I have been wondering if there is a natural law argument to be made for the goodness of the body. Sure, it's great to denounce meaningless views of the body, but some people need some further preparation before they accept that their body is meaningful because it is created by God. I was looking for an argument like Aquinas makes against murder: even murderers resist being murdered. But, being rather uncreative myself, I was struggling to establish one. Then I came across this sentence in Ephesians 5:

"For no one hates his own flesh but rather nourishes and cherishes it, even as Christ does the church, because we are members of his body."

Voila!

Of course, there seem to be an objection to this: certain terminally ill people definitely come to see their body as a cage, and hate it. So have I really developed a natural law argument? Well, it seems my reasons are no more objectionable than Aquinas', and that's a pretty good standard.
