Is the Church opposed to stem cell research?

The Church is not opposed to stem cell research as long as it is conducted in an ethical manner. Adult stem cell research, in particular, is recognized as holding promise, but there are grave problems with embryonic stem cell research.

In 2005, Pope John Paul II stated: “The Church’s position, supported by reason and science, is clear: The human embryo is a subject identical to the human being who will be born at the term of its development. Consequently whatever violates the integrity and the dignity of the embryo is ethically inadmissible. Similarly, any form of scientific research that treats the embryo merely as a laboratory specimen is unworthy of man. Scientific research in the field of genetics needs to be encouraged and promoted, but, like every other human activity, it can never be exempt from moral imperatives; research using adult stem cells, moreover, offers the promise of considerable success.”
