No one is trying to make a perfect world. What they are trying to do is figure out how to get a liver transplant, or a heart transplant, for someone who desperately needs one. What they’re advancing is the older use of porcine and bovine cells that produced insulin and then became human insulin produced by recombinant DNA engineering of animal islet cells.
They might be able to find ways to produce skin and bone to graft onto trauma victims. This is not a moral absolute. This is humanity doing what we need to survive.
Actually helping and loving other people IS a moral absolute.
James 2:8 “If you really keep the royal law found in Scripture, “Love your neighbor as yourself,” you are doing right.”
There are limits on that of course. We can’t morally murder someone to help someone else. Personally? I’m not going to walk by a wounded traveler or simply say a prayer on his behalf. I’m going to try to act like a good Samaritan.
We DON'T need to do this stuff to survive. The human race has managed to survive for thousands of years without hybridizing man and animals.
