Thinking Milton's Thoughts about the Fruit of Knowledge

Back in 2006, I was thinking about this question concerning Milton's view of the fruit of the Tree of Knowledge

The question that I'm attempting to answer in my paper -- or one of the questions, anyway -- is precisely what the term "sacred" means when used by Milton to describe the tree of knowledge and its fruit. In biblical thought, "sacred" can mean either "set apart from profane things" or "imbued with a divine, dynamic power" (or both), so which one of these two possibilities does Milton mean?

I'll say more about this query if I can find an electronic version of the article that I came to write.
