Life often presents difficult moral choices, especially when it comes to growing families, health, suffering, and end-of-life decisions. As Catholics, we are not alone in these moments.
The Church offers both teachings and encouragement rooted in love and human dignity. Michael Vacca, a director and bioethicist at CMF (Christ Medicus Foundation) CURO, answers five common bioethical questions you may face when making decisions and explains how your faith can help guide you.
1. What kind of care are we morally obligated to receive as we near death?
As Catholics, we believe in the sanctity of life from beginning to end. When approaching death, we are called to provide and accept basic care — including food and water, even by feeding tubes if necessary — as long as the body can absorb them.
Pain relief is also morally acceptable and even compassionate, provided it’s not given with the intention of ending life. Ordinary treatments like antibiotics or wound care are typically required if they offer real benefit without disproportionate burden.
Above all, don’t forget spiritual care. Receiving the Sacraments — Confession, the Eucharist (Viaticum), the Anointing of the Sick, and the Apostolic Pardon — prepares the soul for eternity. Consciousness, if possible, should be preserved to meet Christ fully awake and at peace.
2. How can I protect my life — and my conscience — when I can’t make decisions myself?
It’s wise to prepare. Rather than relying solely on written documents that may be misinterpreted, Catholics are encouraged to appoint a trusted proxy — someone who knows Church teaching and loves you enough to honor your values.
Avoid general phrases in legal forms like “no extraordinary care,” which can be misunderstood. Instead, express your values: a desire for food, water, and Sacraments, and a commitment to upholding your dignity in life and death.
In the U.S. healthcare system, euthanasia is rampant. People are routinely denied food and
water, overmedicated, and otherwise improperly cared for because they believe the lie that they should not burden others with their care. We are called to be our brother’s keeper and
burden each other as God wills.
When considering hospice care, ask questions. Some hospices do not guarantee basic needs, such as food or hydration. The Healthcare Advocacy and Leadership Organization (HALO) offers a guide to help you choose wisely.
3. What should Catholics know about vaccines?
Medical decisions should always respect freedom of conscience. Vaccines, like all medical interventions, must never be forced. The Church teaches that health care choices — including vaccination — must be made voluntarily and with a well-formed conscience. Coercion, whether social or institutional, undermines human dignity and moral responsibility.
When considering whether to receive a vaccine for yourself or your children, it’s important to weigh three factors:
- Safety and Effectiveness: Consider the risks and benefits. Some vaccines are well-established and supported by years of safety data. Others, especially newer or experimental ones, may still lack long-term testing. It’s prudent to ask whether the vaccine is necessary for your current situation and whether safer alternatives exist.
- Moral Origins: Many modern vaccines are developed or tested using cell lines derived from tissue of aborted children. While the Church has said that, in grave situations and with no alternatives, receiving such a vaccine may be morally permissible (if done without approving the original evil), Catholics should always seek ethically produced options when available. The resource Children of God for Life offers updated information on which vaccines involve these cell lines and which do not.
- Conscience and Prudence: If, after prayerful reflection and research, you believe a particular vaccine is morally or medically inappropriate for yourself or your children, you are under no obligation to receive it. The Church defends the right of conscience and supports your ability to decline medical interventions without sin.
The Congregation for the Doctrine of the Faith emphasized this in 2020 in its “Note on the Morality of Using Some Anti-COVID-19 Vaccines,” stating that vaccination as a rule and a moral obligation “must be voluntary.”
4. Should I be an organ donor?
Organ donation can be an act of love, but it must be done morally. Under current organ donation systems, organs are often removed before true biological death; you might be declared “brain dead” when you are still alive. Since you are considered “dead,” medical professionals can paralyze you with drugs and harvest your organs. This violates a central principle of Catholic bioethics known as the “dead donor rule”: the rule that you cannot be killed for your organs. The American Academy of Neurology (AAN) has recently made it easier to prematurely declare people dead and harvest their organs. In its report, the AAN even admits to the lack of high-quality evidence on “death by neurological criteria” or so-called “brain death.”
The reality is that brain injured people are alive and deserve good medical care until God sees fit to call them home.

The Church supports organ donation after true death but not if the process compromises the dignity of the donor. “Brain death” criteria can be unclear or prematurely applied. It’s important to be cautious and informed.
If you’re already registered, you can ask for help in removing your name. Note that simply removing the heart from your driver’s license does not mean your name has been removed from the organ donor registry. An attorney or pro-life advocacy group can assist you if needed.
5. What if we’re struggling to conceive?
The Church honors the deep longing for children — it’s a sacred desire. However, the Church teaches the dignity of life and the marital embrace must never be separated. Technologies like IVF, while born of love, are not morally acceptable because they bypass God’s design.
Embryo adoption carries with it similar concerns and has undergone serious debate among Catholic bioethicists. Definitive church teaching has yet to be decided. However, the Congregation of the Doctrine of the Faith issued a statement in its Dignitas Personae (2008).
“It has also been proposed, solely in order to allow human beings to be born who are otherwise condemned to destruction, that there could be a form of ‘prenatal adoption’. This proposal, praiseworthy with regard to the intention of respecting and defending human life, presents however various problems not dissimilar to those mentioned above.”

There is hope, though. Natural Family Planning (NFP) can assist couples in understanding fertility. Catholic fertility specialists, including those using NaPro technology, can help identify and treat root causes in a morally respectful way and even restore reproductive health — something IVF cannot do. And if natural conception isn’t possible, consider prayerfully discerning foster-parenting or adoption, which are beautiful means of building up the Kingdom of God.
We will all encounter hard choices, especially in today’s medical landscape. But we are not alone. Christ walks with us, and His Church provides guidance that protects both body and soul. When in doubt, seek pastoral or ethical counsel grounded in faith.
