Nigel Cameron is President of the Institute on Biotechnology and Human Future. In his commentary this week on Christianity Today's website, he addresses the question of the bioethics of Bethlehem. What happened nine months before the manger?

Here's a couple clips:

God took human form; and he took it not simply as a baby, but as the tiniest of all human beings, a mere biological speck, so small and so undeveloped that it could be mistaken for a laboratory artifact, a research specimen, an object for human experimentation. But this speck was God; this complete genetic human organism, in its primitive and undeveloped form, was so much "one of us" as to bear the existence of the Creator. He dignified humanity by taking the form of this creature he had made in his image; and he did it at the most inauspicious and feeble point in the human life story. At the heart of the Christmas celebration lies the fact of all facts, that God became a zygote...

It is important to realize that there are several powerful arguments against using human embryos for research... We believe that all human beings are made in the image of God. We believe that Jesus Christ was God taking human form for himself. And we believe that we started right at the beginning—that incarnation took place in embryo.
