Perhaps the question the Pope would invite you to ask yourself is why won't you embrace the child that God sends you...
I can understand that perspective. But it seems that there are any number of things a parent can do to a child, even permanent things, that are a not seen as a rejection of God's plan the same way genetic engineering is.
If a mother gave her child laser eye surgery to correct his vision, I don't think the Pope would suggest that the mother had failed to embrace the child God gave her. But if the mother had changed the genes that determine the child's vision...that seems to be different.
Why is that? In both cases, the mother is using artificial means to make a permanent change to their child, in an effort to make them more "perfect". What is it about the genetic method that is morally worse than the surgery method?
