It's as meaningful as the person who reads and interprets it. It turns into an ethics without form or purpose.
For me, man is a rational animal. It therefore is our ethical obligation to do those things which are in accord with right reason.
Now, of course, if you don't believe in a Creator, you can't do ethics this way, or not for very long, because there's no reason to think that anything is purposed for anything anyhow. But then if you don't believe in a Creator, it becomes very difficult to do ethics of any sort, IMO.
