I really don't know why you are trying to pick a fight about an issue about which we probably agree.
The Catholic position is that each human child is conceived by its mother and father, has its genes from both parents, and is ensouled directly by God.
Also, by no means do I believe that "natural law" is some sort of materialist billiard table.
I'm not trying to pick a fight. We simply disagree that each human life represents a miracle of God. I don't even remotely view such a disagreement as anything more than a curiosity. I was merely looking for more insight into your original statement. You gave it to me. Thank you.
