• As with animal cloning, the use of animals as a source of organs for transplants is not an issue that Aquinas would have thought about, nevertheless his account of natural moral law would on the whole approve of it:
• Humans do have the moral right to use animals in any way they see fit, so with certain safeguards, using animals as a source of organs for transplants would probably be acceptable to Aquinas’ natural moral law. The safeguards would include any attempt to modify the human germline, which would be a modification of God’s blueprint for humans at creation.

  ‘… We are opposed to any xenotransplantation which might modify the germline, and particularly to any transplantation of sex organs or gametes. We are opposed to any use of human tissue for transplantation into animals.’
