Version 7.2.1
The Vatican's updated ethics guide on xenotransplantation makes clear that using animal organs for human transplants is morally sound when done responsibly. Catholic theology has no religious objection to any animal species as a source of organs or tissues, and genetic modifications are acceptable when animal welfare and biodiversity are respected. This is a thoughtful, humane framework that puts lifesaving medicine on solid moral ground.
Blessing animal-to-human organ transplants ignores a dark reality — experiments on brain-dead patients using animal organs have already failed and caused needless suffering. Mixing animal and human biology echoes a profound spiritual warning about corrupting God's created order. The Vatican may be paving the way for more exploitation under the guise of compassion.
