God designed the human race

"to reproduce by the union of man and woman. Every child has the right to be born of a father and a mother. Human cloning violates God’s design by trying to create a child with only a genetic father or only a genetic mother.

"Human cloning also involves abortion because the 'rejected' or 'unsuccessful' embryonic clones are destroyed. Some people want to create human clones simply to experiment on them, yet each clone is a human being."
