The answer
If a person is deemed by the medical community as being permanently comatose and in a pervasive, irreversible, and vegetative state, the church may relieve the patient and the family from artificial means intended to extend the patient's life. This process ought to be performed with the most dignity to the patient and the family.In cases of severe irreversible comas, many organs may still be functioning, due to artificial means. When the medical staff determines that the patient is "brain dead" and cannot survive without the support of artificial means, then the family may consult with the clergy to terminate the use of heroic measures and allow the patient to depart in peace, as eventually all the organs will shut down.
Organ donation is considered an act of mercy and kindness, symbolizing the ultimate final expression of brotherly love and self-sacrifice on behalf of the dying patient. The church does support enrollment in organ donor programs.
