brbubba, I am concerned you are making things too hard. A "can't see the forest for the trees" sort of thing. I know you want to argue about the definition of nature even when I thought the intent was clear and even gave a definition for it, but since you brought up definitions maybe I can help you out a bit more.
Pantheism is the view that the Universe (Nature) and God are identical...
Wikipedia: Pantheism
In the 17th century Benedict de Spinoza formulated the most thoroughly pantheistic philosophical system, arguing that God and Nature are merely two names for one reality.
Encyclopædia Britannica
pantheism1. the doctrine that God is the transcendent reality of which man, nature, and the material universe are manifestations
2. any doctrine that regards God as identical with the material universe or the forces of nature
Collins Discovery Encyclopedia
So it appears that "nature" can and in fact is, or at least can be, part of the definition of Pantheism (and subsequently pantheists). You argue that I should have clarified what I meant by "nature", if you reread my post that you quoted you would see I did.
Hopefully this can be left now. Hopefully I have made my view, imperfect as it may be, clearer. I am also hopeful you did not take offense at this, or another of my responses to your reply to my original post. Just to be clear: by "not take offense" I mean:
not: a logical operator that produces a statement that is the inverse of an input statement
take: to obtain by deriving from a source
offense: the state of being insulted or morally outraged
