The Chrchâs domain is Faith and Morals, not science. The Vatican discusses various issues with scientists and may make a decision wrt morality, but does not issue a decision *about science per se. *
The Vatican accepts that medical science has deemed brain death to be death.
So letâs consider the reality of brain death: if a personâs brain stops functioning altogether, the bodily functions regulated by the brain stop. One of those bodily functions is breathing. If a person stops breathing, their heart, deprived of oxygen, will stop beating. Then we will know they are dead by the old criteria.
There was no need for different criteria until the advent of organ transplants. If we test to see if someone is dead by taking them off the machine and seeing if their bodily functions come to a halt, then the organs begin to deteriorate so quickly they are no longer good for transplanting.
Pope Benedict had an organ donor card until he became Pope.
You are correct when you say that this case is not cut and dry like the Terri Schiavo case. In her case, her husband wanted to withdraw *ordinary *care, food and water, from a person whose body was still very clearly maintaining itself. In no way could Mrs Schaivo have been considered dead at all; the food and water were not harming her as they do to patients at the point of death.
In this case, the situation is very different *and *we lack information. This latter point is probably why no bishop has made any sort of statement.
