The ‘fertilization’ part is also not without problems. Do moles and uterine cysts suddenly count as legal dependants?
Also, what happens to ectopic pregnancies, we end about 50,000 to 150,000 of them each year in Catholic hospitals now?
Regarding the Teri S. comment above, it is a difficult situation. ‘Never recover’ does not mean that we can dismiss the infinite value of the gift of life. And, as a general belief, Catholics do not view nutrition and hydration as extraordinary means (though the poor woman had lost the ability to accept either of those without medical assistance). The Church does give us some latitude regarding death with dignity, and there are some situations where even hydration and nutrition are potentially ‘extraordinary care’.
On a personal level, I find I have great sympathy for eveyrone involved, the woman, her parents, the husband. It is easy to pass moral judgement from a distance. But we are all sinners and we have not had to walk in their shoes.
