It is an interesting, and yes, controversial question. Stem cell research can help to cure many diseases. They are just cells-just like skin cells, sperm cells, or ova, which human bodies shed daily. They are not even capable of independent life without support in culture media.
Yes, all life is sacred, I agree. All life going back to primordial first cell. But there is a difference, the total human is more than just a sum of the parts. And the parts are less than the whole. And what about cancer cells, do you object when a doctor cures cancer? To do it, you have to kill human cells.
So here is the question. We all have more reproductive cells than we can use in fifty lifetimes for children. Even many fertilized ova abort naturally.
So by banning stem cell research, one is condemning many people to more suffering and death-people that could be cured with the findings from stem cell research. Children are wonderful- a blessing, and ART help parents have children. There are always some spare cells which can be donated to help others.
Besides, if stem cell research is allowed to continue [ethically, of course] then researchers may find ways to develop stem cells from ordinary cells. But it takes time, and further research. Some progress has already been made.
I know folks feel that they must obey the doctrine of the church. But I personally think that there is more compassion, more humanity, in saving lives through this science.
The church is sometimes wrong-it is fallible. They got the thing about Mary Magdeline wrong-Christ’s friend and confidant, and they called her a whore for 1700 years. I think they will change their minds about stem cell research too, and good Catholics can help them do so.
Ethics is about finding solutions to hard questions, and sometimes there is no easy answer. But before anyone dismisses stem cell research, and tries to get it banned -think of this. You are condemning many people to more pain and death. Do you really have the right to do that? Some people, are not Catholics, so is it right to try to deny everyone in the community access to this medical technology on the basis you think it is wrong?
Catholics are free to refuse the product of stem cell research on the basis of conscience, or you can refuse to donate to such research. Also fine. No problem. But some are trying to get it banned from the whole community. And that is wrong. There are people who are not Catholic, and do not believe in the same things.
