The Vatican considers transplants ethically and morally acceptable and donation is encouraged as an act of charity. Pope John Paul II, in an address to the participants of the Society for Organ Sharing said, “With the advent of organ transplantation, which began with blood transfusion, man has found a way to give of himself, of his blood and of his body, so that others may continue to live.” The Holy Father also added, “The medical act of transplantation makes possible the donor’s act of self-giving, that sincere gift of self which expresses our constitutive calling to love and communion.”
