I believe one issue that really opens this up to interpretation is that God really doesn't spend very much time writing things down. Pretty much everything we know is what someone else has written about God.
As far as I know, and I may be wrong, the only thing written with the finger of God was the commandments, and I think the number of them vary depending on the section of whose different writing one reads. The problem is Moses came down from the mountain, got upset and destroyed them because people were dancing around a golden calf or some such thing. So he had to go back up and ask God to re-write the commandments and oddly, the first one in the re-write was about having other Gods before the God of Abraham. Not that there couldn't be other Gods, just none before that One.
Of course there can be libertarian underpinnings taken from the Bible, just as there can be from Judaism, Hinduism, even Islam (see the Minaret of Freedom Institute
http://www.minaret.org/). I don't mean to discourage any effort to identify such libertarian Biblical quotations. I think it is more important, however, that the founders of American government were able to separate, at least in theory, religion from government than it is that some if not all were Christian. When it comes to identifying the role of government, I prefer Locke and Jefferson to Paul and Moses.
