Greece, North Africa and Asia Minor, the witness is the same: the child in the womb is a human life under God's care, and deliberately destroying it is murder. As the Catholic Church summarizes, "The tradition of the Church has always held that human life must be protected and favored from the beginning" (Declaration on Procured Abortion 6). And from the start, the same Church that called abortion murder also welcomed penitents back.
If You Have Had an Abortion
If you are a mother who has had an abortion, a father who paid for one or pushed for one, a grandparent, a friend who drove, or a doctor or nurse who took part, this section is for you.
Pope St. John Paul II wrote words the Catholic Church still speaks to every woman who has had an abortion: "I would now like to say a special word to women who have had an abortion." He does not pretend it was nothing: "Certainly what happened was and remains terribly wrong." "But do not give in to discouragement and do not lose hope." "The Father of mercies is ready to give you his forgiveness and his peace in the Sacrament of Reconciliation." And: "To the same Father and his mercy you can with sure hope entrust your child" (Evangelium Vitae 99).
The God who says "You shall not kill" is the same God who says, "Though your sins be like scarlet, they may become white as snow" (Isaiah 1:18). "If we acknowledge our sins, he is faithful and just and will forgive our sins and cleanse us from every wrongdoing" (1 John 1:9). "As far as the east is from the west, so far has he removed our sins from us" (Psalm 103:12). St. Paul, who once approved the killing of Christians, wrote: "Christ Jesus came into the world to save sinners. Of these I am the foremost" (1 Timothy 1:15).
Here is what to do. Go to confession: every Catholic priest has the faculty to absolve this sin (Misericordia et Misera 12). If you are not Catholic, talk to a priest anyway; he will listen and help. For healing, the Catholic Church in the United States offers Project Rachel, "a ministry of the Catholic Church in the U.S. to those who have been involved in abortion" (USCCB); find the nearest diocesan ministry at HopeAfterAbortion.com. "Hence, now there is no condemnation for those who are in Christ Jesus" (Romans 8:1).
Conclusion
Is abortion a sin? Scripture gives two truths that cannot be separated: God forbids the deliberate killing of the innocent, and the child in the womb is an innocent human being whom God knows, forms and calls by name. The conclusion follows, and the first Christians drew it within living memory of the apostles: "you shall not murder a child by abortion." The Catholic Church teaches the same today, unchanged and unchangeable, and with the same breath offers the mercy of Christ to every person who has taken part in an abortion.
This is not a rule imposed on women. It is a promise made to every child and every mother: that no one's worth depends on being wanted, healthy, convenient or born, because every one of us was first known and loved by God in the womb.
Come home. The Church that has defended every unborn child since the Didache, and that opens the confessional to every mother and father who regrets an abortion, is the Catholic Church. Christ did not found many churches. He founded one, on St. Peter and the apostles (Matthew 16:18), and that Church is the Catholic Church. "It is through Christ's Catholic Church alone, which is the universal help toward salvation, that the fullness of the means of salvation can be obtained" (CCC 816). If you are a baptized Christian, you already share "a certain, although imperfect, communion" with her (CCC 838). Every truth you already hold is a call to the rest of the way. If you are not yet a Christian, we invite you to come and see. Christ is calling you into the Catholic Church.

FAQ
Is abortion an unforgivable sin? No. Abortion is a grave sin, but "there is no sin that God's mercy cannot reach and wipe away when it finds a repentant heart" (Misericordia et Misera 12). Every Catholic priest can absolve it in confession.
Is a miscarriage a sin? No. A miscarriage is the natural loss of a child, not a choice. It is a real death and a real grief, and parents may name their child, pray for him or her, and entrust the child to God's mercy.
What does the Catholic Church say if the mother's life is in danger? Urgent treatment of a serious condition that cannot wait until the child can survive is permitted, even if the child dies as a result (Directive 47). What is never permitted is directly killing the child as the means of treatment (Directives 45, 48). The Catholic Church protects both lives.
Does the Catholic Church consider ending a pregnancy before implantation an abortion? Yes. The U.S. bishops' directives state that every intervention "whose sole immediate effect is the destruction of a living human embryo or fetus or the removal of a living embryo or fetus from the uterus before viability is an abortion, which, in its moral context, includes the interval between conception and implantation of the embryo" (Ethical and Religious Directives, 7th ed., note 46).
Is everyone who has an abortion automatically excommunicated? Canon law attaches an automatic excommunication to procuring an abortion (canon 1397 §2), but those under sixteen, and others with lessened responsibility such as minors and those acting under grave fear, do not incur the automatic penalty (canons 1323–1324). In every case the act is gravely wrong, and in every case the way back is the same: confession.
