As a reformed Catholic and product of Catholic schools myself, I think your patient’s son misunderstood Catholic teaching on withdrawal of care in end of life situations. I currently work in a Catholic hospital and while we don’t do tubal ligations, elective abortions, or administer contraceptives, we withdraw care all the time.
Many of these folks (including my patient’s son, I think) already mostly have a preconceived notion of what they think end-of-life care should entail and then use their religious beliefs to enforce these notions. My pt’s son used to say over and over how strong his dad was and how much of a fighter he was...you can just imagine how he felt after months of his dad hanging around- having survived big surgeries, fighting off a ton of minor problems, receiving a bazillion pints of blood- that a small cough and fever was the thing that was bringing him down. He just couldn’t accept it.
That being said, perhaps the Catholic Church does accept withdrawing care in particular circumstances, but take a look at the vagueness of the following
“For instance, Catholics have a moral obligation to use "ordinary or proportionate means" of preserving their lives, if the means provides a "reasonable hope of benefit and do not entail an excessive burden, or impose excessive expense on the family or the community" (ERD 56). If the patient feels the benefits are not reasonable, or entail an excessive burden, he or she may forgo those means (ERD 57).”
Furthermore, take a look at what the US conference of catholic bishops wrote less than 10 yrs ago:
“While medically assisted nutrition and hydration are not morally obligatory in certain cases, these forms of basic care should in principle be provided to all patients who need them, including patients diagnosed as being in a “persistent vegetative state” (PVS), because even the most severely debilitated and helpless patient retains the full dignity of a human person and must receive ordinary and proportionate care.”
When you have a group of people who think that trach/peg’ing a vegetable somehow maintains human dignity, who is to say that my pt’s son was wrong to think trach/peg for his father was anything but “ordinary?” The question is not whether withdrawing care is compatible with Catholicism- it’s whether one can say that prolonging life in such a miserable fashion is expressly
not compatible, which opens up a whole can of philosophical No-True-Scotsman problems . Obviously we can’t say that considering many Catholic websites and leaders have had to go out of their way to clarify and dispel myths and to say that things such as DNR and palliative care have become acceptable in the last 30 yrs even though they were unacceptable for a whole slew of Catholics for the preceding 300 yrs.
